I would enjoy some input on what bullet I should reload for my .300 Winchester Magnum. I will be using it for elk hunting where shots could range from 50 to 350 yards. The gun seems to be rather picky. I have tried Partitions, A-frames, and Barnes X`s but none of them will group under 2.5 inches. The rifle seems to love 200 grain Sierra Game Kings, 180 Grain Hornady SST`s and Interlocks, and 180 grain Ballistic Tips, and 180 grain Speer Hot Cores.
I guess I would like to shoot the 200-grain Sierras, but worry they are not tough enough to hammer through a quartering elk.
Any thoughts or ideas would be appreciated.
