I have been working on a 9mm semiwadcutter load. Today I got back to it. I put 5.6 grains of BE-86 in Starline brass, and I used 125-grain Missouri Bullet semiwadcutters. I'm using Winchester small pistol primers.
I am now happy with my average velocity (1134), but several of the cases I shot today now have bent mouths.
I read that the recoil spring and magazine springs can cause this. My magazine spring seems fine, and I compared the recoil spring to one from another Glock 26. I don't see any problems.
Should I be concerned about this? If not, I am planning to use this recipe to polish off this box of bullets.
The cases seem fine otherwise. It's hard for me to see how a hot recipe could cause this.
