Paper Shotshell Lengths
In reviewing old Union Metallic Cartridge Co. catalogues and price lists, the first time I see mention of paper shotshell lengths is in 1895 where they offer 10-gauge shells in 2 5/8 and 2 7/8 inch lengths, 12-gauge shells in 2 5/8 or 2 3/4 inch lengths, while 16-gauge is just 2 9/16 inch and 20-gauge just 2 1/2 inch. In the September 1896 catalogue they offer 12-gauge paper "Smokeless" shell in lengths up to 3-inch. All brass 10- and 12-gauge NPEs were offered up to 3 1/4 inch length. By the April 1899 UMC Catalogue things are really taking off and they've added 2 3/4 and 2 7/8 inch lengths to both 16- and 20-gauge offerings, and the 3 1/4 inch 12-gauge length in their "Trap" shell. By the May 1900 UMC catalogue the 3-inch 16- and 20-gauge length is being offered in their salmon colored "Smokeless" shell and their green colored "Trap" shell.
That pretty much covers paper shotshell lengths and when they appeared. So, by 1900 we had paper 12-gauge shells in 2 5/8, 2 3/4, 2 7/8, 3 and 3 1/4 inch lengths; 16-gauge shells in 2 9/16, 2 3/4, 2 7/8 and 3-inch lengths; and 20-gauge shells in 2 1/2, 2 3/4, 2 7/8 and 3-inch lengths.
From the 1890s into the early 1920s, these longer shotshells didn't carry a heavier payload than one could get in a 2 3/4 inch 12-gauge shell, just more/better wadding, which many serious Pigeon shooters believed to be an advantage. The maximum smokeless powder loads offered in the 2 5/8 inch 12-gauge shell and the 2 1/2 inch 20-gauge shell were a bit lighter than those offered in 2 3/4 inch and longer shells.
Drew,
Actually the 12-gauge Western Cartridge Co. Super-X load of 1 3/8 ounce of shot in their 3-inch RECORD shell wasn't released to the public until 1924 or 5.
The 1 1/4 ounce 12-gauge and 1 ounce 20-gauge Super-X loads in the 2 3/4 inch FIELD shell were released to the public in 1922 and the 1 1/8 ounce 16-gauge Super-X load in a 2 9/16 inch FIELD shell was introduced in late 1922 or early 23.
