Is it possible to damage or affect the accuracy of a barrel by black nitriding it?

[QUOTE="bamban, post: 1794335, member: 17722"] I spin up the AR15 barrels (donated Shilen blanks) for our TX Juniors High Power Team, I send their barrels, along with some of my friends' barrels to the Nitriding operation in Chapell Hill, TX. To date, I must have sent close to 50 barrels for the treatment. The first few ones I tested for precision before and after, did not see any measurable change. Longevity? I sort of coerced a good friend to re-barrel his service rifle before going to Camp Perry last summer. He had 10741 rounds through the Nitrided barrel, the last 600 yard match he shot was 198-10, he was burned for an 8 on a let down. Untreated button barrels we typically pull them out at 3000-3500 round range. I am shooting a few nitrided barrels right including a M40/M24 countour 300WM in my M24XX clone. So far I have not seen any dedgradation in precision after over 500 rounds shooting MK248 Mod 0 ammo. Will report some Teslong borescope pictures in a few days. Edit: One of the nitrided junior barrel will be pulled out shortly. It has close to 6K rounds. The shooter earned LEG points on his last match and a mid 190 at 600 yards with it, but he reported having to chase the throat for his long line ammo. His dad verified the claim, so we issued him another barrel. I will get the old barrel to see how bad the erosion is. Cleaning after the treatment, the best method we found was to remove all flash hiders, and barrel extensions (yes, the BEs will loosen up by the treatment) and leave the barrels underwater in an old large cooler for a couple days. You can see the brownish Nitriding residue ooze out from the bores. The residue is water soluble. [/QUOTE]
