I don't anymore, I did back in the 1990's. Had a Dixie Gun Works 12 gauge percussion SxS. I loaded a volume equivalent load, 1-1/4 ounces of 6's and I think the same volume of powder was right at 80 grains or 3 drams. I had a powder flask that threw 3 to 3-1/2 drams, if I was feeling sporty I would shoot 3-1/2. Best patterns were with two 1/8" hard cards over the powder, no "cushion" fiber wad. I tried plastic wads, just weren't any fun using them in a 19th century replica gun. Sold that gun along some others during financial problems. Wish I hadn't. Interesting to use except for the cleanup.
