I would definitely have to say Shotgun. #4 buckshot is essentially 27 lead balls of .27 caliber headed downrange at 1200 plus feet per second with each sqeeze of the trigger from a 2 3/4" shell
Shotgun. Each shot is equal to a burst of fire. More socially acceptable. Shooting someone once with 12 Ga. sounds better in court than 8 or so times with a 9mm.
