I have always used the 140 Nosler partition. It fit the A dial on the old Redfield Accutrac scopes real well. The built in range finder worked real well too. A 140 partition will punch through both shoulders of a 150 buck at 600 yds. You can't beat a 7 mags if you consider how much power vs recoil. In my opinion
