[QUOTE="emp1953, post: 2414362, member: 71817"] The fine raised ring around the firing pin strike is called cratering and is a sign of high pressure. The metal of the primer cup is flowing into the firing pin hole in the bolt. Back off a bit on the powder charge. Try it -1gr and fire a few, then -1/2 gr at a time until the cratering stops. While the 700 action is strong there is no need to tax it every time you pull the trigger. After you hit that load, you'll most likely have to fiddle a bit to hit another accuracy node. Also these magnums are known to erode the throat faster than non magnum calibers. Backing off the load a bit may get more life out of your barrel. You might try a couple of the same loads but without the magnum primers. [/QUOTE]
