[QUOTE="Mikecr, post: 840407, member: 1521"] This is probably true with your the 20deg shoulders and high body taper of a 243/308, and possibly excess striking forces. It would be even more likely with a 270/30-06, both a solid standard in poor case design. It doesn't happen with better designed cases with 30deg shoulders or more. In fact, it doesn't even happen with smaller cases like a 223, even with a low shoulder angle of 23deg, because the shoulder is short. Yes, anyone here can test this quick, and form their reasoning. This is actually true, without qualification, and happens with all cases on firing. [/QUOTE]
