With the introduction of Bulk and (slightly later) Dense Smokeless Powders, the U.S. gun, shell and powder makers provided load recommendations, in catalogs and some on hang tags

Standard loads found on L.C. Smith hang tags:
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)
I haven't seen a Hunter Arms hang tag after the 20s specifying the standard loads
