I can vouch for the effectiveness of a .510 450 gr bullet from a 50-70 on a 400+ lb black bear. Launched with 65 grs FFg, it penetrates and breaks bones at 100 yds.
The game cutter that did my last such bear handed me a recovered bullet with a flattened nose that gave the bullet a cross section measuring 5/8". It had gone through the heart and buried itself in the off shoulder. He went down and stayed down.
Slugs and big bullets work on bears.
