I think the example given of the guy with the Ruger was an example of killing the bear with lead poisoning. Sounds like it took two magazines but fortunately for him two rounds found their mark on vitals.

All the .22 examples were with black bears, too. I'm curious what the outcome might've been against an 800 pound Grizzly as opposed to a much smaller black bear.

I know a .22 will kill a black bear. Mrs BG and I found a dead black bear just outside the fence line of our Bailey property. Cause of death wasn't obvious. I searched the carcass with my metal detector and found one .22 LR LRN slug. Really pissed me off that someone shot that bear with a .22 and left it to die what was most likely a slow and painful death.
