Around 1913 or 1914, The Small Bore Shot Gun pamphlet put out by Parker Brothers stated that the 2 3/4 dram, 7/8 ounce load was tested for velocity, but "It is not recommended by us, or loaded by the loading companies." However, the order for 20 gauge #149,975 states that the buyer wished to have the gun patterned with one ounce of #6 and three full drams of powder in three inch shells. I assume that my old 20 gauge #153,333 was patterned and ordered for the same shells. Hedderly's old 20 gauge A-1 Special 32" gun was ordered to be chambered 2 3/8". Hedderly's 16 gauge A-1 Special 32" gun was chambered at 2 7/16".
