Introduction</h2>
Every so often I hear some disturbing comments, or someone makes one to this blog. Dealing with the twist rate discussion takes some time. The gas check question is easier to deal with. The problem usually comes up when a fellow caster and handloader reads their first book on each topic. I don't know if that's exactly the scenario for the comment made here, but I want to use it to make my points.<br />
<br />
Here is the comment, which I believe represents typical thinking for a small number of fellow casters:<br />
<br />
<div class="comment-content" id="bc_0_1MC">
<em><strong>"Remember, twist rate favors different "length" bullets, and not necessarily weight. <br /><br />Also, my personal opinion is that gas checks aren't needed in .357mag. You may have to dork around with the correct hardness/size, but a flat base with correct obturation will prevent gas cutting.<br /><br />(I just finished reading a book on Elmer Keith's work. Pardon me if I sound snarky)"</strong></em></div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
Now for my response.</div>
<div class="comment-content">
<br /></div>
<h2 class="comment-content">
Twist Rates</h2>
<div class="comment-content">
Technically this is correct about twist rates. If you look back at prior posts I actually do mention that fact it's really about length, and also weight. However for a given nose and lube groove configuration, a longer bullet will weigh more. A shorter bullet will weight less. It's as simple as adding lead to make a bullet longer has to make it weigh more. Based on that simplification, a heavier bullet is usually longer than a lighter bullet. Read on before you object.</div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
The nose and lube grooves being the same is key to my claim. Bullets with a different nose/lube groove configuration may vary from this. Generally, a SWC with the same weight as a RNFP will be longer. If the nose had less diameter, it simply has to be longer to weigh the same. So a full wadcutter, with no thin nose to add length, will be the shortest bullet for a given weight. Bullets that are a blunt shape will also be shorter than one with a long thin nose. OK, are we all on the same page. Oh, tumble lube grooves are also shorter than a single large conventional lube groove too, so this is another consideration.<br />
<br />
However, it becomes tedious to have to type that in every time twist rates are metioned, so I don't. I expect the reader to understand that. I'd prefer to use the short version and talk weight.<br />
<br />
Handloaders (or readers) do find it more helpful and informative if I mention a 145 RF vs a 173 SWC. Talking to .580 inches and .744 inches just isn't helpful. Again, it gets tedious to mention both weith and length every time, unless the article or post is specifially on the subject of twist rates and bullet design.</div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
Why do we care about twist rates anyway? The rate of twist will determine which bullets will stablize in a gun. For 357 revolvers, typical twist rates are 1 in 16 to 1 in 18 inches. The longer the measurement, the slower the twist. Slower twist means a shorter, and generally lighter bullet will stablize and be more accurate. Small changes in twist don't have a huge difference, in handguns. Also, shorter barrel guns may need a faster twist than a rifle and it's long barrel. The magnum revolvers were standardized (roughly) years ago, and will shoot bull house loads with heavier bullets. That's one reason the 358-429 shoots so well.</div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
There are some good calculators to get in the ballpark bullet length/weight for a rifle. The Greenhill formula is one that has been used for years. There are variations that allow for velocity and other addtional varibles. Another more current calculator is <a href="http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi" target="_blank">http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi</a> that is extremely useful. This calculator uses diameter, length, velocity and weight by the way, which makes it very different than the Greenhill formula. Note: If you do some reasearch you will discover that bullets up to a 3.5 stability number maintain their accuracy. That's different than what is posted on the JBM webpage. From my rifles I shoot bullets with a 2.5 to 3.4 factor with excellent results. If you plug in numbers for your revolver, the results may indicate the bullets will overstabilize and not be accurate. Don't worry, just don't use it for your 357 revolver.</div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
I hope this was helpful. In the future I will not post all of this every time I mention twist rate and bullet weight and length. I will use the shorthand version and simple metion twist and weight. Otherwise, it's just to tedious and repeditive. That's the last time I beat that drum.</div>

Gas Checks</h2>
<div class="comment-content">
<br />
As you know, I'm a fan of the 358429 bullet designed by Elmer Keith. He didn't like gas checks in 357 or 44 Magnums. At least in revolvers. However he's not the only accomplished bullet designer out there. Check out some of the info regarding Ray Thompson <a href="http://www.americanhandgunner.com/to-check-or-not-to-check/" target="_blank">http://www.americanhandgunner.com/to-check-or-not-to-check/</a> who created the 358156. It's a gas checked bullet for the 357 that many consider the best design for my favorite caliber. Also Skeeter Skelton wrote some great articles and is rather famous too. He has pet recipes for both the 358429 and the 358156.</div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
I haven't posted a detailed review of the 358156, but I will do one soon.</div>
<div class="comment-content">
<br />
I have found in lever rifles, that gas checks really extend or raise the usable velocity, at leadt for mid-weight bullets (140-150 grains). I get a very accurate 1,850FPS with a 145 RF design with a gas check. Without a check, the accuracy falls off after 1,500 FPS. That's a significant difference. It's worthy of a gas check. <br />
<br />
This fact alone dispells the statement that 357 Magnums don't need a gas check. To wring the last bit of perfomance out of a 357 rifle, and to avoid leading, gas checks are needed and useful. You can agree or not, get a 357 rifle and do your own tests. </div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
The Rossi has a faily slow 30 inch twist, so the lighter bullets that it likes shoot at a higher velocity. A Marlin with a much faster twist (16 or 16.5 if memory serves me correctly) will shoot heavier bullets well. The Henry has a 38 inch twist, which to me seems bizarre, but it shoots well too.<br />
<br />
The poster of the comment and many others choose to not use gas checks in a 357. There are others that use the Thompson design and use checks all the time, in their rifles and in revolvers. I have no problem either way. <br />
<br />
I have no issue with everyone having their own opinion. Just don't expect everyone to agree that gas checks are not needed or helpful in a 357, espcially when there is someone like Ray Thompson who's designs are outstanding. The 358156 shooters are getting their own great results.</div>
<div class="comment-content">
<br /></div>
<div class="comment-content">
I think Skeeter got it right. The real point is what bullet / load combination shoots best. He uses the 358429 without gas checks, and the 358156 with gas checks. They are both excellent.<br />
<br />
If you don't believe me, just Google away. Or cast some and head to the range.</div>

I haven't been able to post for some time as work has been crazy. That's good, not having work would be tough. Anyway, I've been testing a cutomer 145 grain round nose / flat point bullet in revolvers and lever action rifle. I also have a 168 grain version to discuss too.<br />
<br />
I'll refer to these as my first generation custom molds. I went through several designs and found some noses that worked and some that didn't. In the near future I'll cover the good and the bad. I already have orders placed for generation 2, or Version 2.0.<br />
<br />
The question is, what is the optimum bullet size for a 357 magnum rifle, in this case the Rossi. It has a slow 30 inch twist, which like lighter bullets. Then what is the optimum bullet size for 357 magnum revolver, something in the 16 to 16.5 inch twist range. Which likes heavier bullets, with high velocity.<br />
<br />
The answer I came to is that the 140-150 grain range would provide the shorter length that the rifle would like. It also turned out to work really well in the revolver. <br />
<br />
Here is the bullet, which exits the rifle barrel at 1,850 FPS, and the six inch revolver at 1,400 FPS. It's a little hot for the handgun so I don't shoot it often. In the rifle, this bullet has more energy at 100 and 200 yards than a 125 or a 158 grain bullet. With a gas check, it is a sweet hard hitting shooter. Accuracy is very good, but not stellar. So 2 MOA at 100 yards is very repeatable, but more about that in the next update.<br />
<br />
For now, heres the 145, I'll post more soon:<br />

However my 50-60 hour a week job, with a lot a travel, is slowing progress down quite a bit. Since it's a great job in a company whose business is growing I'm very fortunate. The past few years haven't been good for many people.<br />
<br />
The local shooting range that closed in February is still being refurbished in late May, that's another twist to getting shooting time.<br />
<br />
However, I'm still testing, casting, shooting and measuring results and will continue to publish it all right here.<br />
<br />
Currently my Rossi 357 lever action is loving the Group Buy Keith's. They are the long "as Keith designed them" version. Loaded in the crimp groove in 38 special brass, over 12.5 grains of 2400, this is a very nice magnum load, with excellent accuracy.<br />
<br />
Using the 38 special brass, the OAL is actually longer than what the Lyman Cast Bullet Handbook specifies for 357 brass. With 1,500 38 special cases on hand, it makes good sense to use them. Just be careful they never get loaded into a 38 special rated gun.<br />
<br />
Have fun shooting tight groups with your 357 magnum!Unknownnoreply@blogger.com5tag:blogger.com,1999:blog-2841706087367673439.post-65641822034702429462012-03-31T18:40:00.000-04:002012-03-31T18:48:02.525-04:00357 Lever Rifle-Crimp Test the Rifle FCD & Ladder Test 2400 - Plain Base and Gas Checks<span style="font-family: Verdana, sans-serif;">For some time I've wanted to test a custom Lee rifle Factory Crimp Die. Now that there are two new bullets designs in the works, it has to be done before proceeding with them. The purpose is to determine if these new design needs a crimp groove for the lever rifle or not. Conventional wisdom says yes, this crimp die however, says no. </span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">The 125-RF likes to be loaded long (1.597-1.600), with the crimp below the crimp groove and right on the middle band. That makes it a great test bullet for the rifle FCD. It makes sense the collet style crimp die (this is not the pistol FCD, it's completely different), could be highly effective in the lever action. This die is available from Lee as a custom order, or from Ranch Dog who stocks them in house. The can both be found via Google. These FCD's will not work on 38 specials, the cases aren't long enough.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">In the lever rifle's magazine, the firm grip prevents the bullets from being pushed further into the case. Even with max magnum loads there is no concern of a dangerous high pressure situation due to compressed case volume.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">Also, in the chamber, a bullet like the 358-125-RF can be loaded enough to bump up against the rifle's throat. This is proving to be the most accurate OAL so far.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">There's no reason this won't work just as well in a revolver too, but that's beyond the scope of this test. Conventional crimp groove bullets can be loaded long. But not having the groove in the way makes fitting the bullet to a gun easier, quicker and cleaner.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">The rifle FCD is adjusted to touch the shell plate on the press. Adjusting it down further, the shellplate drive a inner slide up into the die, forcing the four collets to close in and crimp the case mouth. This picture shows a rifle bullet extending through the die, and the four collets crimping right on the case mouth.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />

<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">The 357 bullets I'm using don't extend through the die like that, but has the four collets further down in the die body. </span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">I wanted to show the difference in the standard roll crimp and the rifle FCD crimp. In the following picture, the first bullet is the standard roll crimp, the second pictures show a rifle FCD crimp adjusted 1/2 turn, and the third picture shows a rifle FCD crimp adjusted 3/4 turn.</span><br />

<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">It's tough to tell the differences, but it's the best shot I was able to get. I noticed that the third case has a split mouth... not good. If you click on the picture is will expand, maybe you can make out the differences.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">The following pictures show test groups, at 25 yards, rested, with the iron sights on the lever rifle. It's the longest distance available, so that's what I use. To better indicate the differences, each group is 10 rounds.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">These test are using the Lee 358-125-RF over 5.4 grins of Unique. An extremely accurate load, and a personal favorite.</span><br />

