I killed a nice little 5x5 a few years ago with a 150gr Silvertip fired from my M1A. One shot, perfectly broadside at about 70 yards. Dropped the bull in his tracks. While that is what I used at the time I wouldn't recommend the round for elk. The round didn't exit but turned his lungs into spaghetti. Like many have said before me, shot placement is everything. On my typical elk rifles 300wsm/30-06 I typically use either coppers or bonded rounds of 180 grains. Coincidently, this was the only bull that I have shot that literally dropped in his tracks with one shot. I would have dreaded having to try to track that guy had the shot been anything but perfect.
