Just finished watching a new series on Discovery (at least I didn't see it before) called "Human prey." In this episode they showed two guys that survived (albeit not quite intact) encounters with a hippo and a charging grizzly. The hippo was extremely impressive, particularly when they showed it charging after a boat. My question, however, is regarding the second story, the young guy attacked by the bear. After being torn up somewhat, he managed to reach his rifle and despite his injuries he killed the grizzly with one shot. They showed him load his rifle in front of the camera, but there is no guarantee, of course, that it was the same rifle. Even though, has anyone noticed what it was and what caliber it was?
