I have a Joseph Lang non-rebounding hammer gun with Damascus replacement barrels by James Woodward. The gun was completed March 6, 1866 and I have no clue how much it was shot before I bought it. I've shot about 6,000 7/8 ounce loads at 1050 fps, both RST and my reloads, through this gun since I bought it. I've not had a single mechanical issue with it and when I do my job clays break and quail die. Too bad it does it's part much better than I do mine.
