I don't hunt big game with a .308 Win but you surely could. Using a 168g bullet your limited to about 800 yards max due to energy left at that distance. We hunt a few chucks long range with it. We've killed chucks out to 1000 yards with a .308 Win. We mostly use 168g A-max and out to 600 yards the chucks damn near implode. Your range estimation and drop chart need to be dead on with this caliber as muzzle velocity is normally only around 2700 fps and bullets drop quckly the further out you go.
