270, 280' 308, 30-06 7mm-08. Any of these would work well. If you can hack a little more recoil, the 300 WSM or 300 Win Mag would also fill the bill. I would suggest that you try to fire some of the Magnum rifles before you lay out the money. You may find that you get no shooting enjoyment from the hard kickers. I shoot for fun not for punishment but thats just one mans opinion.
