full scale 12lb mountain howitzer 4" rifled barrel, 42" wheels solid oak carriage(prarie /pack carriage) built as close to 1865 mil specs as we could. shoots 100mm bocce balls at approx 800fps with 1/2 lb of black powder generating about 25,000 ftlbs of energy -----thats a lot----, with a little practice can be pretty accurate at 400-600yds, I moved and have no place to shoot it. makes me sad to see it just sitting in the garage, you won't find one like this anywhere.