<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">The best result is with the rifle crimp die adjusted 1/2 turn.</span><br />

<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">In the final analysis. When crimped directly on the bullet and not in the crimp groove, the rifle FCD is the most accurate. Adjusted 1/2 turn, for non-magnum loads. The rifle FCD may work just as well using a crimp groove, it just isn't part of this test.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">Now, let's take a look at ladder test results using this bullet and Alliant 2400. In a previous post I covered the laddter test methodoloy. Basically using one loaded cartridge per powder charge, the idea is to find the two sequential charges that shoot the closest together.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">To add another element of interest, there are two ladder test. One with gas checks and one with plain base bullets. I'm able to make and seat gas checks on plain base bullets such as the Lee 358-125-RF. </span><br />
<br />
<span style="font-family: Verdana, sans-serif;">The numbers map to the charge, but they are different in each picture. I'll explain, first though, here is the gas check result:</span><br />

<div style="text-align: left;">
<span style="font-family: Verdana, sans-serif;">During the test, each whole gets numbered, the target reset and then the next round is fired. Because of that 7 and 5 are misleading in the picture. In reality the potentially most accurate charge from this test is between 5 and 6, at 15.5 grains. They are closest vertically, I just pulled number 6 to the right.</span></div>

<span style="font-family: Verdana, sans-serif;">Next up, the test result from the plain base bullets. Note, these are full magnum loads which produce no leading. It could be the low round count, or that gas checks aren't needed. The 16.3 grain load estimates out at 2,020 FPS. That's getting up there for a 357 magnum.</span></div>

<br />
<span style="font-family: Verdana, sans-serif;">It turns out that the potentially most accurate load is also 15.5 grains. That load produces and estimated 1,920 FPS in a 20 inch lever rifle. Pretty sweet. The 13.5 load is fun to shoot, the 15.5 has a bit more kick to it. Not painful, but a newbee to shooting may not enjoy it as much as 13.5 or the 5.4 grains of Unique.</span></div>
<div style="text-align: left;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div style="text-align: left;">
<span style="font-family: Verdana, sans-serif;">It's unclear so far if gas checks are needed, or helpful, for this bullet and load. The Rossi has a slow 30 inch twist that may offset the tendancy for these magnum loads to lead. If your lever action has faster twist rate, such as 16 inch, than your result may be different.</span></div>
<div style="text-align: left;">
<span style="font-family: Verdana, sans-serif;">These ladder test both used the rifle FCD with a 3/4 turn crimp applied. As I continue to shake all this out and refine this die, and 2400 charges, I'll post final crimp results. Right now when using the rifle FCD, it looks like the best setting is for custom die to touch the shell plate, then add 1/2 turn for non-magnum load or 3/4 turn for magnum loads.</span></div>
<div style="text-align: left;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>

New gun in the house!My new stainless Rossi is here, and it's one sweet rifle. Or more technically correct, carbine.<br />
<br />
For the new readers, this is my second Rossi. I sold my blue gun, and regretted it immediately. It had much of the action job recommended by Steve's Gunz (more later), a Rossi weaver mount and a 2x scope. Since 99.9% of my shooting is indoors, it's usually limited to 25 yards maximum. Off a rest it shot a best five round group of .18 inches. That's not a slam dunk, even at 25 yards.<br />
<br />
Now, let me show you the new gun!<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Rossi2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="266" src="http://i878.photobucket.com/albums/ab341/prgallo/Rossi2.jpg" width="400" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
It looks just as great on the other side too:<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Rossi1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="266" src="http://i878.photobucket.com/albums/ab341/prgallo/Rossi1.jpg" width="400" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
The round barrel Rossi's come predrilled and tapped for a weaver mount, which Rossi also manufactures. The holes are underneath the rear sight and make it easy to swap sights back and forth.<br />
<br />
I really liked shooting with the 2x scope on the old gun. However, I decided to keep iron sights on this beauty. It came with a brass beaded front sight, and a nice rear sight. There's no need to mess up it's lines with a scope. <br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Rossi3.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="266" src="http://i878.photobucket.com/albums/ab341/prgallo/Rossi3.jpg" width="400" /></a></div>
<br />
The rear sight looked good, but it was swapped out for a Marbles Bullseye rear sight.<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/RossiMarbles.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="400" src="http://i878.photobucket.com/albums/ab341/prgallo/RossiMarbles.jpg" width="266" /></a></div>
<br />
It's hard to make out the inner ring, here's how it looks:<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/BullsEyeSightFinal.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="137" src="http://i878.photobucket.com/albums/ab341/prgallo/BullsEyeSightFinal.jpg" width="320" /></a></div>
This is one fun sight! The open field of view helps to aquire the target. Your eye naturally centers the front sight in the center ring. It's not as precise as the scope off of a rest, but shoots better off hand.<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/bullseye028.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" src="http://i878.photobucket.com/albums/ab341/prgallo/bullseye028.jpg" /></a></div>
With my range closed for renovations, I have to trek quite a way to be able to shoot. But the temporary range has some 30 yard lanes. With the Marbles Bullseye rear and stock front sight, it is lot's of fun when shooting off-hand. <br />
<br />
This new gun came with a nice smooth action, and a great feel. However the Steve's Gunz ( <a href="http://www.stevesgunz.com/">http://www.stevesgunz.com/</a> ) DVD contains video for a step by step action job. This gun now has some light work done on:<br />
<ol>
<li>Trigger is lightened</li>
<li>Loading gate is lightened</li>
<li>Magazine spring shorten to lighten it</li>
<li>Left cartridge guide smoothed</li>
<li>Bolt bottom smoothed very slightly</li>
<li>Replaced the plastic follower with a metal one from Steve's Gunz</li>
</ol>
Carefully using a Dremel, these minor tweaks take 15-25 minutes. Not much time, but with a huge benefit. <br />
<br />
Two things to know about these Rossi Lever Action rifles. There are some tricks to getting them back together. If you haven't ever tried before, get the Steve's Gunz DVD. It's worth every penny.<br />
<br />
Also, keep an eye out for the loading gate. If it slides back, you will get jams. It must be adjusted to be "in" the gun and not flush. Believe it or not, lightening the magazine spring lessens the pressure on the gate and minimizes the chance of a jam. When the gate is right, it works like it's supposed to.<br />
<br />
The everyday - super accurate & fun target load is the proven Lee 358-125-RF, over 5.4 grains of Unique. Proven in the old gun, it's just a accurate and just as much fun in this gun.<br />
<br />
Though my range is still closed for renovations, I'll be working up some hotter, high velocity loads for this gun. There are two new bullet designs in the works. I'm unsure if the 110 grain gas check mould or the 150 grain gas check bullet will the test bed. Maybe both, over time. I posted an early draft 110 grain GC and tumble lube bullet several weeks ago. Here is the conventional lube groove version, which is another option in the works:<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/C358-110-RFV3.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="200" src="http://i878.photobucket.com/albums/ab341/prgallo/C358-110-RFV3.jpg" width="191" /></a></div>
<div class="separator" style="clear: both; text-align: left;">
Over a heathly dose of 2400 or H110, this promises to be one awesome varmit bullet. With velocity potential up to 2,300 FPS. It's still in design with a lot of work remaining before it becomes a reality. The other option is a 150 grain version:</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/C358-150-RF.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img aea="true" border="0" height="200" src="http://i878.photobucket.com/albums/ab341/prgallo/C358-150-RF.jpg" width="156" /></a></div>
<div class="separator" style="clear: both; text-align: left;">
The 150 grain version could be really something special! Both bullets are designed specifically for the Rossi. Using chamber casting alloy, I carefully made a chamber casting, then designed each bullet to match the measurements.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
They promise to be excellent bullets with a plain base too. With the Lee 125 and several 158 grain moulds so inexpensive, I'm not sure another low-mid velocity bullet design is needed. However all options are on the table. The only thing I'm 100% sure of is, I'll change my mind many more times.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
If you have a preference which should happen, post your comments. I'm always interested in what fellow casters / handloaders think.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
There are more immediate tests needed first though. They are designed to validate the effect of crimping and different dies with no crimp groove. Those results are needed before either of these will be given the green light. Getting custom moulds gets expensive and it all adds up rather quickly.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I'll be following up with those results shortly!</div>

<span style="font-family: Verdana, sans-serif;">The sign-up phase runs out at 5pm on Saturday, 2/25. It's a sweet bullet, designed like the Lyman long nose version. Check out the link on the right for more info.</span><br />
<br />
<strong><u><span style="font-family: Verdana, sans-serif;">357 Lever Action Tests & Results Coming Soon:</span></u></strong><br />
<br />
<span style="font-family: Verdana, sans-serif;">OK, I've been enjoying the heck out of a Rossi 357, 20 inch, carbine. The goal is to explore higher velocity loads. There are some very accurate loads already in my results-database. I'm changing gears a bit and will pursue pushing some 110 and 158 grain cast bullets. These very strong guns respond well to pushing things a bit. </span><br />
<br />
<span style="font-family: Verdana, sans-serif;"><strong>Pushing a 110 grain cast bulllet over 2,000 FPS is on the test agenda.</strong></span><br />
<br />
<span style="font-family: Verdana, sans-serif;">A new Rossi is on the way, if you haven't cast/loaded/shot one of these, see if you can get your hands on one. There are some tips to smooth them out a bit, that will be covered too.</span><br />

<span style="font-family: Verdana, sans-serif;">These will not be revolver loads, they are intended only for modern day, very strong, rifles. The M92 Rossi is one of them, and will be used for the load development.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">I'm really looking forward to ringing this out! Here's a preview of a 110 grain bullet still on the drawing board:</span><br />

<span style="font-family: Verdana, sans-serif;">It's reached a point that the usual Blog format is getting hard for readers to navigate around. A Table of Contents to make it easier to find a particular topic and post is in the works. This will be a big help in seperating the Revolver & Rifle specific topics.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">That is somewhat less exciting than a 2,000 FPS load, but worthy enough to mention.</span><br />

The 358-429 Keith<span style="font-family: Verdana, sans-serif;">UPDATE: The group buy is going very well. There are 8 people signed up as I'm typing this. I'm making a change to the minimum number needed, to 7. That means the buy will happen.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">I've decided to start a Blog based group buy for a custom Lee six cavity mould. I'm so impressed with the results from my mould that I thought this would be both fun and a chance for other 357 casters / handloaders to take advantage of this style mould. There aren't many places to get a Keith six cavity mould, as a matter of fact a custom mould is the only way I know of.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">There's a Blog Page that describes the planned group buy. It's a slightly different protocol than other group buys so please read through it. <strong><u>The link at the top of the right hand column will take you to the details.</u></strong></span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />
<span style="font-family: Verdana, sans-serif;">Comments, feedback and questions should be posted there as well.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span><br />

