I have a 9mm beretta and also a taurus, both barrels slug to .357 my cast bullets come from the mold .001 larger than this at .358 and squeeze through my dies a bit when crimping. we all know that exessively large bullets will cause the chamber to pinch the case and cause unacceptable pressure, is there a way to know that this might be happening when you chamber the round before you shoot it? ive noticed that even factory 9mm at .355 diameter sticks out of the chamber a bit until the slide knocks it in just as my cast bullets do. is there anyone with experience in this?
