My best friend was charged by a Black Bear while opening the back door of his cabin.
He opened the back door of his cabin at 8am with his dog standing next to him. His dog smelled something and started barking. The next thing you know, a 6ft black bear came tearing around the corner and went straight for him and the dog. The dog intercepted the bear about 10ft in front of him. For almost 30min the dog and the bear fought each other in the woods about 25yds from him. My friend had an 870 with buckshot but was afraid to take a shot at the bear because he was afraid of hitting the dog. Amazingly the dog wore the bear down and the bear took off. The golden retriever ran circles around the bear and kept biting him the butt.
What do you do if you have to use that gun in defense of another person? What would you do if the bear was chewing on someone and you wanted to shoot it in the head?