<span style="font-family: Verdana, sans-serif;">As always, have fun and shoot tight groups.</span>Unknownnoreply@blogger.com4tag:blogger.com,1999:blog-2841706087367673439.post-3074074306229743132012-01-21T20:27:00.000-05:002012-01-23T07:15:34.631-05:00Update on the New - Custom Lee 358-429 & Bullet Fit Tips<span style="font-family: Verdana, sans-serif;">Getting a new-to-me Taurus 669 at the same time as the new mould came in created a double learning curve. It's what I love to do, but it takes some time to develop great loads. Finally, here's more detail about my target load and some early results from a full magnum load.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">This Lyman styled six cavity mould is cut to my specs and drops soft alloy bullets over .360 inches. Just as I wanted.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">The Taurus has a conventional groove diameter of .357. It's throats are huge, at .3595 and .360. It's a good thing that mould drops some fat bullets! </span><br />
<br />
<strong><u><span style="font-family: Verdana;">Bullet Fit Tips</span> </u></strong><br />
<br />
<span style="font-family: Verdana, sans-serif;">The basic rule for shooting cast is for the throats to be bigger than groove diameter, whatever they actually measure is less important, in my opinion. If the throats are equal to the groove, the gun can shoot good, but it's not ideal. If the throats are smaller, it's a problem, the gun will lead, most of the time, and accuracy will be dissappointing.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">If you have some dead soft lead (sinkers work well), here's a quick way to check your revolver dimensions are OK:</span><br />
<ol>
<li><span style="background-color: white; font-family: Verdana, sans-serif;"><strong><u>Tap the sinker into the muzzle, no more than 1/8 inch</u></strong></span></li>
<li><span style="background-color: white; font-family: Verdana, sans-serif;"><strong><u>Grab it with pliers and pull it out</u></strong></span></li>
<li><span style="background-color: white; font-family: Verdana, sans-serif;"><strong><u>From the cylinder face, see if the "sized" portion of the sinker will fit into each throat</u></strong></span></li>
</ol>
<span style="font-family: Verdana, sans-serif;">If it won't fit, the throats are undersized and tight. This is not ideal and the throats may need to be reamed to fix the problem. Assuming the sinker fits, your gun is good.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">Here's how my bullets checked out, this becomes important later:</span><br />
<ol>
<li><span style="font-family: Verdana;"><strong><u>Unsized a bullet will not push through the throats of the Taurus</u></strong></span></li>
<li><span style="font-family: Verdana;"><strong><u>Sized to .360, with a Lee custom sizer, they push through with finger pressure, using a pencil</u></strong></span></li>
<li><span style="font-family: Verdana;"><strong><u>If they drop through, they are to small. My Lyman .360 trims them a little to much, they drop through and they lead.</u></strong></span></li>
</ol>
<span style="font-family: Verdana;">I tried my favorite tumble lube recipes, including Johnson's Paste Wax and Alox, and nothing worked. More about lubing later with each recipe.</span><br />
<br />
<span style="font-family: Verdana; font-size: x-small;"><em>Note: If you want, you can slug your barrel and throats and measure the slugs with a micrometer, the basic rule to prevent leading is for bullets to be +.001 or +.002 over groove size. I've found that helps avoid leading, however often isn't the most accurate. Using the simple approach above works as well, in most cases.</em></span><br />
<br />
<span style="font-family: Verdana;"><strong><u>3.5 Bullseye Target Load</u></strong></span><br />
<br />
<span style="font-family: Verdana, sans-serif;">The 3.5 grain Bullseye load is still tops for a light target load. I was suprised to some degree when this bullet like to be loaded short. In 357 revolvers the vast majority of great bullet/load combinations are with a long OAL. Pushing the bullet as far into the throat as possible has become almost second nature. Loading a 358-429 so the nose is .005 from the cylindar face has proven to be a good starting point, backing it down from there. Typically a 358-429 has performed at it's best loaded 1.620-1.630, in my guns. Cylinders lengths vary a bunch, so your revolver may like a different OAL. In this case, it doesn't seem to matter.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">I always try a few loads loaded short, or near the minimum length for the given recipe. The Lyman Cast Bullet Handbook list 1.553 as the minimum. This load really came alive at 1.560 with a light to medium crimp. Very accurate, and a great load that anyone can shoot. At least in a 6 inch revolver, it does smooth out the recoil.</span><br />
<br />
<span style="font-family: Verdana;">This load shoots best with a pan-lubed & unsized bullet. They are over throat size an do not even push through the throats.</span><br />
<br />
<span style="font-family: Verdana;">So the target load likes a short OAL, an unsized fat bullet that is over throat size and a light crimp. Another surprise to me is that 700X was outdone by Bullseye, as they say: It is what it is.</span><br />
<br />
<span style="font-family: Verdana;"><strong><u>12.7 H110 Magnum Load</u></strong></span><br />
<br />
<span style="font-family: Verdana;">The long OAL 358-429's liked 13.5 grains of H110, loaded short this bullet and gun really like 12.7 grains, with a heavy crimp. It's a nice, big load, that shoots to the same point of impact, time after time. I admit that after shooting a while I have to work to avoid flinching.</span><br />
<br />
<span style="font-family: Verdana;">This full-house load works the best, still loaded short with the same 1.560 OAL, but with a heavy crimp. Pan-lubing and then sizing with the custom Lee nose-first .360 sizer proved to be the most accurate combination. This load likes the bullet to push through the throats with finger pressure. Use a pencil to test your bullet / throat fit. I suggest trying throat size and over-throat size bullets to see what shoots best in your revolver.</span><br />
<br />
<span style="font-family: Verdana;"><strong><u>In Conclusion</u></strong></span><br />
<br />
<span style="font-family: Verdana;">So far, this magnum load likes a short OAL, a Lee sized bullet (finger pressure to get it through the throats) and a heavy crimp. What else?</span><br />
<br />
<ul>
<li><span style="font-family: Verdana;"><strong><u>An old trick: So just as I'm thinking this is as good as it gets. I decided to lube both grooves in the bullet. The lube groove, and the crimp groove. Loaded short, it's fully covered by the brass, so why not.</u></strong></span></li>
<li><span style="font-family: Verdana;"><strong><u>Wow, this shoots even better. So let me add a lubed crimp-groove to the list of what works for this bullet, in this revolver.</u></strong></span></li>
</ul>
<span style="font-family: Verdana, sans-serif;">The Bullseye target load also likes the short OAL with an unsized bullet, pan-lubed in only the bottom lube groove and a light or medium crimp. The medium crimp shoots cleaner and is just as accurate, it's perfect for the range.</span><br />
<span style="font-family: Verdana;">There will be more pictures coming, so stay tuned as I continue to ring this combination out. Have fun shooting those tight groups!</span><br />

Good question. In my opinion there are a few criteria:</span><br />
<ol>
<li><span style="font-family: Verdana, sans-serif;">The bullets must be capable of less-than one inch groups. Shot at 25 yards off a sandbag</span></li>
<li><span style="font-family: Verdana, sans-serif;">To raise the bar, a magnum load must group less than one inch with iron sights, and</span></li>
<li><span style="font-family: Verdana, sans-serif;">A light target load must group less than one inch, with iron sights</span></li>
<li><span style="font-family: Verdana, sans-serif;">It doesn't lead the barrel</span></li>
<li><span style="font-family: Verdana, sans-serif;">The mould must cast consistently from cavity to cavity</span></li>
<li><span style="font-family: Verdana, sans-serif;">The mould shouldn't cost more than a car payment</span></li>
</ol>
<span style="font-family: Verdana, sans-serif;">Those are the criteria, from the most important down to the very important. Bullet design is critical for each of these, mould design beyond the cavity is an important secondary factor. The results on target, measured by calipers are the deciding factor. It's all about the groups.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">After casting, loading, testing, shooting, measuring and recording the results of over 30,000 357 magnum cast bullets: <strong>The Keith 358-429 design is the clear winner.</strong> That sounds like good news, and it pretty much is. The problem is, there a many flavors of this old design, and they aren't all equally effective, either on target or on the wallet.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">Three of the best and my favorites, in no particular order, are:</span><br />
<ol>
<li><span style="font-family: Verdana, sans-serif;"><strong>NOE 358-429</strong> - a semi-custom mould, available as a group buy, so if a buy is going on you can get one. Available is two cavity aluminum, five cavity alumunum, and I think four cavity brass.</span></li>
<li><span style="font-family: Verdana, sans-serif;"><strong>Lyman 358-429</strong> - a standard mould, made of a soft steel and lead alloy, in two or four cavity versions. In the past several years they have been cut to drop small undersize bullets. This is a big frustration as the design is superb.</span></li>
<li><span style="font-family: Verdana, sans-serif;"><strong>Mountain Molds Custom</strong> - you create the design using the website, the three cavity mould is first rate and one of the finest I've ever cast with. So you can't just order one of these, it takes work to figure it out. But they make great bullets. I've posted the specs I used in a prior post if you are interested.</span></li>
</ol>
<span style="font-family: Verdana, sans-serif;">If you read my older posts, then you know that the Lee TL 358-158 SWC is also an excellent shooter, but it leads in many guns. If it shoots in your revolver without leading and loosing accuracy after 50 - 100 rounds, it's a great deal. The leading is the only reason it isn't at the top of the list.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">There are other 358-429 moulds that are excellent, they all range in price from $84 for a four cavity Lyman to $120 - $170 for a three or four cavity custom or semi-custom mould. </span><br />
<span style="font-family: Verdana, sans-serif;"><strong>However, I wanted a great casting six cavity mould that met all of the criteria above. I now have one.</strong> Based heavily on the Lyman design, with some changes, I sent my design to Lee Precision as a custom order. Not cheap, it cost $205 when everything is all said and done. But the bullets are the best of the best.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">A Lee custom mould looks just like their standard mould, from the outside.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Lee-six-cavity.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="272" rea="true" src="http://i878.photobucket.com/albums/ab341/prgallo/Lee-six-cavity.jpg" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">The bullets from the 358-429 Lee custom mould all drop larger than .360. As I've written about before, these fatter bullets have consistenly outperformed thinner bullets.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">Using my favorite soft alloy of 98% lead and 2% solder (lead free), the Lee custom bullets drop at 178-179 grains, so I round up and call them 180's. Wheel weights are about three grains less. They took some load development for my revolver, just as it would for your revolver.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">Here are a few from my first casting run:</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/100_2379.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="298" rea="true" src="http://i878.photobucket.com/albums/ab341/prgallo/100_2379.jpg" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">I'm loving these, here's one more look:</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Picture003.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="308" rea="true" src="http://i878.photobucket.com/albums/ab341/prgallo/Picture003.jpg" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">Load development and results using my new-to- me used Taurus 669 are outstanding. I'm lovin' shooting this gun:</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Taurus-669.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="266" rea="true" src="http://i878.photobucket.com/albums/ab341/prgallo/Taurus-669.jpg" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">It does have large throats, so your revolver may shoot best after you refine my recipes (coming after load development is complete). For a light target load, 3.5 grains of Bulleye is a top perfomer. For now, this is what is possible at 25 yards, rested, iron sights:</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/100_2385.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="266" rea="true" src="http://i878.photobucket.com/albums/ab341/prgallo/100_2385.jpg" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">I can't shoot six rounds, with iron sights, without pulling one. I think you get the idea, the five round group measures .8 inches, center to center, so far.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">The load development and refinement is going so well that I'm thinking of offering it as a group buy on eBay or other online marketplace. To get a custom mould from Lee is $205. At $150 it would be a great value, a custom six cavity 358-429 that if full size, and shoot light and heavy loads. But that wouldn't meet the criteria... I believe it can be done for less than $100.</span><br />
<br />
<strong><span style="font-family: Verdana, sans-serif;">Stay tuned for load development results! I'm loving this bullet!</span></strong><br />
<br />
<span style="font-family: Verdana, sans-serif;">Shoot safely, and shoot tight groups.</span>Unknownnoreply@blogger.com13tag:blogger.com,1999:blog-2841706087367673439.post-84932325194717023762011-12-13T22:15:00.000-05:002012-01-10T21:28:45.940-05:00Going Back to Taurus, With a Used 669 6 Shot! Switching up Moulds by Selling My Best!<span style="font-family: Verdana, sans-serif;">Accuracy claims between owners of different revolver brands is a contentious topic. The owners of lower cost guns hope they are as accurate as the known "good performers". Such as a Dan Wesson, Ruger Blackhawk or S&W. Since I've been testing and measuring the accuracy, I've used a Taurus 66 6 inch, a Dan Wesson 6 inch and a Ruger Blackhawk 6.5 inch. I also shoot a GP100 and S&W 686 at the range, just to flush out some of the better known brands.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">Accuracy at 25 yards, rested and measured with calipers to .01 inch tells me that they can all shoot equally well. OK, not exactly all of them. The Blackhawk and Taurus are tied for the most accurate with a very slight advantage over the others. Slight means within .2 inches, which is way beyond my abilitiy and within the area of shooter error. But the difference in measurement does exist and seems to persist and be repeatable.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">If you spent big bucks on your 357 revolver and just love it, that's perfect. If you spent less and just love it, that's perfect too. An $800 or $1,200 revolver is one great revolver, it just doesn't outshoot a $400 revolver. I haven't tested a Freedom Arms, because they are out of my price range. They may in fact be more accurate, but I'll probably never know for sure. </span><br />
<br />
<span style="font-family: Verdana, sans-serif;">I decided to change things up a bit and sold the Blackhawk.</span><br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">It was a good test bed and a fun gun to shoot. In it's place is a used Taurus 669, according to the Taurus serial number lookup it was manufactured in 1992. I want to see how it performs, compared to the other guns. If you are looking for a good buy, the post mid-1980's Taurus are well made pieces.</span></div>

