I've been loading 9mm for a while and am working out some issues with Fail-to-Feed thanks to the great advice I'm getting here. I'm also using a Lee set to load 45ACP. When I load 9mm the round goes in and comes out of the Factory Crimp Die with minimal effort. When I load 45ACP though, the round has a very significant bump going into and coming out of the Factory Crimp Die. I don't have any problem with the rounds at all they chamber fine and no problems at the range so far. I'm just wondering if this is a common experience with 45ACP loaded with Lee dies. Bullet diameter is about 0.448 and using Federal brass.
