260 ain't gonna touch the 264WM's ballistics...a 140gr bullet at 3100fps+ has serious long range oomph.

Can't help but think moving the same bullet 300fps+ faster than a 260, with 20+ grains more powder behind it, is going to result in one heck of a barrel burner. Probably not a problem if the primary use is hunting...

For the purposes of hunting whitetail and smaller game, a 260 carries plenty of energy to ranges beyond what the average hunter should probably be taking shots on deer-sized game.
