I have shot many whitetails with those bullets without issue, I found that 270, 30-06 and 7mm mag all produced greater tissue damage and meat loss. You might want to slow them down a little more and see. Unless you are a factory rep or something or a professional hunter, you never get to shoot enough game to really learn how bullets perform. Decades ago my friend and I would buy goats, injured or sick animals at the local auction, etc very cheap and shoot them and then do autopsies on the carcass to see how the bullets performed, then use the remains for coyote bait. Probably would not go over so well today.
