In 1925, the "standard" 20-gauge shell in the U.S. was still the 2 1/2 inch case loaded with a max load of 2 1/4 drams equiv. and 7/8 ounce of shot. The Western Cartridge Co. had just introduced their Super-X load in 20-gauge a couple of years earlier, put up in a 2 3/4 inch Field case with a max load of progressive burning smokeless powder and 1 ounce of shot. Even the 3-inch 20-gauge shells, from back in the days of the fabled Widgeon Duck Club Parker Bros. guns and the J. Stevens Arms & Tool Co. No. 200 pump, carried a load of 2 1/2 drams equiv. and 7/8 ounce of shot. A standard Skeet load today!!
