Good rifle. Both my son and I hunt black bear with vintage 1895 Marlins in 45-70. We both shot black bear this year with them. His dropped right where he shot it, mine went about 30-40 yards into the jungle of Maine woods; really tough dragging/getting them out of that stuff. My shot was a broadside shot, took the top of the heart off like a hand grenade hit it, but....it still went the distance. I shot one two years ago, it turned and walked about 10-15 feet and dropped, tried to get up a second and third time, when I shot it once more. I am using Barnes 300 grain TSX FBHP, they perform perfectly. That 405 grain bullet ought to get the job done in good shape too. I would put the 45-70 up against anything that walks with continent with confidence.
