I have the Savage LRPV in 6 mm Norma BR with a 12" twist. I am getting good groups at 100 to 200yds. I am looking at the Savage Benchrest Rifle in 6 mm Norma BR, it only comes in the 8" twist. I will be using it at the same distance's. What bullets would stabilize at that distance? Any feedback on this rifle would be appreciated. Thanks in advance. DRPLP
