I've heard that someone killed a polar bear with a 22LR...
That has probably happened... but you may be confusing the story of the WR interior grizzly which an elderly Native woman killed with a 22LR.
Interesting thread, the more I think about how big, fast, and how tight the cover could/can be hunting these great bears, leaves me thinking hard about my 338 Win Mag and 250gr A-Frames or Partitions, no need for me to scrimp ; ]
