Anyone ever thought about building a 450 Bushmaster heavy b.r. rifle. I dont shoot anymore except 1000 yard on occasion, but am thinking about building a 450 for 100 and 200 yd. I have an AR light barrel 450 B.M. that will shoot 1/2 " 5 shot groups at 100 with a 6 power scope. The cartridge has potential. .45 would be a wide hole in the target shooting for score. I know that it wouldnt be in the small group game. The 6mm owns that. I think the Bushmaster would be legitimate in a full benchrest rifle.
