I never said you couldn't take out an Elk or Grizzly with the round. Heck, this round has taken large African game. However, I wouldn't choose it to be my primary hunting rifle with larger game like Elk. The ballistics just aren't strong enough for a reliable kill and there are so many other more preferable rounds for such game. And I do plan on hunting the heck out of my rifle for black bear and white tail.
