[QUOTE="bigedp51, post: 1705032, member: 28965"] And these Fed GMM primers he is using do not have a cup thickness of .025. I would first try a thicker cup primer and if that does not work then have the bolt face bushed. If you Google the problem when switching to small rifle primer brass that pierced primers are a common issue with the thinner primer cups. Again my advice is to switch to any of the primers below with a cup thickness of .025 first and see if the problem stops. [IMG]https://www.longrangehunting.com/attachments/primer-dimensions_zpsl8c4fymz-jpg.147818/[/IMG] Below are small rifle primer cases and the thickest primers are .025 and large rifle primers are .027 in cup thickness. And the thinner cups can cause more problems than the thicker .025 primers.
