Anyone on here ever tried this? A friend clued me in on it, so I gave it a try. I also watched some YouTube videos on it, as well as reading a lot about it. The 444 brass was a fit for my old Essex single shot 410. I used a large pistol primer, H110 powder, a Claybuster wad, and 1/2 ounces of shot, with a cardborad wad over the shot. There was a lot of fouling left in the bore, which I believe may indicate a not so tight seal over the powder.

I wouldn't want to depend upon these to defend my life with, but in this day and age of 410's being hard to find, they'd work in a pinch. I probbaly wouldn't fool with doing this, but I had about 5 pounds of #6 shot and a half bottle of powder, as well as some primers, and a lot of time on my hands. If anyone else has tried this, please let me know what your experiences were.
