[QUOTE="Broz, post: 836075, member: 7503"] Seat the SMK at -.060" and back off to 90 gr of H-1000 and work up. Or work back toward the lands and see if velocity comes up staying at 90 gr. Also watch what accuracy does at 200 yards. 92 gr with a 300 gr bullet is a stout load in summer temps and the 2800 fps is right on par. Usually with RP brass and a 300 gr loaded with 92 to 92.5 gr of H-1000 the brass lasted me 3 firings and showed slight ejector pin marks, a slight bolt lift but not much smear of brass. Even with Bertram brass and 92.5 gr with a 300 Berger I get a shadow of an ejector pin and 2835 fps. You will probably be able to run the Bergers with a little more charge and get a little more speed due to the shorter Bearing surface. Jeff [/QUOTE]
