Go with a predator SA and run a 260, or 6.5 creedmoor or a tac 30 and run a 6.5x47 since it doesn't need the extra length of the wyatts.

My SA mag face predator from last years group buy is finally at the smith's having a brux #4 interupted fluted 10 twist 300 wsm barrel put on. I almost got a stiller for my 6.5x47 but I had a SS rem SA handy and the smith is trueing it up for a very reasonable price. Same smith is doing both of them now and I'm hoping to have them soon.
