Cast using naval gun bronze from an original mid-18th century pattern with the trunions mounted low on the tube, our gun is priced thousands less than the cost of a finished bronze barrel sold elsewhere with the same casting quality. The barrel comes rough cast and bored but without the touch hole drilled and can easily be finished in 2 to 3 hours using a die grinder with Scotch-Brite pads, metal files, a wire wheel and some emery cloth. The total length from muzzle to cascabal is 23" and the barrel weight is 55 lbs. The unlined barrel has a concave breech with a breech wall that is 1.3" thick and a bore size of 1-3/4". Proudly made in the USA.
