The 150 GameKing in a 270 will get through about any deer out there. It is a fairly stout bullet. That is all a buddy of mine shot in a 7400 he had when he hunted in the woods. He killed a lot of deer with that gun and said it was DRT on timber whitetails with complete penetration.
Was a Barnes or Partition fan for most everything else but he said that combo of 270 and 150 GameKing was as good as he could ask for.
