I have both, and really, I pretty well grab either for deer. One thing I see, is generally the 7mm08 has slightly less recoil. I generally shoot 165gr bullets for my 308. never could get 150gr to shoot as well. And generally shoot 140gr for my 7mm08.

But then again for deer, I have a 270win, 06, 45-70, 30-30, and try to take them all out at least once during hunting season. All of them kill deer very good.
