[QUOTE="David Emerson, post: 1845473, member: 112579"] Primers can be deceiving. I have seen a weak striker spring cause this. The ejector mark is a sure sign of high pressure. I measure a new case and when you have .0005 gain in diameter you are close to maximum. Measure just forward of the extraction groove on the solid portion of the head. With normal strength brass it takes 70,000 psi or close to make an ejector mark. [/QUOTE]
