Another factor is how many rounds are you planning on pounding out at a time? Will you run a brake on the rifle? A 300 unbraked I'm uncomfortable after 20 rounds, compared to an unbraked 7mm mag which I can shoot 40-50 rounds no problem.
My .308 I shoot 70-80 rounds and the last shot is as pleasant as the first. I've seen more than one guy develop a flinch with a magnum.
