The in-between 16 is known as "The Gentleman's Gauge." To many hunters, the 16 gauge is the ideal ammunition for the perfect gun. A well-designed 16 gauge is closer in weight to a 20 gauge, with a shot payload nearer the 12 gauge, and patterning that bests them both. Like its most revered predecessor, the Browning A5 16 gauge is built on a smaller, lighter receiver for reduced weight and a sleek feel in your hands.
