The late 19th century was an important development period for the 12 gauge shotgun. Barrels were being redesigned, choke boring appeared, and external hammer double guns became hammerless. At this time, 10 and 12 gauge ammo were considered efficient all-around gauges, but around the 1890’s , 12 gauge ammo began to solidify its place as the best all-around option.

According to Jack O’Connor’s book titled The Shotgun Book, by the 1950’s 12 gauge ammo had about 50% of the shotgun market, while the 20 gauge and 16 gauge ammo had 17% and 25% of the market respectively. As sales declined through the 1970’s, manufacturers developed 3 ½" shells, which carry 1 3/8 ounces of steel shot, to improve the 12 gauge’s capability as a waterfowl shell.