<span style="font-family: Verdana, sans-serif;">This fine looking revolver cost me $269, plus the usual costs for shipping and FFL fees (the Federal Transfer Fee for those outside the USA). I've had it for a few days, and have learned a lot about what cast bullets it likes, and what it doesn't like. Full house loads of 180 grain Keith bullets, over 13.5 grains of H110, rested at 25 yards suprised me with this first group:</span></div>

<br />
<span style="font-family: Verdana, sans-serif;">Pretty good, especially with the iron sights. Actually, that's exellent! This Taurus, like the prior Taurus, doesn't respond well to loads using Unique powder. But is warming up to faster powders like 700X and Bullseye.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">More results wil be coming, after a brief Christmas break. That's not all that's changing around here. To start the new year off, I took the top four bullet moulds:</span><br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/BulletKings.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="230" oda="true" src="http://i878.photobucket.com/albums/ab341/prgallo/BulletKings.jpg" width="320" /></span></a></div>
<br />
<span style="font-family: Verdana, sans-serif;">They have all been sold on eBay. The lapped Lyman 358-477, the lapped Lee TL-358-158 SWC, the Lyman 358-429 and even the new custom made Mountain Molds 358-429 180 grain Keith. It was the single best performing bullet in the Blackhawk. It wasn't around when I had the Taurus 66 so there's no direct comparison available.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">On the way, hopefully soon, is a custom 6 cavity Lee mould. I produced the design and they are cutting the mould. It'll basically be a 6 cavity version of the 180 custom Keith. It's expensive, but the best bullet I've shot in any gun to date. With the custom tooling it's costing $205. That's almost as much as my gun!</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">I plan to work with that new mould, and to dust off a 200 grain SWC from NOE. One of my favorite mould manufactuers. These heavies have been consistently outperforming the lighter bullets, and are the best that I've found. Working up a lighter load, and more testing to refine the full house loads will be the priority for next year.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">The 669 has big throats, and likes the .360+ bullets unsized, so I'll walk you through how I determined that fact, and other key steps to getting superb accuracy. Casting and handloading a 357 magnum can produce terrific highly accurate results. But not every revolver will shoot lead effectively, that's an unfortunate truth.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">There will be a few brief diversions to the Rossi, 20 inch 357 magnum lever action carbine too. Shooting loads of 700X and a Lee 358-125-RNFP, it is something to behold. </span><br />
<br />
<span style="font-family: Verdana, sans-serif;">More info and test results are coming soon! Shoot well and have fun at the range.</span>Unknownnoreply@blogger.com2tag:blogger.com,1999:blog-2841706087367673439.post-61440041910093404502011-11-18T19:29:00.001-05:002011-11-20T09:33:56.643-05:00The Affect of a Nose Punch on Accuracy - 358-477 Lyman & 358-429 Keith<span style="font-family: Verdana, sans-serif;">The Lyman 358-477 is one of the most accurate moulds for my 357 6.5 inch Blackhawk. For my 357 20" Rossi lever action carbine the 358-477 bullets won't even group at this point. That just doesn't seem right, Thinking through the different accuracy tests ant the results (over the past several years and tens of thousands of bullets), I knew this bullet shot best when sized in a custom Lee sizer and tumble lubed. The Lyman 450 sizer produces bullets that perform almost as well in the Blackhawk, but both lube approaches just failed in the Rossi.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<ul>
<li><strong><span style="background-color: white; font-family: Verdana, sans-serif;">I decided to try some tests with different nose-punches, to see if the 358-477 would at least group out of the Rossi.</span></strong></li>
</ul>
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<ul>
<li><strong><span style="background-color: white; font-family: Verdana, sans-serif;">If it worked, I would then run the same test on 358-429 bullets from my new Mountain Mold (see prior posts for more details).</span></strong></li>
</ul>
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">The primary rationale for a nose punch test is that the nose first sizing of the Lee die pumps out "well-centered and square" bullets more often than the Lyman. Could a loose fitting nose punch in the Lyman cause the bullets to be less accurate? It's an easy enough test. Here's the lineup of nose punches with a 358-477:</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />

<a href="http://i878.photobucket.com/albums/ab341/prgallo/NosePunch358477.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" hda="true" height="266" src="http://i878.photobucket.com/albums/ab341/prgallo/NosePunch358477.jpg" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">The flat punch is my standard, it is widely accepted as affective so it made sense to use it. The deep fit / snug fit middle punch came with a NOE mould. It also makes sense to give it test and see if there's any improvement in the Rossi. The RCBS sits in between, but is loose fitting with not much more support than the flat punch. I included here as a visual reference to show just how deep and snug the test punch is.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">I loaded up test loads using 5.4 grains of Unique, using the deep seating NOE punch and headed to the range. Using the same 2X scope as before, I didn't expect much. This exact same load was a dissapointment every time I shot it in the Rossi. So how did it do? Here are the two best groups, the single flyer in each is shooter induced (sorry about that, I'm only human after all... with no Ransom Rest):</span><br />

<div>
</div>
<span style="font-family: Verdana, sans-serif;">So much for low expectations. The bottom 4 shot single hole (above the dime, excluding the fifth flyer) measure .190 inches, center to center. That is the single best group I've ever shot. Ever.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">A quick recap: the 358-477, when sized with the Lyman & a loose nose punch, or the Lee, doesn't group from the Rossi lever action. There is no before picture, so just think "swiss cheese" and randomly placed holes. I change the punch to a deep fit / snug fit punch to see what happens. This bullet goes from zero to hero, unseating the Lee TL 358-158-SWC as the most accurate in the Rossi. WOW!</span><br />
<br />
<ul>
<li><span style="background-color: orange; font-family: Verdana, sans-serif; font-size: large;">The improvement comes from the bullet being </span><span style="background-color: orange; font-family: Verdana, sans-serif; font-size: large;">centered while running through the sizer, and </span><span style="font-family: Verdana, sans-serif;"><span style="background-color: orange;"><span style="font-size: large;">being very square and straight as it's sized.</span> </span> </span></li>
</ul>
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">It's time for the next step, how would this work with the beautiful 180 grain, 358-429 Keith bullets cast with my new custom Mountain Mold. First, the punch lineup:</span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">The flat punch produces good results with this large meplat bullet, with groups less than 1 inch, at 25 yards & off a rest. How does the deep fit / snug fit NOE punch affect accuracy. </span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">These are two different loads. On top is a 5 shot group with13.5 grains of H110. Very impressive, the real story is the bottom . It's a 4 shot group (I ran out of test bullets) and my very first revolver group less than .5 inch. That's pretty special in my book, rarified air IMHO. It is now the number one most accurate bullet and load, measuring .380 inches, center to center. WOW AGAIN!</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">These are spectacular results. The problem is, my one NOE custom nose punch isn't very helpful to you or anyone else. It doesn't help me either, with new bullet besigns in the future that need a different size punch.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">Luckily, I recently came across Keith Benedict and his unique nose punches. I've just order 4 for future use. He offers standard nose punches for a many calibers. What's so different about his "open" design punch:</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />

<span style="font-family: Verdana, sans-serif;">They are open so then can be filled with epoxy, or hot glue, and then form fitted to a specific bullet. That gives a deep fit / firm fit, every time, for any bullet. If the standard nose punch doesn't quite meet your needs, you can order one custom sized one.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">I'm not connected with Keith or his busness. This is the best solution I've found and need to pass the info along. You can contact him directly at </span><a href="mailto:keiththeperfessor@gmail.com"><span style="font-family: Verdana, sans-serif;">keiththeperfessor@gmail.com</span></a><span style="font-family: Verdana, sans-serif;"> and he will provide all the information needed. Including instructions. If you have a loose fitting nose punch, it may work with epoxy or hot glue, give it a try with what you have.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<div>
</div>
<span style="font-family: Verdana, sans-serif;">Either way, taking advantage of a deep fit / snug fit nose punch for maximum accuracy makes good sense.</span><br />

<span style="font-size: small;">For folks that can't seem to get a 358-429 mould that drops full diameter bullets, here is one great solution.</span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">The last couple of Lyman 358-429's that I bought cast .356-.357 bullets. Too small to be lapped, especially since they are made of a steel/lead material. It's too difficult to lap them to .3604 or so, which my guns like sized to .360.</span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">My NOE mould 5 cavity is awesome, but it's only run once a year so you can't order one right now! There are a few places that can help you out. Mountain Molds is one of the most unique, with an online design tool. There are ton of options and measurements that can be changed to make the mold you want. If the tool can draw it, Mountain Molds can make it.</span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><span style="background-color: orange;">My new custom 358-429 shoots as great as bullets cast from the NOE and Lyman moulds. It's one of the top bullets, one of the most accurate and it loves magnum full-house loads. It is 100% of everything I had hoped for and expected. I did tweak it for a wider meplat, it's a beefed up Keith! </span></span></div>
<div style="font-family: Verdana,sans-serif;">
<br /></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">Before I get to the details, here's a quick look at the top 3 designs that I've found:</span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: center;">

