I'm sure this is true, and the .22LR has killed many people. There are abundant stories of large bore handguns failing to stop a bear. Last summer in my neighborhood a homeowner shot a modest sized black bear in his house with a .44 Mag. The bear shook it off. Yes, a properly selected round properly placed could would have stopped the bear....this does not mean that a .44 Mag is a good choice in serious bear country. Which is why I carry a .454 Casull loaded with Buffalo Bore hard casts.....and I'd love to pick up a 45-70 Guide.
