The above is pretty good info.
I've shot one with a 280 and a couple with the 7mm Rem mag. I've only used the 160 Nosler Partition on bear in those two cartridges. They were never found wanting.

On a spot and stalk hunt I would stick to the controlled expansion bullets. Black bears aren't particularly hard to kill but most folks shoot to far back . A traditional behind the shoulder shot usually results in a gut shot bear . Their vitals are further forward than most think
D6native,
I'll have to respectfully disagree with your statement about the vitals on a bear. I would say the opposite. A shot to the shoulder leaves very little margin for error to hit the lungs or heart. If the bear happens to be quartering away when you think it is broadside a shot to the shoulder isn't going to hit vital organs. It happened to me once. All I got out of that deal was a sick feeling in my gut and a piece of shoulder bone. The next year I aimed about 4 inches behind the shoulder of my broadside bear and put the bullet there. Result: double lung shot bear that ran about 70 yards.
