I just shot a sow Black Bear at 70 yards in Northeast Washington and it only made it about 40 yards and let out a big breath that sounded like a deer blowing. It was a heart/double lung shot. Bear are tough, but if you hit the right spot they go down hard and quick. Just don't take questionable shots on ANY bear. They are powerfull, fast, and quiet animals. They have alot of fat and are very greasy, so if you make a bad shot the blood trail is usually poor, and you likely will not find the bear, or worse it will find you.
