Board is 20"x18".
Shot at 30 good strides.
1ounce plus. #7 mixed.
Powder, 70gns of, well, you decide but to me it looks very close to 4f.
Wads were four thin overshot cards. One on top.
Dont dismiss the finer grades of powder just because someone says, "it doesn't work" or "its dangerous", "pressure is to high". "Blows patterns", "its to fast", blah blah blah.
