first off establish the chamber depth, as many early (pre 1900) had 2 5/8" chambers
I have one old 10ga shell in my collection - a UMC Co. Nitro Club; paper 2 7/8" roll crimp, top wad marked DU PONT UMC Co.
3 1/2 - 1 1/4 - 3 with these markings I have to believe it is a Nitro Load
But the; 3 1/2 dram - 1 1/4 ounce is a load I would try. of course target or species will determine load particulars.. quail would be way different load than say geese or fox
1 if not 2 .135 card wad (over powder), fiber filler, maybe a .135 card to support shot, shot, then a .050 over shot wad. elmers glue, or water glass to glue in overshot wad. I don't roll crimp my brass case loads..
most old Black Powder authorities advised equal volumes of powder and shot then filler wad at least equal to bore diameter..
