Thanks guys. I figure it would have to be big enough to hold together, as hitting the body , maybe breaking it down, is going to be more likely than a head shot. I'm in agreement with being a practiced shot, and I too don't trust a black bear ( the ones where I hunt are usually sows with cubs) at all. Its a big area that ranchers use for calving, so lots of predators around, from bobcat to teeth popping mama bears! ha
