[QUOTE="Kevin Thomas, post: 801743, member: 15748"] Edd, Might also add that yes, the barrel makers do use an abrasive when they do the final lapping on a barrel. An abrasive and a lot of hard earned experience. They're going to take a dim view of a customer trying to "improve" the job that they did at the shop. Some years back there was a firm that offered an "electropolished" micro finishing treatment on "their" barrels. The original barrels were made for them by Ken Johnson, of K&P barrels, after which they did their micropolishing magic. When the marketer wanted to list them as being made by Ken, he was adamant in keeping his name out of it. As he explained it to me at the time, the barrels were "his" when they left his shop. As soon as someone (even a full-on vendor of a process such as this) does something else to the inside of those barrels, they're no longer "his" and he didn't warranty anything after that. I tried a couple of the barrels that were being marketed by this firm, and despite major claims of enhanced accuracy and greatly increased barrel life, they performed no differently than any other barrels. After hearing such claims for the past 30+ years, yes, I've become pretty jaded. [/QUOTE]
