[QUOTE="davewilson, post: 180441, member: 4491"] i understand what you're saying about the size of the hole and always felt that way until this summer when my gun started to not go off once in a while. also during this time the primers were not only heavily cratered, but some were completely pierced. this seemed strange since my loads were very conservative. all of this went away with a firing pin spring change.i don't know what the weak spring measured, but it was close to 20. the new one measured around 28. as you say either doesn't compare to the pressure on the other side but seemed to make quite a difference.
