[QUOTE="tobnpr, post: 2256811, member: 68758"] The cratering could indicate an oversize FP hole- even with normal pressures. High pressures obviously would exacerbate that and I suspect you can get primer "flow" into typical clearances with enough pressure. Headspace looks to be long by spec- which is 1.541 for min, 1.551 max. Your fired brass at 1.563 would be twelve over SAAMI max. How did the case diameter (above the casehead) compare to the new brass? Absent any evidence of swelling there (thinner case wall if exposed due to shallow chamber) I wouldn't see this as the problem either. If you weren't having hard primary extraction I'm thinking "other than" excessive pressure. [/QUOTE]
