I don't know Tren about the shotgun and bear. Maybe a small black bear...but I'd still feel better with a 30.06, even a 7mm at range. Bears have a slow metabolism and as such...die slow as well...leaving them with enough time to take a swipe at your ass with those 43 pound paws. Their hide is thick and they have a nice layer of fat to slow down a slug.
Maybe if you were jacked up on tren you could take it out with a k-bar
Now...if you want a rush...take a big predator down with a bow at 15 yards...that'll make your nuts suck up in the sack
