Greg Brush, an Alaskan fishing guide, was ambushed with no warning by a charging bear. All he had time to do was pull out his .454 Casull and fire as fast as possible, while falling backwards after tripping on a branch. The Anchorage Daily News reports:
“He drew a Ruger .454 Casull revolver. There was no time to aim, barely time to squeeze the trigger. He’s not sure whether he got off two shots or three, but one proved fatal.
“Total luck shot,” he said.
“It doesn’t get any closer. He slid by me on his chin when I shot him,” Brush said. “I was backpedaling as fast as I could. I wasn’t even aiming. I tripped over my own feet as I pulled the trigger.”
He estimated that the animal weighed 900-plus pounds, and was 15 to 20 years old. It had grass packed in its molars and little fat on its bones.
“It was starving to death and saw an opportunity,” Brush said.”
