I have three Damascus barreled guns. My Joseph Lang was built in 1866 and re-barreled by James Woodward around 1872, my J&W Tolley was built around 1887 and my Parker in 1891. I shoot all three of them with low-pressure smokeless loads, either RST or my reloads which have been pressure tested by Tom Armbrust.

I'm comfortable shooting them with these loads. In fact I've put over 3,000 cartridges through the Lang in the 3 1/2 years that I've owned it, about 500 RST's and somewhere North of 2,500 reloads.

If the barrels check out in good condition with adequate wall thickness I have no concern about shooting Damascus barrels with appropriate ammunition.
