A friend I went moose hunting with this year went on the Kodiak island hunt with a bow. He had a .454. But he was hunting Blacktail. Anyway, a grizz was stalking him for 1/2 mile. He was scared to death, so he dropped the deer but the bear walked right past the carcus. Well its not so easy to kill a bear up there it appears. You have to prove that the bear was a threat. So wisely he didn't shoot. He said he couldn't hold that .454 steady enough to get a head shot. So wisely he didn't run, and stood his ground as the bear smacked the ground and roared and finally gave up and went backt to feed on the blacktail. He swears that next time, if he would ever go back, a slug gun in the only thing he will carry. I trust him greatly and don't doubt the story. Cause all he has left of that blacktail is scull and horns.
