[QUOTE="Mike Matteson, post: 1847082, member: 101791"] No weight on the bullet being used. I would say that your are a little over pressure. Need to back down a little. Those primers are showing high pressure signs. The bolt doesn't need to be hard to open to be over pressure. When it's hard to open it's really over pressure. Diameter of the firing pin hole to the firing pin doesn't mean that much. It the pressure that pushing the primer back around the firing pin into the opening. Generally every rifle is different in handling pressure. A different bullet from different manufactures cause higher of lower pressures even with the same bullet grain weight. I haven't used all copper bullet in 18 or so years. At that time I tried Barnes copper bullets I couldn't get the groups nor velocity from the Barnes bullet as to a noslers in the same grains. At the same time I wasn't trying to shoot 1000 yards either. SSS [/QUOTE]
