I used the 170gr RN Pro Hunter in a 7x57 for years on whitetails very successfully. Then I had one blow up on a Black Bear's shoulder on a Maine bear hunt. We lost the bear.
I haven't used one since. I can't comment on the Game Kings, but I would restrict use of Pro Hunters to deer and the like. I will say that the Pro Hunters were very accurate in my rifle.
