Been having problems with misfires in my 2 625s with 45 auto rim R-P brass. Primers seated correctly CCI large pistol,was getting 2 - 3 ftf out of 6 rounds.
I was having this problem with one pistol so I brought my other 625 same thing. After some poking around found out that the primer pockets could be shallow. So I deprived some of cases measured pocket depth .117-.118".
So bought a primer pocket uniformed and corrected the problem.
I've some ammo loaded in Starline brass that I'll try later.
