Agreed, pretty rare, but then it depends on where you live.
I policed Anchorage AK, we constantly got calls of bear and moose hanging around school bus stops.
We didn't carry "African Rifles" we carried shotguns and pistol/revolvers. Some carried slugs which would work I guess but I don't like shotguns in police work (thats just my opinion).
I carried a 357 with LSWC bullets. I didn't shoot any bear but I've shot several moose. The 357 worked for me. When these animals are a hazard they are normal close. It's pretty easy to hit the base of the neck with a revolver.
