The 7x57 lives on because sons have seen their Dad's success w/the round and their sons...you get the picture. Not just on deer but sheep,big Mule deer, elk, moose and all north American game. It's ability will never die. A round that kills all out of proportion to it's size. It's never just enough but like more than adequate. My Dad's favorite, my favorite, and if my son gave a darn about hunting it would definitely be one that I would endorse to him. 7x57, 257, and 250-3000...three rounds that will never die. powdr
