When I am out in the woods with grizzlies in Montana, where I live, I carry a 44 mag with solid lead bullets, but the most important thing to me when up against a big bruin would be penetration. Just any lead cast bullet would not do because they are too soft and they flatten and do not penetrate as well on tough hided game. I use hard cast bullets that will not deform very much and so will penetrate. A friend years ago shot a grizzly at a few feet with a jacketed bullet from a 44 mag 5 times behind the shoulder. The jackets separated and the lead only penetrated 3 inches! Not what you want.
