Thread: bolt failure P14

@mucko. Fair enough. Just one thought. Seems more likely to me that case failed by head separation before the bolt. When you mentioned loose primer pockets I thought to myself that cases may be on the way out. Suggest you see if you have any cases left. Take into a dark room and look into them using a tiny light.Look for a dark groove up little from the web. I had one give way on extraction a few years ago. When I checked others I found several more. Resizing off the shoulder instead of off the belt is the only way to control this. The long chamber in that rifle was stretching brand new Norma brass about 12thou at shoulder, which transferred brass from above the web. Incipient Case head separation is sometimes hard to detect especially in belted magnums but I understand can in wordt case scenario create the situation like yours.
