That is one tough dude. And lucky. Don't know as I'd have fared as well with my Buck 105. They have some big black bears in the upper Mid-west.
I've seen a couple hunting up in northern Wisconsin. A few years back shot a buck, which bounded into a large slashings thicket. I was waiting for my partners to come up and then we'd go in and find him, or one of us would shoot him if he jumped up. Just before we went down the hill and into the thicket, what do we see but a couple hundred yards out was a big ol' black bear, heading into the thicket from the other side. Fortunately, we all didn't meet in the middle. My buck stood up just inside the edge of the thicket, my father-in-law shot him and I dragged him out of there right quick.
A couple years later I was sitting on the ground just after shooting light, scooted up against a brush pile on top of this little knoll, and I hear something coming through the brush off to my left. Didn't sound like a deer, but was sure no squirrel, just sounding like it was crashing through the brush. Sure enough, about 10 yards away out comes a very small bear, and walks right up to me. At about 15 feet he seems to suddenly realize I'm there, let's out a "hooof!" and spins around and ambles off. Meantime, I'm wondering when mama's gonna come and take her ire out on me for messing with her baby, but she never showed up. (Or, more likely, was pretty damn close, like behind me, but I never saw her.)
Next year, and since, I've seen a lot of the hunters carrying revolvers or .45s along with their rifles. I'm told the bow hunters in the area, who are out before the gun hunters, when the bears are more active apparently, pretty much all carry heavy handguns.
