The only problem you will have from undercrimping 45 acp is function. The bell on the case will keep the gun from cycling. That is IT!

Overcrimping is anything more than just putting the case mouth back in contact with the bullet. Depending on how much you overcrimp the problems can be pretty varied. Bullet setback and poor accuracy are very common problems with an excessive crimp.
