"In the Northwest Territories and Nunavut Territories there are also tundra grizzlies. These are about 1/3 the size of polar bears but a lot more aggressive. On a caribou hunt my Inuit guide carried a .338 Winchester Magnum, just because of the angry little tundra grizzlies. He used a .243 to hunt polar bear."
MuleDeer quote.
Ditto on that. I knew an old Inuit hunter who swore by the .243 for Polar bear. He said that they NEVER charge - when shot.
