Home Forums Hunting & Shooting General Big Game Is a .308 just as capable of being a 400 yard rifle as a .270 or .30-06?

Never been one to shoot over 200 yards, but I've increasingly been in cut over areas where shots out to 400 are possible. Yes, I know A LOT of practice is required for shots past 300. Just wondering if a .308 is really giving up much to a .270 or .30-06 from 300 yards to 400 yards especially with all this new ammo that's coming out.
