I've promised some more test results, and plan to continue updating this blog. 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.
The local shooting range that closed in February is still being refurbished in late May, that's another twist to getting shooting time.
However, I'm still testing, casting, shooting and measuring results and will continue to publish it all right here.
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.
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.
Have fun shooting tight groups with your 357 magnum!
