[QUOTE="MagnumManiac, post: 2415112, member: 10755"] The only way to be certain is to rip the barrel off and take measurements. It sounds to me that the chamber is oversized at the rear, it may even be eccentric. You could do a chamber cast and measure off that. Can you take some pics of fired brass and post them please, it will make it easier to determine the issue. You may want to adjust your die so that the headspace measurements stays the same as a fired case. The body will be sized regardless and may not prevent further head separations unfortunately. Cheers. [/QUOTE]