<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: center;">
<br /></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">A quick review of these great bullets, from left to right:</span></div>
<ol style="background-color: orange; font-family: Verdana,sans-serif;">
<li><span style="font-size: small;">Lyman 358-477: The 150 grain mould came already dropping nicely sized bullets. To get exactly the size I want, with my soft alloy, took some minor lapping. With the softer, and also heavier alloy, it drops 4 160 grain bullets. I shoot a bunch of these every month.</span></li>
<li><span style="font-size: small;">The Lee TL-358-158-SWC was easier to lap, since it's aluminum, unlike the steel/lead construction of the Lyman. This now drops at 168 grains, with the soft & heavy alloy. The Ruger Blackhawk leads at the lands, unless it gets a heavy dose of Liquid Alox. It's incredibly accurate.</span></li>
<li><span style="font-size: small;">The last two are both 358-429 bullets. I didn't have a NOE handy for this picture, because I shot all that I had on hand!</span></li>
<ol>
<li><span style="font-size: small;">This is the Lyman bullet. It's a little longer than the NOE, but they are similar. I used this as the model for my custom Mountain Mold.</span></li>
<li><span style="font-size: small;">This is the bullet from the Mountain Mold. I wanted a little bigger meplat, specified it using the online tool, and it's right on the money. It fits the Blackhawk really well, and even cycles in a Rossi Lever Action. A few more thousanths and it probably wouldn't. You can decide how big you want your meplat. The orignal Keith was (I believe) .250, this one is also .250.</span></li>
</ol>

<div style="font-family: Verdana,sans-serif;">

<span style="font-size: small;"> It takes some learning but in no time you will be used to the interface. It's a lot of fun and very easy considering that you are actually designing a bullet mould.</span></div>

<span style="font-size: small;"><br /></span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">Let me say, this mould is awesome. Mountain Molds will cut either one, two or three cavity moulds. Check out the absolutely wonderful sprue plate. If you enjoy casting as much as I do, it's easy to get excited over the Mountain Mold design. It's thick, it cuts great and the recessed holes making casting a breeze. I can cast more bullets with this 3 cavity than most other 4 cavity moulds.</span></div>

<span style="font-size: small;">Nice looking vent lines and a big block help make this cast so well. Note the block size in the design tool screen shot above.</span></div>

<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">Attention to detail is evident in the alignment pins, and the overall look and feel, This mould is a joy to cast with. Now you can get any bullet you want, without having to waiting for group buys. Modeling a design after a known bullet can get you started quickly.</span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;"><br /></span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">One of the more important decisions is the diameter. You must decide if you want the specified diameter to be the maximum or minimum, or in the middle of the tolerances. I choose for .360 to be the minimum. Since I size and lube, and my guns love fat .360 diameter bullets, this works. </span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;"><br /></span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">I'll be working up additional design specs in the near future, stay tuned for those results.</span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">At the beginning, I was concerned that the bullets from my custom mould would not be as accurate as I demand and expect. After all, testing thousand of rounds, testing endless alloys, unending moulds, lapping, sizing, lubes and alloy temps, it all resulted in a finely tuned set of a few excellent moulds. </span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">Not to worry. The design is close enough to the model design, which is proven. Then adjusted for the diameter my guns want, with my alloy. It surpasses the accuracy and performance of the others, to make it into the top three bullet moulds. Gotta love it!</span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;"><br /></span></div>
<div class="separator" style="clear: both; font-family: Verdana,sans-serif; text-align: left;">
<span style="font-size: small;">I hope this provides another way to get that bullet you really want. Now, if you design something your gun doesn't like to shoot, that's another story. Stay close to a proven masterpiece (the 358-429 Keith in this case) and tweak to suite your guns, and you'll be one happy casting handloader.</span></div>

Any Difference in Accuracy?<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">The benchmark for accuracy remains at 25 yards, off a rest. Sometimes with iron sights, other times with various scopes that I seem to buy and sell off. I also own and have owned casting and reloading equipment from various manufacturer. Looking at what I have on hand: I load 38 Special with Lee Dies (3 die set) and Dillon Powder Measure. 357 Magnum is loaded with Dillon Dies and Dillon Powder Measure. Each setup is on it's own toolhead, which makes swapping them out a snap.</span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">I wanted to see if a RCBS lock out die would work into my handloading process for both 38 and 357. It takes one of the 4 holes, leaving 3 stations for the Lee 3 die set (since I had it already). Seating and crimping at the same time in the last station. Before deciding to make the switch, I wanted to see if the Lee Die setup produces ammo with the same accuracy as the Dillon.</span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">It's not exactly and apples to apples comparison, but my goal was to free up a hole for the RCBS. In an earlier post I noted that the Lee FCD can cause problems. So I'm not really interested in doing additional tests with a Lee 4 die set, which wouldn't free up a station anyway. My recommendation is to not use the FCD for oversize cast handloading, which is 100% of what I do. It's great for jacketed bullets, just not cast.</span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">First, the press and other gear, for handloading 357 magnum and 38 special (for my snub-nose) I really like a Dillon 550:</span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div class="separator" style="clear: both; font-family: Verdana, sans-serif; text-align: center;">

<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">FYI, I don't have the roller handle or the fancy base. But this is one awesome press. It is a manually indexed progressive. After owning turret presses, and several auto-indexing progressives I've decided this is the way to go. Very safe, very quick and easy to do a mid-course correction. </span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">A Dillon 3 die set doesn't include a powder/expander die. They take a little more time to set than the Lee dies, but are easy to clean. They come apart and go back together without having to unscrew and reset them. </span></div>
<div style="font-family: Verdana, sans-serif;">

<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">The powder dies comes with the toolhead, and is one size fits all. The toolhead with powder die is pretty inexpensive:</span></div>

<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">Each caliber takes a specific powder funnel. The one on the left is for most pistols, it expand the brass as well a flares the case mouth. The same one fits 357 and 38 special, it's pretty convenient.</span></div>

<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">That is what I used to handload the "Dillon" bullets. I removed the dies and added this equipment from Lee:</span></div>

<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">A Lee carbide 3 die set. It costs less than half of the Dillon dies, and includes a powder through expander too. Really a great deal and price point.</span></div>

<span style="font-size: small;">In place of the Dillon Powder Measure, I used the Lee Pro-Auto Disk. It cost about half of the Dillon setup, and is another great deal. The disks make finding a known load quick and easy. It's surprisingly precise too.</span><br />

<br />
<span style="font-size: small;">I tested, off a rest with my 6.5 inch Blackhawk,<span style="background-color: white;"> with a 2x scope, using the 358-477 bullets and 3.5 grains of 700X. My most accurate load.</span></span></div>

<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">My first test, at 15 yards, showed no difference in accuracy. I shot many groups, sometime the Dillon was better, sometimes the Lee group was better. They were all close.</span></div>

<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">The difference should be obvious, if not clouded by my poor photographic skills. On average, the Dillon groups are in fact smaller. </span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="background-color: cyan; font-family: Verdana, sans-serif;">
<span style="font-size: small;"><u><b>At 25 yards, Dillon handloads range from .25 to .5 inch smaller, 80% of the time.</b></u></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="background-color: cyan; font-family: Verdana, sans-serif;">
<span style="font-size: small;">After adjusting seating and crimp dies to get the most out of the Lee's, that's the bottom line. At 25 yards, the Dillon loaded ammo begins to show superior accuracy.</span></div>
<div style="background-color: cyan; font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="background-color: cyan; font-family: Verdana, sans-serif;">
<span style="font-size: small;">If, like me, you want the most accurate handloads, at 25 yards, Dillon wins this one. If your goal accuracy at shorter distances, Lee will save some money. </span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">So, the RCBS isn't working into the my reloading process. It was really a thought about "additional" safety. The standard Dillon setup isn't unsafe in any way, to the contrary, it's a great design all the way around. Since I'm comfortable with the Dillon, and it's more accurate, that's what I'll continue to use for my daily handloading.</span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana, sans-serif;">
<span style="font-size: small;">Next up, I recieved my mould from Mountain Moulds. I used their great online design tool in an attempt to get a Lyman styled 358-429, that drops at a full .360 diameter. I've cast with it, and shot my initial test groups. Let me say, this is one fine mould. Details will be coming...</span></div>
<div style="font-family: Verdana, sans-serif;">

It is great to get a new Lyman Mould that drops decent size bullets. After lapping, this gem of a mould is now being added to Favorite Moulds. The 6.5 inch Blackhawk is loving these!<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
Using a Lubrisizer with Darr Lube, NRA or Carnauba Red leaves a clean shiny barrel. 200 rounds and no cleaning needed! Johnson's Paste Wax as a tumble lube, a personal favorite, also produces great results. After 100 rounds there may be a slight hint of leading, the Blackhawk likes to lead more than the Taurus.<br />
<br />
Use a bronze brush wrapped with a swatch of copper Chore Boy and clean any trace of leading, in less than 30 seconds. There is no accuracy loss after 100 rounds, but I do need to test after 200 rounds. I'll get some measurements with 5 shot groups, but 1 ragged hole with 10 rounds at 25 yards is excellent.<br />
<br />
Any time the barrel can be completely clean in a minute or two, that's good. Less than one minute is great. Needless to say, I'm now using a custom .360 Lee sizer and then tumble lubing with the JPW. There are posts about <a href="http://357shooter.blogspot.com/2011/05/tumble-lube-for-your-357-magnum.html">Tumble Lubing</a> if you are interested. There is also a post on <a href="http://357shooter.blogspot.com/2011/05/lapping-mould-what-to-do-if-your-mould.html">how to lap a mould</a>. <br />
<br />
A four cavity Lyman Mould, made out of soft steel & lead alloy, can cast a bunch of bullets quickly. It is a real joy to use. A little heavy, but holds heat well and drop the bullets easily. I enjoy casting with this mould, and then handloading & shooting these bullets.<br />

</tbody></table>
<span style="font-size: x-small;">*5.1 of 700X was with the 168 grain bullet, not for use with the 178 grain lapped version. Check all loads with your reloading manuals and recipes to ensure they are not over-max-pressure.</span><br />
<span style="font-size: x-small;">**The 358-477 had bad accuracy in the Rossi M92 Carbine. After several tests I've concluded it isn't a match with this gun. </span><br />
<br />
Getting a 358-477 mould and that drops decent sized bullets can be hit and miss. But when it's a hit, it's very good.<br />
<br />
There will be another follow-up, testing this bullet with H110, with Magnum loads.<br />

