[QUOTE="Pdvdh, post: 403200, member: 4191"] The rifle chamber may have excessive headspace, from the bolt face to the shoulder. If you back off the resizing die to the point you're barely setting back the shoulder of the case, then you should experience good case life. Make sure the barrel threads are still tight in the actioin, and haven't loosened up. An excessive headspace condition is about the only thing that will cause premature case-head separation, in my experience. Even if the bolt to belt headspace is a bit excessive, if you headspace off the case shoulder instead of the belt, I think your problem will likely be solved. [/QUOTE]
