[QUOTE="Shadowrider, post: 3363591, member: 3099"] Crimp isn't what holds the bullet in place. Tension from the case walls is what does that. If you are crimping the case into the bullet enough to deform it you are ruining accuracy and it still won't stay put. Shoot a revolver much and you'll see that there is no amount of crimp that will hold a 230 grain .45 bullet in place unless it has a cannelure to crimp into and that doesn't work with autos that headspace on the mouth. Those that crimp that hard are probably headspacing off the extractor and don't even know it. In 9mm I used to play "name that case" just by the feel on the handle when seating a bullet. CCI Blazer is really thin, I used to could tell those every time. Couple of others that escape me are just as bad and some brass is too actually thick for plated bullets. TZZ in .45 comes to mind, it's thick stuff as are some .mil stamps. I've had plated bullets peel when there was plenty of bell on them. Increasing it would actually make the seating die squeeze back down on the bullet as you were sizing them and if you pulled it out and looked before crimping you could still see peeling with the bell still there. Maybe they're better now but I bought a large amount of 9mm, .40 and .45 X-Tremes in a group buy once. I swore off of them and all other plated because they are so finicky to load and it's a crapshoot as to whether your gun will "like" them and shoot groups or just shoot shotgun patterns. I'd rather shoot lead and clean up the mess afterward. These days it's coated hardcast or jacketed for me. [/QUOTE]
