Shoot it and don't look back. It's SD is still above a 150 in .308. You will be hard pressed to keep it in an Elk. Frontal diameter in the .338 is an advantage no mater what the energy is. Large frontal area plus magnum velocity seems like a good combo to me. People always hate on light weight .338's but seem to love premium bullets in 165's or 150's in .30 cal. Strange.
