Well, maybe I'll go for a .300WM, it might extend my effective range on out to 600 and 700 yards. I currently limit my 06 to 500 yards because of bullet performance. With higher velocity the same bullets would perform better at longer ranges.
As for recoil, could not be any more than my TCR with the .338WM barrel, or the Encore with the .416 Rigby barrel.
