Joe's head is empty. Joe consistently says things that let you know Joe still isn't all there, and never will be at his age. Fire both barrels? You would hit the same thing you'd hit with one barrel, and one barrel with any ga. shotgun, and say within 30 ft., and no one can survive a shot in the body cavity using a basic bird load...load of #6's let's say. No need for buckshot. But a shotgun is a good home defense weapon.
