Been a 357 afternoon.
100 rounds of 158 grain jsp with 7.9 unique
Then......for a test batch made up 50 rounds with 14 grains imr4227 using the 158 grain jsp. Lyman 50 says imr4227 with that bullet is 12.2 to 16.1 so I went for the middle of that range. If imr4227 works well I'll bump up the charge and I'll be excited because 4227 meters like a dream. For the test batch I weighed every charge and 49 throws were 14 on the nose and one was 13.9. If I decide to make a bunch of these it'll be quick work.
