Bart, thanks. I had a brain freeze though on the twist rate, it is actually a 1:12 twist, not a 1/10.
Are there advantages to IMR4064 over other powders like Varget and Reloader 15? My Lyman book lists load data for IMR4064, but I'm a little confused--it says 41 grains under a 190gr bullet is a compressed load, but that 43 grains under a 200gr bullet is not.
Is a Wolf primer just as good as any other?
