If you shoot an Elk at 800 yards with a .338 Ultra mag pushing a 300 grain Sierra matchking at 2770 Feet Per Second, its about the same as shooting an Elk at 300 yards with a 180 grain partition out of a 30-06. If your a good shot,use the right equipment and know your bullet drop Its very ethical.

If you lopping a light bullet with holdovers guessin it might hit the criiter and hoping your bullet will have enough kinetic enerhy to kill it than thats very unethical.