I ordered a new 358-477 from Cheaper Than Dirt. What a great surprise! Dropping nice size .3576 and .359 bullets with soft lead, as delivered from the factory. That's much bigger than the prior mould. Made of soft steel (steel and lead alloy) the four cavities create a pile of great looking bullets in no time flat.<br />
<br />
My guns shoot .360 soft alloy bullets better than anything else. That soft alloy cast smaller than the "spec" alloys used by the mould manufactures, as a result I expect to have to lap them at least some. It took some time to get the go through that entire process. Previously described in detail, here's an overiew:<br />
<br />
<ol style="background-color: orange;">
<li>Before first use, heat cycle the mould, 3 times at 400 degrees</li>
<li>Strip the sprue plate and screws off</li>
<li>Heat the mould and alloy</li>
<li>Pour through some nuts, one over each cavity</li>
<li>Cool and measure, if all the cavities are full size (.3604 across the seam) it's done. Wash up, and the mould is ready</li>
<li>Lap with 220 grit Wheeler Lapping Compound (from Midway)</li>
<li>Cool down & wash with Dawn</li>
<li>Go back to step 3</li>
</ol>
It takes a few hours, and is well worth the effort. The lapped mould drops .3604 diameter, 160 grain BHN 8 bullets effortlessly. <br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Lyman358477.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="253" src="http://i878.photobucket.com/albums/ab341/prgallo/Lyman358477.jpg" width="320" /> </a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
Lubed with Darr lube, I loaded up a bunch of 357 brass with 3.5 grains of 700X. Shooting off-hand at 25 yards matched my best results to date, of any bullet. That includes the champ, a lapped Lee TL-358-158-SWC. The lapped 358-477 requires a shorter OAL than the usual. The Blackhawk can handle these at 1.600, just barely. There is a little resistance when rotating the cylinder as they fit the chamber "snug".<br />
<u><b><br /></b></u><br />
<u><b>Lube for Convention Lube Groove Bullets</b></u><br />
<br />
I've written a lot about using Alox and JPW for bullets with tumble lube grooves. But that's not all that I use, by any means. For conventional grooves I also like to use a Lyman Lubrisizer and a .360 sizer. It pumps out well sized and very round bullets very quickly, that may be worth a post sometime. The conventional lubes of choice are Darr (homemade), NRA & Carnauba Red, from White Label lube. Their 2500+ looks like a good one to try too, much like the NRA, but not as soft. These lubes, and many others from other providers, are excellent-proven products. Look for a used 450 Lubrisizer and get lubing! A Star from Magma is a good way to go, if money is no object. I have a used Lyman 450, it works just fine.<br />
<br />
For loads that work with pure Johnsons Paste Wax, that remains a top favorite. It takes testing to determine if that works the best. For example, a Keith style bullet with a large deep lube groove doesn't work in my guns, with tumble lube. At least for full-house loads. I plan to test the 358-477 with JPW in the upcoming weeks.<br />
<br />
In closing on the 357-477, the Blackhawk is loving these with a light load. Heavier loads remain to be tested. A huge surprise is that the Rossi M92 20 inch lever rifle doesn't like these one bit. The Lee TL-358-158-SWC remains the king in the Rossi, at least for now.<br />
<br />
<u><b>Now, the 358-429</b></u><br />
<br />
I placed an order (Cheaper Than Dirt again) shortly after the great results with the 477 mould. I heated it up, cast some bullets, and with high exceptions began to measure them. What a let down, .3555 to .357 inch. After a couple of tries, I decided the micrometer wasn't lyin' to me.<br />
<br />
That's way to much lapping for me, even if it might work. I'm not sure it would. I really like the design of this bullet, so it was time to get creative. I measured and measured the 429 bullets. Once I had a good idea of the dimensions, it was time to go with a custom mould. I choose Mountain Molds, who has a nice oneline design tool.<br />
<br />
It took some time to get solid measurements for the nose, lube groove and driving bands. I ended up specifying a 175 grain bullet, the spec alloy being WW. That'll put my soft lead bullets closer to 178 to 180. The order was placed last night, here are the specs (you may have to click to be able to read the details):<br />

<br />
It takes a combination of measurements and much tweaking. But I believe it's close to the same measurements as the Lyman. Needless to say, I'll do a write on the the mould and the results at the range. I'm excited to have a custom design on order, even if I did make it as much like the Lyman as possible.<br />
<br />
Have fun at the range, more results are coming soon.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2841706087367673439.post-62868529510623686552011-09-03T19:50:00.014-04:002011-09-25T18:56:46.145-04:00Favorite 357 Magnum Bullet Moulds and Loads<div style="font-family: Verdana,sans-serif;">
<u><b><span style="font-size: small;">Overview</span></b></u></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">Which cast bullet and load shoots the best, most consistently? This is about 357 Magnums and how accurately they shoot. 25 yards off a rest & sandbags, measured with calipers, then logged and sorted is how I determine what gets included in the <b><a href="https://spreadsheets.google.com/ccc?key=0Ar4xSLouy2aUdElzVEZPbDMzOExacFBVbi1tUkZVZUE&hl=en&authkey=CKzluvMC#gid=0"><b>Most Accurate Bullet Moulds and Loads Table</b></a>. </b>It's a detailed list of data regarding the best and most accurate bullets. My favorite loads, the best of the best are highlighted later in this post.</span></div>
<div style="font-family: Verdana,sans-serif;">
<br /></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">Being limited to an indoor range 98% of the time is the primary reason for the distance limitation. Other indoor shooters often practice at 10 - 15 yards while outdoor shooters often shoot 100 or even 200 yards. With a 6 inch or longer barrel a 357 Magnum is surprisingly accurate at long distances.</span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;"><br /></span></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">Semi Wadcutters, Keith and non-Keith consistently out-shoot all other designs. When measured center to center, with calipers, that's the way the numbers stack up. Round-nose bullets, full wadcutters and lead-flat-nose (LFN) bullets all have their following, and their place. Measuring groups center-to-center produces a clear winner, the SWC.</span></div>
<div style="font-family: Verdana,sans-serif;">
<br /></div>
<div style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">For example, when shooting off-hand, a full wadcutter may shoot slightly bigger groups (we are talking tenths or hundredths of an inch) than a good SWC. But in Bullseye the wadcutter may outscore the SWC. Just because that discipline doesn't measure center-to-center distances. It scores points based on the wad-cutters bigger clean-cut-hole simply touching a ring. I hope this a good example of how measuring the accuracy in a different way can provide a different result. </span></div>

<span style="font-family: Verdana,sans-serif; font-size: small;">The 357 Magnum guns listed below are a 6.5 inch Ruger Blackhawk, a 6 inch Taurus 66 and a Rossi 20 inch Lever Action rifle. It's included for fun, which is what this is all about. These bullets and loads are what I cast and shoot all the time. 1,000 rounds a month total.</span><br />

<span style="font-size: small;">These two moulds have proven themselves as the most accurate and most consistent for a 357 Magnum. A few of the loads were found by doing a ton of testing. Shooting multiple 5 shot groups and thousands of bullets. The rest were found with using Ladder Testing: Incremental Load Development. That approach is detailed in a multi-part series previously posted in this Blog.</span><br />

<span style="font-size: small;">There are many of designs and moulds not listed. I've tested a ton of them. I'm often told that the newer breed of LFN style designs are more accurate than semi-wadcutters, you may hear the same. However, in a 357 Magnum, the SWC is the most accurate and most consistent design. Some of the new designs are accurate. However after shooting many groups, measuring and sorting the results, the SWC wins. The other bullets that I tested aren't listed because they are less accurate.</span></div>

<span style="font-size: small;">You, the shooter, have to do your part when shooting for groups. Even when using a sand-bag, or other rest, it takes practice and repetition. It's not a slam dunk to shoot groups less than 1 inch. Shooting off-hand, unsupported, is even much harder to do. The bullets and loads that shoot the best groups when rested, also shoot the best off-hand. Albeit with larger groups.</span></div>

Consistency and accuracy with a revolver at 25 yards, even off sand bags, is hard to achieve. I wish I could say I redid the 700X Ladder for the Blackhawk, and this time it worked. But I didn't redo the Ladder. I had some 3.5 700X loads handy, with the 2 X Alox with Mica (Extreme Alox in prior post) lube and shot this great group:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
Shot indoors, 25 yards off a sandbag rest, using the open iron sights on the Blackhawk.<br />
<br />
This is a favorite load from the Taurus 66 and Rossi M92 rifle. 700X didn't shoot in the Blackhawk at all, at first.<br />
<br />
In hindsight I suspect that the 700X Ladder missed this load because I flinched or made some other error. Maybe having worked out the lube & leading problem made the difference. So retest from time-to-time. Especially if you don't have much experience shooting off sand-bags or a rest.<br />
<br />
Technique makes a big difference and it is all too easy too influence the Ladder Test results. This is true no matter what approach is used to work up loads.<br />
<br />
<u><b><span style="background-color: orange;">Ladder Test - Incremental Load Develop continues to be my new favorite approach to work up accurate loads.</span></b></u><br />
<br />
Luckily for me I had some 3.5 - 700X loads handy to shoot a few groups. It could be that a Ladder Test with fast powders should use .2 grain increments. The .3 increments I used in the other tests has a much great impact on 3.5 grains of 700X than it does on 13.5 grains of H110. Food for thought and a suggestion when you work up a load with a Ladder Test.<br />
<br />
<b>H110 in a Rossi Lever Action Carbine:</b><br />
<br />
For fun I've included a picture of a 10 shot group from the 20 inch Rossi M92 Lever Action rifle. It's at 25 yards (max at my range) with the Lee TL-358-158-SWC (lapped) over 13.5 grains of H110:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
A load of 13.5 grains of H110 with a magnum primer and either the Lee TL-358-158-SWC or the Keith 358-429 is a great performer. Fun to shoot in a revolver and fun to shoot in a rifle too.<br />
<br />
Have fun refining your 357 Magnum handloads, the finest caliber of all. <br />

