If you are more interested in hunting deer, I would say the .308 Winchester. I am sure the 7-08 is just fine...and is a little flatter shooting. However..I have always been 'old school' for deer...larger caliber/heavy bulllets for whompability w/ less meat damage. I would prefer a .308 180 gr bullet @ 2500 fps over a 7mm 150 gr bullet at 2700 fps. But my main reason would be the availability of cheap milsurp ammo. Any 7mm-08 ammo that you find is going to be premium priced specialty ammo or you wil have to re-load for it. I re-load for about everything that I shoot, however, it is wonderful to be able to buy cases of ammo for plinking, or to have for an emergency stash.
