I tried those Nosler Accubonds in my 338 win. mag, tried working up different loads with different powders, never could get them to shoot to my satisfaction. I was useing 225gr. Accubonds in a Rem. 700 BDL. I havnt tried any in any of my other guns, but I know my 338 dont like them. The best bullet accuracy I get from it is with Sierra, Hornady and Speer Grand Slams. I was getting about 2" groups at 100 yards with the Accubonds, which doesnt cut it with me, I can shoot Sierra GameKings, Hornady Interlock SST, or Speer Grand Slams in the gun and consistently shoot under 1" groups all day. All guns are different, some guns will shoot certain bullets better than other guns will.
