The inconsistency of AAC blowing primers, even within the same batch and with similar COAW has me pondering that the AAC bullets are being loaded at the very absolute edge of a chamber spec. IME 223wylde chambers are having much fewer popped primers than the 5.56 chambers lends credence to it being something with it the cartridge at the throat causing a pressure spike in some barrels. Would explain the inconsistency between "My whole mag popped" vs the "Ive had one in a thousand" you get with the AAC 77s
