I have also used the game king for years in my 30-06 (150 gr) and .270 (130). I have taken many deer with them. They are accurate and the deer die when hit. I went with game kings simply because I picked up a half box at a tag sale and found that my rifle liked them. They work for me but this is not to say another bullet would not work as well. I suspect that all modern hunting bullets work pretty well. Just choose the one that your rifle likes and you are ready to go. Don't agonize over the decision.
