Well, a .25-264 Win Mag would be very similar (capacity wise) to the .257 Wby. But the 6.5-300 Wby is a full-length magnum and has measurably more capacity than the .264 Win. Not really apples-to-apples.Translation: We have a .257 Wby so we don't need a .25/.264 WM even as a wildcat, but while we have a .264 WM we still need a 6.5 /.300 Wby. Why? Is the 6.5/.300 Wby THAT much superior to the .264 WM?
