Six percent of people think they can beat a grizzly bear

Easier said than done if there is a Grizzly that close to you

See below.....no method is ideal but the bear spray isn't going to further anger a charging bear, that very well could be bluff charging......hit a bear with a non lethal shot and may turn out way differently.....

Easier than aiming a gun into one of the few, small spots that'll kill it before it mauls you.
