I shot mine last week with a 30-06. Exit hole about 3" by 3" at 200 yards broadside. It's all about shot placement. Doesnt matter what rifle, in hunting all we are trying to do is just punch a whole in the vitals of an animal!

This Alaskan cross fox was shot with a .300 ultra mag. ( i wont show you the other side though)
