You’re right welcome. When I lived in Alaska I was charged by a young black bear. I shot him in the head with a .308 rifle from a distance of about 50 ft followed by two successive broadside shots through the chest. It took a fourth shot to the front of his chest from about 20 ft before all activity ceased. This bear was tiny compared to a Kodiak Brownie and I was using a high-powered rifle. Yes, amped up bears are hard to stop.
Must of missed the brain or the bear was just reacting from the brain hit.
