Couldn't agree more, I've never been one to embrace the magnum craze. There is a constant push towards more and more "performance" or "terminal effectiveness" in hunting. It gets out of hand fast. I have no doubt either of the cartridges the OP mentioned would do the job on deer sized game. My comments were more directed in the fact that I think the trajectory, projectiles available to the round and in the end performance bears out to the decision I would make. A .223 with a good bonded bullet in the 64-75gr weight would do fine on deer as well, if legal in the state (albeit that many on this board would find that prospect appalling).
