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

[QUOTE="lowdowndirtybugger, post: 1794361, member: 88303"] I nitride all my precision barrels. In short yes you can mess one up if A: ANY copper at all in the barrel. Even micro amounts can cause small pits that wear over time B: you send it somewhere that either doesn't know what they are doing and just throws them into a big batch. On the other end nitride will more than double and in many cases triple your barrel life because the throat will resist wear from heat and friction. It slows the degradation process that causes fire cracking in the throat it also slows land erosion. Contrary to popular belief you can break in a barrel after you nitride it. It just takes longer... Alot longer Do not fire a barrel before sending it in as coppering is one of the biggest problems Send it to Controlled Thermal Technologies in Phoenix Arizona It will cost around 80$ They have done a dozen barrels for me and every single one came back shooting sub 1/4 minute. I have done this on .243 win (currently at 3200 rounds with only slight rounding to the edge of the lands and still at the same seating depth) 6.5 saum 2500 rounds with no visible or measurable wear 300 win mag 1600 rounds again no wear Others to early to really comment are 6.5 Creed (2), .223 rem, 308 win (2), 270 wsm, 7 rem mag, 6 br, 22br Do it right and you will be pleased but your barrel manufacturer will have a cow as they won't have as many resales......they just don't see it right. They get business from you being able to afford more builds because you're not replacing barrels every time you turn around. [/QUOTE]
