I previously mentioned that I was experimenting with a Black powder load for my Fox double. I used some paper hulls 90 grains of 3F and 1&1/4 ounces of #6 shot. Hard card wad over the powder and a fiber wad on top then the shot. I tested it at 30 yards using a facsimile of a turkey's head. The pattern was a little left but both shots I fired would have been killing shots, as there were pellets to the brain and vertebrae. Only a couple of pellets though in each, with a few more that would have caused trauma. Definitely is not anything like a TSS pattern. Stout kickers too! I also tested the exact load in a plastic hull, and for some reason, it patterned poorly. I think I'll try a modification using a plastic shot cup on top of the hard cardboard over the powder wad.
I only tested the left full choke barrel.
