Dr. Herrero is Da Man when it comes to bear behavior and attacks! I discuss his book briefly on my links page.
The rifle used to shoot the bear off me was a .300 mag with 150 grain Barnes X's. Those are awfully light but you can't fault the penetration of that bullet design. The bear was hit approximately in the liver or rear rib cage from the side. The second shot was into her front somewhere (he just saw brown in the scope as she charged and pulled the trigger). A biologist named Larry VanDaele tracked her for several miles the following day until she quit bleeding and he lost the trail. That same bear was almost certainly the same one that attacked another party of hunters nearby 3 days after my mauling. These guys were loading deer into a skiff when the bear spotted them from a hillside several hundred yards up and just charged - they bailed into the skiff and the bear went right into the water after them. They decided to hunt elsewhere.
