Here in my region (MT/WY/ID) many if not most of the fatalities the past ten years have been hunters, i.e., armed humans.

Of course, it had nothing to do with amament but more about actions. Hunters usually go about their business with stealth which can lead to some accidental encounters. It's my perception that most of the truly serious injuries from gizzly 'attacks' were suffered by hunters as well. There's been at least one death when the hunter was killed while tending to his own kill. Bears find gut piles enticing and there is some anecdotal evidence that some griz are now attracted to gun fire.

It takes a very well trained individual with very steady bearing ( ) to get off a stopping shot against a charging grizzly. And a lot of luck.
