[QUOTE="Dave in WI, post: 1634921, member: 102495"] Built a 223 Rem on new 700 action. I'm getting cratering on all loads fired, even factory. A few of my [B]handloads[/B] even pierced primers. I'll try to list as many things as possible to eliminate questions or things to check. Rifle is 700 build on new action. I trued action using Manson receiver accurizing kit. Bolt face and lugs squared. Closes on GO and does not close on NOGO. Barrel is 20" Green Mountain full profile 1-8 twist. Firing pin diameter: .075" Firing pin hole: .078" Firing pin protrusion: .052" Handload is once fired Starline brass that was first fired in this rifle. I did not bump shoulder when resizing. Overall the rifle fires great and have not seen any signs of over pressure in load workup. Other than primer cratering even on lower loads. I have also included a taget fired at 100yd while doing bullet seating testing. I also tried swapping out the firing pin assy from another used 700 to see if possible weak firing spring spring. Thoughts?
