I could care less how much muzzle energy a handgun round has. All I want to know is, (A) can I shoot it accurately, and (B) if properly placed, will it penetrate straight and deep enough to stop the critter? Odds are, if a handgun round is so powerful that it can shock a bear to death(whatever that means), there's no way that I could stand practicing with it often enough to make reliable hits with it. JMO/YMMV. For folks that can shoot the hand cannons quickly and accurately, go for it, you have my respect!
