Have been working on this as it is relevant to Pattern Welded barrels which were available from the U.S. makers into the 20s
https://docs.google.com/a/damascusknowle...fUOZEFU/previewand which have now clearly been shown to have been both proved and intended for use with Nitro powder
https://docs.google.com/a/damascusknowle...ZhIiY62Hx4/editSo far I have the hang tag loads as follows:
L.C. Smith 12 gauge.....3 dram..........1 1/4 oz. shot (1887 - about 1920)
................3 dram..........1 1/8 oz. shot (after 1920)
16 gauge.....2 1/2 dram......1 oz. shot (introduced 1896)
20 gauge.....2 1/4 dram......7/8 oz. shot (introduced 1907)
From
Remington hang tags, until at least 1899, guns were targeted with a black powder load of 3 1/2 Drachms F.G. Powder with 1 1/4 ounce of #8 chilled shot.
By a 1908 hang tag a 12-gauge Remington Hammerless was targeted with 24 grains of Infallible in a 2 5/8 inch UMC Nitro Club shell with 1 1/4 ounce of #8 chilled shot. The maximum recommended 12-gauge loads was 3 1/4 drams of bulk smokeless or 26 grains of Infallible or Ballistite dense smokeless powders.

The 1913 catalog
Lefever Arms Co. catalog gives recommended loads in 12ga going up to 3 1/2 Drams Black or Equivalent of Bulk or Dense Smokeless powders with 1 1/4 oz. shot, or 28 grains of Laflin & Rand Infallible. (Courtesy of Mark Ouellette) What was the hang tag load??
1900
Parker hang tags stated that 12g 2 5/8” chambered guns were patterned using 2 3/4” shells with 1 1/8 oz. No. 7 chilled shot and 40 grains (3 1/4 dram) of DuPont Bulk smokeless powder.
Could you please check other maker's catalogs or hang tags for the recommended loads
and thanks!
