Of course, the only bears I've seen round here are koala bears, so I may not be an expert, (lol) but I've killed enough scrub bulls, brumbies and big pigs with the .45/70 that I reckon it should deliver the goods on a bear. I remember many years ago reading an article buy a bloke who took his guide gun to Africa, and shot a cape buffalo with a 540gn lead bullet. From memory, he broke both shoulders and the bullet exited completely.