<a href="http://i878.photobucket.com/albums/ab341/prgallo/168-H110Group.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><br /></a></div>
It's been a few weeks since starting this series. Here is a review of the H110 Ladder test. If you haven't been following along, please go to Part 1 and start there, otherwise this won't make sense.<br />
<br />
First, the ladder test results using the Lee TL-358-158-SWC bullets, now dropping at 168-170 grains. I modified the mould by lapping it, which is described in a earlier post.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/H110-168-Ladder.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="280" src="http://i878.photobucket.com/albums/ab341/prgallo/H110-168-Ladder.jpg" width="400" /></a></div>
<br />
Based on this ladder, 13.5 grains is the sweet spot, now to test it out.<br />
<br />
Testing the 13.5 grain load: The test revolver remains a Ruger 357 Blackhawk with a 6.5 inch barrel, and stock open iron sights. Shooting groups at 25 yards, even off a sandbag rest is a challenge for me. I included a quarter as a reference, the target sizes are completely different in these photos, with this one being 1/2 the size of the ladder test picture.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/168-H110Group.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="388" src="http://i878.photobucket.com/albums/ab341/prgallo/168-H110Group.jpg" width="400" /></a></div>
<br />
I've started shooting off-hand (unsupported) and more rounds in each group for these tests. This is one great result, for me, the variance is all shooter induced. The iron sights make it difficult to shoot every round in a tight group, but I seem to be improving. Even though it might not look like it to some of the readers. <br />
<br />
The results of the tests have shown that the Ladder Test <b>WORKS</b>. At least in a longer barreled 357 magnum. I do plan a test with a 38 special snub-nose, but not as part of this series.<br />
<u><b><br /></b></u><br />
<div style="background-color: orange;">
<u><b>If you want to work up loads quickly and effectively use a Ladder Test. In one session, with as few as 5 rounds to 9 rounds, you can identify sweet spots with a given powder.</b></u> </div>
<br />
Refining the charge at the sweet spot is completely up to you, but I have yet to improve the cartridges accuracy beyond the test result. During this test, great loads using Unique and H110 were discovered for both bullets used. The Lee TL-358-158-SWC and the 358-429 from NOE, both are lapped. 700X was shown to not work in my Blackhawk (see Part 5 for more about 700X & fast powders in general), even though my Taurus 66 loved it.<br />
<br />
<b>Extreme Alox Described:</b><br />
<br />
The Blackhawk shot the TL-358-158-SWC accurately from day 1. However it starts to lead at 10-20 rounds and looses accuracy at 40 rounds. At this point, the bullet isn't a viable option for this gun. The leading is right at the start of the lands, extending 1/8-1/4 inch.<br />
<br />
I decided to see if it would ever shoot without leading this bullet, without fire-lapping the gun or modifying the gun in any way. I've gotten great results fire-lapping in the past, but it's not guaranteed to fix this problem, and once some metal is removed it can't be added back. So instead, I decided to test different way to lube with liquid Alox.<br />
<br />
First, the Lee instructions for a standard application leave a very thin coating of Alox. This is the proven and standard way to lube using liquid Alox. Since that didn't work, I went non-standard, so this Extreme Alox (my term for the process) is to address a problem. If you have a similar leading problem, give either of the two approaches a try.<br />
<b><br /></b><br />
<b>Extreme Alox 1:</b> The Blackhawk has no leading in any load with the 358-158 any more. By applying a heavy coating of Alox and Mica, it shoots everything from puff loads to full magnum rounds leaving a shiny barrel after 100 rounds. The steps to apply this heavy coating are:<br />
<ol style="background-color: orange;">
<li>Apply first coat of straight Alox, making a Z shape across the bullets, tumble, spread on wax paper and let dry overnight. This is a heavier coating than Lee recommends</li>
<li>Apply the second coat of straight Alox, just like step1</li>
<li>Apply a medium amount of Mica and shake around (see the tumble lube post)</li>
</ol>
This will result in a very heavy coating, however one single coating didn't work. It took 2 coats of liquid Aloxx and the Mica to resolve the problem. You will need to check the bullet seating and crimp dies every 100 handloads. Any buildup should be cleaned out using mineral spirits or another good cleaner. If you don't do this the buildup will eventually make a mess, and seat the bullets deeper. That can cause accuracy and potentially pressure problems. This is my preferred solution and what I use.<br />
<br />
Dillon has dies designed to pop out for cleaning, then be put back, all without messing up the adjustments. They aren't cheap, but they are very well made and make cleaning a no-brainer.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
<b>Extreme Alox 2:</b> Dipping the bullets into Alox also solved the leading problem. Alox applied using this technique is probably the most effective I've seen. That's the big plus, the negative is it's slow and takes patience. Rather than detail the how-to, here is a link with great instructions:<br />

<br />
<br />
If your revolver is super accurate with a tumble lube design, but has a leading issue, it may need to be lapped to the correct size. In my case, the leading was minimal and the size wasn't an issue. So Extreme Alox solved the problem and continues to leave a shiny barrel.<br />
<br />
That's a wrap for today. <br />
<br />
Have fun and shoot tight groups!Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2841706087367673439.post-70983031721459752732011-08-13T16:17:00.007-04:002011-08-21T13:15:58.288-04:00Part 3: Using The Ladder Test - 700X Result, Keith and Unique Final ResultFirst the mould & bullet used in this Ladder Test: The 358-429 mould from NOE is lapped and now it drops 178 grain bullets. I round it to 180 and use those recipes. Since the actual bullet weight is lighter, it's safe. Working the other way can cause unsafe pressures, so don't use recipes for a lighter bullet.<br />
<br />
A recap of Part 2 results: The 5.4 charge of Unique under the lapped TL-358-158 has proven to be extremely accurate. The leading problem reported in Part 2 has been completely solved. Look for an upcoming post "Extreme Alox" to see how. Ladder tests with a 357 revolver (a 6.5 inch Blackhawk in this case) is producing accurate loads. This continues to be a great surprise.<br />
<br />
Now for the 180 grain Keith. For a description of the test approach please refer to Part 1 and Part 2.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/KeithUniqueLadder.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://i878.photobucket.com/albums/ab341/prgallo/KeithUniqueLadder.jpg" width="396" /></a></div>
This time there are 2 sweet spots. The pairing of shots 1 & 2 is the first, then 3 & 4 is the second. That suggest 5.1 grains of Unique and also 5.7 grains of Unique.<br />
<br />
At this point, I know this bullet and the TL358-158 are the 2 most accurate moulds for a 357 magnum, and that the Ladder test produced a great load for the TL358. So I decided to shoot the 2 loads from this ladder off-hand, 25 yards with the open iron sights and unsupported in any way. I fully expect that off a rest they will group well, just like the TL358.<br />
<br />
First the 5.1 charge of Unique. This is looks to me like another great load:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/KeithUnique5-1offhand.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="307" src="http://i878.photobucket.com/albums/ab341/prgallo/KeithUnique5-1offhand.jpg" width="400" /></a></div>
<br />
The 5.7 load is just a bit bigger, but still very respectable:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/KeithUnique5-7offhand.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="335" src="http://i878.photobucket.com/albums/ab341/prgallo/KeithUnique5-7offhand.jpg" width="400" /></a></div>
<br />
Not bad!<br />
<br />
A review of the progress so far:<br />
<ol style="background-color: orange;">
<li>700X didn't produce a good ladder using the Blackhawk. Verfied later on, this combination isn't accurate. The 700X and the Taurus 66 357 is the most accurate combination, with that revolver. The variation of what works in one revolver vs another is quite large. So don't get frustrated is one of the "proven" recipes doesn't work in yours, try some other powders and you'll find one.</li>
<li>The TL358-158 ladder with Unique produced a charge of 5.4 (1 sweet spot). It checked out to be incredibly accurate. Producing a best group, rested and iron sights, of .668 inches. That's awesome.</li>
<li>The Keith ladder with Unique produced 2 charges (2 sweet spots). A charge of 5.1 and also a charge of 5.7. They are both excellent, with the 5.1 load having the slight edge. One off-hand test isn't conclusive in my book. But that is the result for this test.</li>
<li>With the leading of the TL358-158 resolved, it just edges out the Keith for accuracy, making it the preferred bullet for 357 magnums.</li>
</ol>
<br />
Coming up next, test results for H110 and the TL358-158. I plan to try all these loads out in the Rossi 20 inch M92 Lever action rifle. Oh, the Extreme Alox solution will be laid out in detail too. Without that, the single most accurate bullet would loose accuracy in 40 rounds. That would make it unusable.<br />
<br />
But it is resolved, the Blackhawk and the TL358-158 are now an awesome combination. If you have similar problems with a bullet leading right at the start of the lands (rifling) maybe Extreme Alox will solve your problem.<br />
<br />
At this point, the Ladder Test certainly work in a longer barrel 357. Give it a try to develop your most accurate loads.

A few key truths are made evident and discussed. I believe the results of this project translate to your 357 Magnum revolver and aren't only for my Ruger.<br />
<br />
For the time being, ladder testing and validation using H110 moved onto the back burner. 700X and Unique early results are covered.<br />
<br />
700X has proven to be one of the most accurate powders in the Taurus 66, and also the Rossi lever action rifle. The ladder test for the 358-158-SWC (tumble lube Lee mould, lapped and now dropping 168 grain bullets) going from 2.8 grains to 5.3 grains, in .3 grain increments:<br />

The 700X ladder test for the 358-429 Keith (lapped and dropping 180 grain bullets) ranged from 3.1 to 4.6 grains:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Keith700Xladder.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://i878.photobucket.com/albums/ab341/prgallo/Keith700Xladder.jpg" width="400" /></a></div>
<br />
The 358-168-SWC test results didn't look very conclusive to me, so I followed up with some accuracy testing to see what would those results would indicate. Wow, it wasn't pretty. Rather than posting picture of horrible groups, here is the bottom line:<br />
<ul style="background-color: orange;">
<li>The Blackhawk won't shoot this bullet accurately with 700X</li>
<li>This bullet causes light leading near the forcing cone, with all charges. It wasn't horrible, but enough to affect accuracy after 50-60 rounds. Not acceptable</li>
<li>The Blackhawk does not shoot either of the 2 best bullets well with 700X. Proof that bullet / powder combinations don't work equally well in every gun</li>
</ul>
So what does that say about ladder testing? Load accuracy is the result I was looking for and all that ladder testing promises to offer. The results weren't conclusive and when followed up with additional testing, 700X proved to not be accurate. As much as the other 357's love it, the Ruger doesn't.<br />
<br />
The Ladder Test can in fact save time in determining that the gun-bullet-powder combination isn't effective, there was no clear sweet spot because this combination doesn't work. I think that's a big plus.<br />
<br />
<ul>
<li>A note regarding the leading: It was a small amount of leading, right were the lands start. The area between the cylinder throats and the lands is critical in a revolver. <span style="background-color: white;">It's possible that the short 358-158 bullet allows gas to get around the bullet, in this critical area. Enough to cause this light leading, and the resulting loss in accuracy. Basically, a form of gas cutting. The leading occurred using Unique as well. With the longer Keith, there's no leading after 200 rounds. That's a big difference between the Taurus, that loves this bullet, and the Ruger.</span></li>
</ul>
<br />
How about the results from the Keith ladder test? This test indicated a charge of 4.1 to 4.2 to be a sweet spot. After testing, it wasn't. There was no leading with this bullet, but it confirmed that the Blackhawk just doesn't like 700X. At least with 2 of the most proven bullets in other 357's.<br />
<br />
Again, the ladder test proved to be helpful. It suggested a sweet spot that once tested, didn't work out. It saves time over testing 20 rounds, or more, at each charge weight (my old testing approach).<br />
<br />
Before I would have loaded and test 20 rounds at each of the 6 charges, for a total of 120 rounds. Using the ladder test, I loaded 6 rounds and could have validated it with 20 more, for a total of 26. I did load and shoot more than that to see if the ladder test missed a sweet spot, it didn't. So far the ladder test is looking promising, even in a revolver and even at 25 yards.<br />
<br />
But can it find a validate sweet spot? Here is the Unique ladder test with charges from 5.0 to 5.9. Not a huge range, but I wanted to give it a try.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/158UniqueLadder.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="376" src="http://i878.photobucket.com/albums/ab341/prgallo/158UniqueLadder.jpg" width="400" /></a></div>
<br />
Now we are talking! The sweet spot is clearly between loads 2 & 3. Here is a group using 5.4 grains:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/158SWCUnique5-4.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="270" src="http://i878.photobucket.com/albums/ab341/prgallo/158SWCUnique5-4.jpg" width="400" /> </a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
Please don't let my limited photographic skills mess up the effectiveness of these results. The ladder tests are on a big bullseye target. This test is on a target less than 1/2 the size. This group (excluding the shot I pulled) is a .668 group. Yeah, that's what I'm looking for! A sub 1 inch group, rested, at 25 yards using iron sights. That is a further indication that ladder testing (revolver, at 25 yards) WORKS.<br />
<br />
I was able further validate, this is one sweet accurate load. BUT! This bullet still has the leading problem. That tells me it's not the powder as much as the bullet and the Blackhawk not working together. Testing with the H110 will either be strike three, or may work. It remains to be seen.<br />
<br />
Conclusion: Early results of ladder test are positive. It saves reloading and range time by reducing the number of rounds needed to find a sweet spot. In my tests, the inconclusive results proved that there was not a sweet spot, another ladder result let me quickly determine that 700X didn't work with the Keith either. Then the third test produced a super accurate load, with a minimal number of rounds loaded and shot. That's very impressive.<br />
<br />
This is extremely useful since bullet moulds and powders don't always translate from revolver to revolver, or if you need to work up a new bullet & powder combination for your revolver. Both 700X and the 358-158 that work so well well in other revolvers barely even group in the Blackhawk. Unique in the Blackhawk is working out very well, even though it didn't give the best results in the Taurus. <br />
<ul>
<li><b style="background-color: orange;">A .668 inch group is the best I've ever shot with iron sights. That's exciting!</b></li>
</ul>
Part 3 is already in the works.<br />

