Any differences in capability between the rounds in modern actions is basically a rounding error and a way for gun scribes to burn ink. Either one is a near perfect rifle for deer sized game, and OK for elk with the right bullet, without kicking the snot out of you in a light rifle. What more can you ask?
I've loved all my 7x57s, and particularly like the commercial Mauser I have now. For some reason, I've never bonded that way with my 7-08, which is a M700. Its accurate, its killed everything its been shot at cleanly, but I really only keep it around as a loaner and spare. Go figure.
