Years ago I used to bear hunt in Ontario, Canada and I carried a Ruger Super Redhawk, the early model with the extended lug and I carried, and I used to carry a 240 gr. JHP. Now if memory serves me correct, and it's been many years but I carried 3 JHP and 3 hollow points. If you ever hunted bear you always want to have a back up with you. My philosophy was when you hit a bear you went for the chest/front shoulder area and regardless you hit him twice. Once to break the shoulder and the second for insurance. Then when you got up close and if he was still breathing, use your Redhawk. I had a friend who hit one once and he went down immediately but jumped back up and ran through some muskegs and disappeared. In Ontario back then, once an animal was hit, you were obligated to find him and do the right thing and make sure he died. There is no sense in hunting if you are not going to use the meat. I have taken some bears, black bears, and they have a tenacity and can move very fast. I was lucky and never used my Redhawk but when approaching, I always had my pistol out and did a very slow approach. Many wish to save the skull however it's more humane to not let the animal suffer and if not sure, use your Redhawk. I never had to use mine, however Sh=t can happen and not worth the risk. This is just my personal experience and that's the only advice I am able to give.
