I have a Mauser 1914 .32acp. The bore measures .309".
I replaced all the springs and it shoots factory ammo just fine. I saved the brass and got some bullets from Montana Bullet Works (.311" 75 grs).
I loaded some dummy rounds. The published data I've found shows the OAL to be approx. .984". I cannot get the rounds to chamber until the OAL gets down around .925". Fired and sized or unsized cases drop right into the camber (barrel removed), so I know it's not the brass.
I'm kinda concerned about the pressure from having the bullet seated that deep. Could it be a problem? (1.5 grs Bullseye).
I just ordered a Lee bullet sizing die in .309".
