Yeah, totally! A black bear can certainly be plenty menacing, especially a sow with cubs. They are equally unpredictable and can do some serious damage in their own right. I learned that fact many years ago (1982) up in southern Manitoba, where beekeepers were allowed to harvest rogue black bears on-demand, and a 12-gauge can certainly be persuasive. As a matter of fact, I think I read somewhere (not sure about the accuracy?), that the U.S. National Park Service (at Glacier National Park), uses 3" magnum 12-gauge loads of rock salt for habituated grizzlies pestering people at park campgrounds and trails. And I don't doubt it. The right load of salt in the face, or the ass, can leave a mark!
