Pastor of my dad's church in Anchor Point, when he lived there was hunting deer on Kodiak with a .243, when a bear charged. The bear ran over him as he fell backwards. Somehow he ended up on his knees with the rifle in hand. It had been slung over his shoulder. One shot dropped the bear. I don't recall where he hit it. But, on that day the .243 was a stopping rifle. I believe the story appeared in Alaska Magazine as told to Jim Reardon. IIRC.
