I would highly suggest the Barnes 180gr TSX (triple shock). I've shot 2 moose with my 300 wby @ about 150 yds, one through both shoulders, and the other a texas heart shot, both dropped right where they stood. Broadside shot went through both shoulder blades and exited the far side. The other entered the left hind quarter and exited the opposite front side. That's all I'll ever shoot at big game. Very accurate too!! good luck!!!!
