how bad is bad ?
I picked up an old 12ga side-lock double SxS made by the "American Gun Co." It has Damascus barrels, and I wonder if anyone can tell me what to look for in terms of its soundness to shoot with BP. Barrel has some pitting which wasn't apparent until I cleaned it. I've been told if the barrels "ring" when struck with a wood block, that's a good sign, if they sound dull or "thud", that's bad. What's the standard for acceptable pitting ?
