Have a friend that wants to start deer hunting and short range target shooting, he asked what caliber rifle he should get. All ammo will be purchased. The last 2 years about the only ammo you could consistantly buy was 308, it seemed to be everywhere. So choices would be a bolt action 308, 6.5 creedmoor, 270, 30-06, 7mm-08 (not the easy to find ammo). Being a new shooter (fairly big guy) do you think the 308 would recoil to hard and what do you suggest.
