I also remember reading,and I believe it was here, regarding owners of damascus barreled guns finding minute holes right through their barrels due to inclusions that were present from the original forging process. I think they had been shooting these guns for years without ill effects.

Years ago, a friend and I were looking at a British 2" 12ga he was thinking about buying. Couldn't find any real issues other than some very small exterior pits (not holes) in the barrels, within 6" of the muzzle. We both thought the gun should be rejected on that basis. But after thinking about it a bit more . . . wait a minute! People shoot guns with REAL holes in the barrel out by the muzzle (ported barrels) all the time.
