[QUOTE="IridiumRed, post: 3002592, member: 24315"] #34s are supposed to have a harder cup / take a harder hit from firing pin to set off. Designed for military semi autos like M1 Garands, M14s, AR10s, etc. Those have floating firing pins, the firing pin just sits in the bolt, when the bolt goes forward fast to load new round, FP goes forward too until it bounces off primer, usually leaving minor indent. Thats the reason why you should load from the mag on those rifles, not simply put one in chamber and let the bolt fly... bolt gets enough extra speed the firing pin -might- have enough xtra power to actually set off the round by itself, wo help from the hammer... a slamfire... very bad bc bolt may not be fully locked up, or at minimum the rifle is going off unexpectedly #34s being harder is supposed to help prevent that (slamfires). Theyre the LR version. #41s are small rifle version for .223/5.56/AR15s etc [/QUOTE]