Shoot tight groups and enjoy your 357 Magnum. The most versatile and fun caliber to cast and handload, in my opinion of course.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2841706087367673439.post-20614025238189387242011-07-24T13:52:00.005-04:002011-07-24T18:57:50.847-04:00Part 1: Using The Ladder Test - Incremental Load Development Method To Work Up Loads For A Ruger BlackhawkThis is part 1 of a multipart series. Over a period of weeks there will be follow-on posts with additional information.<br />
<br />
In the past I enjoyed shooting the Taurus 66, putting thousands of cast hand-loaded rounds through it. Now I'm working out the same loads with a Ruger Blackhawk, 357 Magnum. It's an older three-screw, 6 1/2 inch barreled gem of a revolver. The plan is to rehash the best loads and see what works best in this new-to-me revolver.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Blackhawk2-1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="266" src="http://i878.photobucket.com/albums/ab341/prgallo/Blackhawk2-1.jpg" width="400" /></a></div>
<br />
<br />
We know the most accurate bullet designs, and have proven loads to work with. However I've decided to use a Ladder Test. This is a great way to quickly validate the best loads, and to also work out some new powder-bullet combination's. See the "Most Accurate Bullet Moulds and Loads Table" at the top of the right-hand column for a complete listing. <br />
<br />
I'll start with the Lee TL358-158-SWC that has already been lapped. It drops full sized bullets with a .3604 diameter, that weigh 166 grains (I'll refer to them as 168's). They will be sized to .360 using a custom Lee push through sizer and lubed with Johnson's Paste Wax and Alox.<br />
<br />
The plan is to use three powders. Two of them have demonstrated incredible accuracy.<br />
<ol style="background-color: orange;">
<li>700X being a fast burn-rate powder</li>
<li>H110 being the most accurate magnum powder tested to date, and I don't have a magnum load for this bullet, yet </li>
<li>The last is Unique, it's a great powder that gets loaded more than any others, by more handloaders across the county than any others. It's generally accepted to be be the most flexible handgun powder since it's inception many years ago.</li>
</ol>
<br />
Now that the stage is set, what the heck is the<a href="https://docs.google.com/uc?id=0B74xSLouy2aUMjAzNzE4YjgtNTZlZC00NWVlLWE0YzMtMmM2YjlhZjdhMTMy&export=download&hl=en_US"> Ladder Test - Incremental Load Development Method</a>. For a great read, click on that link. It will download a PDF article written by Randolph Constantine. It is a great explanation of this test approach, originally devised by Creighton Audette in the 1950's. It will frame the method using long range distances and rifles. The concept and approach is important for our purposes as I apply the Ladder Test to a iron sighted Blackhawk, indoors, at 25 yards.<br />
<br />
<br />
<u><b>Let's Get Started</b></u><br />
<br />
Now the you have the concept behind the a ladder test, there are a couple of tools that make it much easier to handload one cartridge each of several different charges. Using a powder measure is possible but time-consuming and a just not-much-fun.<br />
<br />
Borrow or purchase a powder trickler. They are easy and quick to use. The Lyman below is what I use, but all the major brands have good ones available (this cost $20 at Bass Pro Shops):<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Trickler-1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="218" src="http://i878.photobucket.com/albums/ab341/prgallo/Trickler-1.jpg" width="320" /></a></div>
<br />
Use the trickler to feed the powder directly onto your scale. You can feed it quickly, or as slow as 1 speck of powder at a time. Great for weighing lot's of different loads.<br />
<br />
<br />
Next is a funnel, to get that weighed charge into a sized, primed and flared 357 magnum case.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/Funnel.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://i878.photobucket.com/albums/ab341/prgallo/Funnel.jpg" width="297" /></a></div>
<br />
That's all it takes, assuming you have the scale and other reloading gear already.<br />
<br />
The Ladder that I worked up and loaded for this test is:<br />
<br />
<ol>
<li style="background-color: orange;">TL358-158-SWC that is lapped and drops 168 grain bullets</li>
<li style="background-color: orange;">H110, this is really an attempt to work up a great load with combination because I don't have one for this bullet</li>
<li style="background-color: orange;">Charges in the ladder:</li>
<ol style="background-color: orange;">
<li>11.6 grains of H110</li>
<li>11.9</li>
<li>12.2</li>
<li>12.5</li>
<li>12.8</li>
<li>13.1</li>
<li>13.4</li>
<li>13.7</li>
<li>14.0</li>
</ol>
</ol>
<br />
I used a few extra rounds to warm and foul the barrel. This target is the result; 25 yards from a rest and iron sights:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i878.photobucket.com/albums/ab341/prgallo/H110-168-Ladder-1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="280" src="http://i878.photobucket.com/albums/ab341/prgallo/H110-168-Ladder-1.jpg" width="400" /> </a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Revolvers (handguns in general) don't always walk up the ladder. Sometimes a heavier charge will shoot lower. In this case, that happened. Recalling the article on how to do this testing, look for 2 or more holes close together, with sequential numbers only. There's one set that shows the sweet spot, numbers 7 and 8. That puts a nice sweet spot at 13.5-6 grains, that should provide good groups.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I have an advantage at this point in working up the load. From prior test results (thousands of rounds) I know the diameter, OAL and that this bullet design has the capability to shoot sub-1-inch groups at 25 yards. That should decrease the time spent refining the load for maximum accuracy.</div>

Or rifle. And you can't buy them but once a year, usually.<br />
<br />
NOE is a small mould manufacturer and only does "runs" of moulds. It seems like they have some of these in stock. You will have to go to http://castboolits.gunloads.com/showthread.php?t=91999 and sign-up and let NOE (Swede Nelson) know you want one by posting and PMing.<br />
<br />
I'm a very satisfied customer of NOE and promised to tell you how to get accuracy from your 357. This mould is 1 of the top 2 for accuracy. For a full-house magnum load, this is the best mould and bullet design. It does well downloaded too, but does it's best with a load of H110.<br />

One of the 2 best in a 357 Magnum Revolver & the 357 Magnum Carbine.<br />
<br />
The lapped mould is dropping 166-167 grain full size bullets. Sized from .3604 to .360 with a custom Lee sizer, and lubed with 3/1 JPW/LLA (Lee Liquid Alox) or pure JPW (Johnson's Paste Wax) (the best lubes for this type of load). Loaded over 3.5 grains of 700X, and a long OAL of 1.610. They are shooting great in the rifle, and the revolver. These light loads, are low recoil. Yet in the revolver they can knock down a 100yard Ram at IHMSA Silhouette events. <br />
<br />
To give you an idea of this from the Rossi at 25 yards, off-a-rest, 5 shot group, here is the dime-on picture:<br />

<br />
That was a fun day at the range! The approach to casting and handloading in the other posts produce this kind of a result. Hopefully the test results, forced ranking approach to accuracy, and the information in general helps your groups.<br />
<br />
More about shooting the 357 Magnum Revolver with iron-sights, standing & off-hand. That is standing, with 2 hands and no supports. Once you have the most accurate load, this is one of the fun ways to enjoy yourself. I love red dots and scopes, but iron sights are simple and, like I said, FUN!Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2841706087367673439.post-55797787415610085702011-06-29T21:07:00.007-04:002011-09-29T10:24:56.577-04:00Update: The Best Way to Tumble Lube the Best Cast Bullets<br />
Lube testing with 357 magnums has produced some fascinating results. This is an update on the prior lube posts. <br />
<br />
For target loads with fast powder: The top 2 tumble lube variations of lube are
JPW/Xlox mixed 3/1 and also pure JPW. They are so close in performance
and accuracy that they are really equivalent. The JPW/Xlox (or LLA, it
doesn't matter) gets the very slight nod because the best grouping I've
ever shot used it. Also, after shooting many groups and taking all the
measurements, the results are, on average, within .1 inch of each
other. That's from 25 yards off a rest. This shooter isn't good enough
to call that conclusive.<br />
<br />
This is with the Lee TL358-158-SWC,
lapped to drop 166-7 grain bullets. The most accurate design for a light-fast-powder load in a 357 magnum. (another test result is coming...)<br />
<br />
Added later: I'm using up the Xlox/Alox that I have, using it to stretch my JPW. Once it's gone, I'll be using pure JPW again. I just hate to waste anything. <br />
<br />
<ul>
<li><span style="background-color: orange;">Note: Tumble
lubing standard groove bullets, for the light loads, may work well.
However I haven't spent much time testing this combination. There is
no leading, but accuracy may drop off. It would be slight, less than
1/4 inch at 25 yards. But that's speculation, since I haven't found a
better more accurate bullet. I don't plan to test this more. Shooting
less accurate bullet designs is not high on the list of ways to spend my
time</span>.</li>
</ul>
<br />
Heavy
magnum loads using slow powder are most accurate with a heavy bullet.
Using a 358-429 lapped mould, that drops 178 grain bullets has proven
to be the most accurate. Using Darr lube has produced the best results
with this combination. Other conventional lubes may work too, there are
too many to test them all.<br />
<br />
<span style="background-color: orange;">NOTE:
Tumble lube on a large-groove bullet, with a magnum load, is proven to
loose accuracy. This is not speculation. Up to 1/2 inch at 25 yards.
Not that the TL fails to lube as there is no leading. I suspect the
huge empty lube groove doesn't support the bullet base adequately.
Causing the accuracy to drop off. That is with very soft bullets, so
it may not apply to shooting WW or harder. Since the harder bullets
have also proven to be less accurate, I won't spend time doing
additional tests with them either.</span><br />
<br />
Some general comments: That
doesn't mean tumble lubing a with a small
conventional-lube-groove will be less accurate. But it might, at longer
distance. If you measure 25 yard groups with a caliper, and care about
fractions of an inch in group size, it's worth testing.<br />
<br />
If you shoot at 15 yards and do an eyeball, "looks good to me", you probably can't tell the difference so it doesn't matter.<br />
<br />
The
results in your gun, based upon lube groove design, lube, alloy, and
charge should be similar to mine. Or said another way, a huge lube groove (like a Keith)
with a soft bullet and TL may not be the most accurate combination,
depending on the charge. So try it out, at some distance. When a
tumble lube design proves to be extremely accurate, try some JPW/Xlox
3/1, or pure JPW. <br />
<br />
I hope this is useful information that helps you shoot tighter groups with your 357 Magnum.Unknownnoreply@blogger.com1
