bigdog---well the gun is in pieces now. All the metal parts are at home and the stock is with me at work so i can get more coats of tung oil on it faster. I will need to weight what I have here and then weigh the metal parts with my new home scale. But my guess is about 9.5 to 10.5 pounds. That Blunderbuss barrel is pretty beefy but it is ONLY 20 inches long. My 50-90 double rifle weighs about 9.5 pounds and I can tell you that the hot loads for that gun with 525 grainer Woodleigh round nosed boolits are quite formidable. I got the first coat of Tung on the stock yesterday but the humidity was up and it is still tacky so I will net get that second coat on this AM as I hoped. But I finally got the deep dark rich red colour I wanted. I am feeling like I am rounding the last corner on this build. But as they say you can't count your blunderbusses until they are 100%. Done. haha
