Pack bear spray? No, pack a 10mm pistol
When anything charges bear or man you have to get activated and fire accurately depending on distance within three seconds or so. In the case of a bear an instant kill is pretty ambitious. If the shot doesn’t turn it you are going to get trashed by a wounded pissed off animal. Maybe you get the bear or maybe he gets you. It’s better than going down without a fight but not much sometimes hunting and covered in elk blood or carrying trout back to camp, the brakes are off. Mom and the kids is a nightmare on paws.
