New PM45 rounds get stuck

[DJK11]

Great advice especially #1. Bullet setback is real, I’ve experienced extreme setback with my p380 and Speer GDHP. Not much crimp used with the GD and a very steep ramp on the 380 is a recipe for setback. I’ve measured more than .020 setback loading a fresh round.

Forgot to mention, if an ejected round gets hung up and is pinched between the breech and slide or chamber, setback could happen. Kind of vice like action squeezing the round shorter.
