That's a great looking powder horn Shovelbuck. You do good work. I bought a semi-finished Flat Horn from someplace online..Crow something.. Anyway, I finished it and scrimshawed a gobbler on the front and back. One with India Ink and one with watercolors then sealed to keep the colors. I'll post a picture of it when I get a chance to take a good picture.
I don't use it for powder, but for shot when squirrel hunting and will use it for dove if I go this season.
