[QUOTE="Westfork, post: 1635593, member: 109839"] Having the same issue with a Mossberg MVP in 5.56mm. Primer edges are round but they crator. Worse yet, I can't even get close to Book Max with H335 or CFE223 and Sierra 65 grain Gamekings. The primer pierces and blows back into the bolt preventing any further firing. No other signs of high pressure, extraction is smooth. [/QUOTE]
