Generally agree, but I do know a guy who shot a Griz during his black bear hunt in Wyoming.
One shot to the chest, Grizzly dropped on the spot.
Seems Griz are cannibals, this one wanted the black bear quarter he had already carried to his truck.
Black was shot with a 30-06, he was surprised by the Griz and did not even think of the rifle as it had been put away after taking the black!
Game warden showed up about then, curious why he heard a shot after legal hunting hours.
Hunter explained, showed him both bears.
Warden gave a choice of which he wanted to keep, the other went to the local tribe.
He has a nice grizzly rug in his den now.
Yeah, luck happens. I know a guy in Montana (an old hunting buddy) who dropped a 6 point with his 22LR (it’s legal in Montana). Has a great trophy on his wall, and you can feel the hole right in the middle of the forehead where he tagged it with the little round.
Yeah, luck happens, but I prefer to not count on it and increase my odds with as much firepower as I can carry...;)
