the rifle is a 300WSM and the type of game is whitetail deer and black bears. i prefer to shoot 165 0r 168 grain bullets. alot of people say that the nosler partition is a great bullet. but my concern is that a bullet like that coming out of a high velocity magnum rifle wouldnt expand properly in deer sized game. so i guess my question is who makes the best 165-168gr bullet for deer sized game?
