This is my first attempt at anything black powder. Looked at pictures on the WWW, ordered a horn on ebay, and here is the product. In spite of reading warnings from experienced builders, I ended up drilling a hole out thru the side while drilling the spout, but some shavings and epoxy hid it pretty well. The spout is deer horn, and so is the threaded plug on the back end. The wood is aspen turned green by bark beetles and stabilized/sealed with epoxy on the inside, and super glue on the outside.
