I know I am just taking pot shot stabs in the dark but I am in the begging of collecting some information. Here is another post I found from John Kort referencing early smokeless powders found in the 30-30.

Historically speaking, from 1896 to the mid 1920's, .30-30 "Short Range" cartridges "For small game where the more powerful cartridge is not necessary" were offered as a standard factory loading. They were factory produced .30-30's with 100 and 117 gr. lead bullets to replicate .32-20 performance. Being somewhat of a .30-30 nut, I have done an exhaustive study on this interesting class of .30-30 cartridges. I acquired a number of specimens to dissect and test and all were loaded with anywhere from 4.4 grs. to 9.0 grs. of various early smokeless powders loaded loosely in the cases. Before placing this ammunition on the market, the ammunition companies would have done some exhaustive testing to make sure there would not be any problem, and .........there wasn't. Here are some of the earlier .30-30 "Short Range" loadings: 100 gr. lead 4.4 Bullseye / 5.0 Walsrode / 9.0 DuPont No. 2 Bulk Smokeless 117 gr. lead 6.0 Ballistite / 6.0 Walsrode / 7.0 Schultz / 7.0 Marksman In testing equivalent charges of current powders, I found these to be ballistic equivalents of the early smokeless powders in these loadings: Walsrode & Ballistite - 4756, Trail Boss Schultz & Marksman - Blue Dot, HS7, 571 DuPont No. 2 Bulk Smokeless - 2400 Unique, Universal and 800X produced a bit more velocity in equal charge weights than 4756 and Trail Boss, but are very close equivalents in the charge weights above. Cartridge history sure is interesting! John
