Something to keep in mind, when trying to duplicate the old loads, is that the Super-X or whatever, didn't burst on the scene full grown. First it was just a progressive burning powder load in Western's Field shell for 2 3/4 inch 12- and 20-gauge and 2 9/16 inch 16-gauge, and the heavier 12-gauge 1 3/8 ounce load in the 3-inch 12-gauge Record case. Then by July 1929, you got Nash's beloved Lubaloy (Copperized) shot. Then circa 1931 Non-corrosive priming was added. Between April and September 1932, the Seal-Tite wad was introduced. By March 1934, the one-piece box. By March 1935, the Super-X was in its own steel-locked shell with a Super-X headstamp rather than the Field headstamp. By 1947 Western has added the Seal-tite base wad and replaced the over powder card wad with the Super-Seal Cup Wad. By 1948 the Super-X has the Super-Seal crimp.
As an aside, up into 1930 Western was still giving drams of bulk smokeless powder or grains of dense smokeless powder in their regular Field and Record shells. By April 1932 they are using drams equiv. The December 1936 price list states their New Chief black powder shells are no longer manufactured and are available subject to stock on hand. By 1939/40 they introduce the super-seal crimp on their skeet and trap loads, but these don't get applied to the Super-X hunting loads until a few years after WW-II.
