[QUOTE="D.Camilleri, post: 1323697, member: 2567"] I finally got a chance to go to the range this morning for a few practices shots. My first shots were with some of the RP cases that got accidentally bumped .010 too far back. Accuracy very good, velocity 2886 with 99 grains of RL33 and 300 gr Berger OTM, OAL 3.800 +-.002 This load turned out to be a little on the hot side, probably due to the shoulder being set back and reducing case capacity. Next up were some new Bertram brass, OAL 3.800, 99 grains of RL33, 300 GR Berger OTM, ambient temp around 65 degrees F, Velocity 2815-2820 pressure seemed acceptable, no hard bolt lift, no noticeable ejector marks. Last up Bertram Brass, 99 GRs RL33, 300 gr Nosler Accubond, 3.720 OAL, .020 off the lands, 2810 velocity, same vertical point of impact, about 1/2 inch right. All of these loads shot sub .5 moa. So far the only draw back to the bumped shoulders is a rise in pressure. I might try dropping 1 grain of powder in these and try them again. [/QUOTE]
