G-tar-man Posted January 14, 2014 Share Posted January 14, 2014 (edited) I've been having trouble figuring out why my case necks are bulging recently. I haven't changed anything besides bullet and powder charges. The dies are setup the same, other than changing the OAL for the bullet seater. Do I have too much lube on the cases possibly? It only bulges when seating the bullet. Edited January 14, 2014 by G-tar-man Link to comment Share on other sites More sharing options...
HighCountryStalker Posted January 14, 2014 Share Posted January 14, 2014 (edited) My guess, having done the exact same thing. I bet you are using a combination seating/crimp die. When adjusting the OAL you screwed the die in further which increased the crimp at the same time and the seating then collapses the neck. Since there really is no need for crimp at all, back the die off, screw the seating plug in most of the way and then adjust the die back down until achieving the OAL you want.

Doc Hunter Posted January 14, 2014 Share Posted January 14, 2014 If the bullet does not have a crimp groove - don't crimp it. Link to comment Share on other sites More sharing options...
Alaskapopo Posted January 15, 2014 Share Posted January 15, 2014 If the bullet does not have a crimp groove - don't crimp it. Hell I don't crimp FMJ's with a crimp grove anymore. No need for it. Pat Link to comment Share on other sites More sharing options...
Doc Hunter Posted January 15, 2014 Share Posted January 15, 2014 Popo, I would agree. Crimps destroy many a good bullet before it even has a chance. Link to comment Share on other sites More sharing options...

Pat I agree with Doc. I have pulled bullets picked up at the range and you would be amazed at what you find pulling reloaded pistol AND rifle bullets. Military bullets are crimped because it's the military. Rifle bullets need to be crimped only to keep them from moving under recoil. That's why most .224 bullets don't have a cannelure and it is a mystery to me why people want to crimp rifle AND pistol bullets WITHOUT a cannelure.

Barrel tolerance is tight and no crimp caused the round not to chamber. Now as far as rifle does no crimp also go for ar platform or just bolt action as far as moving under recoil.

Sent from my iPad using Tapatalk HD I don't crimp AR bullets of any type and have never experienced bullets being pushed back into the case. I've never had to 'crimp' a 380. Maybe my Sig 230 chamber is larger. I have an RCBS taper crimp die set to put the bullet back to factory demensions. Link to comment Share on other sites More sharing options...
