I’m loading my 357 rounds up to 38 Special +P+ levels with 7 grains of Unique pushing 158 grain Berry’s bullets. I’m getting consistent keyholing with these rounds.
I’m shooting these from my S&W 357 Carry Comp with a 3” barrel that’s ported on top about a 1/2” from the muzzle.
Any ideas on the cause?
