Unit of measure to reflect the number of balls inside a shotgun shell. Expressed as the number of balls from 1 lb of lead that can fit in the barrel. 12-gauge barrel: 12 x 0. 727 inch balls = 1lb. Larger gauge = narrow barrel (smaller balls) Greater velocity = more damage: double the weight of a bullet (2x power, double the velocity of a bullet (4x power) Components divided into these categories: explosive material/propellant, projectile, cartridge (case) Full metal jacket: the lead is surrounded by metal.
