My first foray into loading the 300 WM was with 180 Hornady BTSP Interlocks and a real STIFF charge of IMR4350, which turned up good velocity (3100 +) and great accuracy -- just under 3/4" groups. The bullet came apart pretty explosively on a large 10 point buck, so I re-thunk the whole thing, and settled on a 168 Barnes TSX, and a moderate load of RL-22. All the accuracy, and most of the velocity. Killing machine that rifle - well out to about 300 yards anyway.
