Got a question on crimping. First of all I read that the .223 should be crimped, right? Next when I go to crimp the case or bullet whatever you prefer I screw the die in till it touches the neck, then give it a 1/4 turn more. Then the cam arm kinda pops when fully extended. I went a bit too far on first couple and the neck was pushed down into the shoulder just a bit not too much then loosened it up a bit till I thought it was good. The thing is though I can't see the roll crimp that its suppose to have. I can't tell a difference between the uncrimped and crimped. Should you be able to see the crimp? I can't tell. And the ones that have their shoulder pushed down can I use those or should I take apart and salvage what I can?
