Having had a set of damascus barrels honed for removal of pits, and seeing how little he had to remove to get rid off all but one of them completely, I would just have to say you need to rely on the services of Mike Orlen, or someone in his expertise range with barrels. (Maybe Dean at Skeet's in Tahlequah, OK?) He can evaluate them and tell you if he thinks they will clean up with a light hone, then if you want him to he can do them while they're there.
