In my experience the .257 is a LONG way from minimal on deer-sized game. In fact quite a few people here in Montana use it on elk with complete confidence--or the .25-06, which really isn't as different as many people imagine.
Both Eileen and I hae used .25's from the .250 Savage to the .257 Weatherby on a bunch of game. They all kill real well if the bullet goes in the right place.
