[QUOTE="Trickymissfit, post: 476425, member: 25383"] I don't actually know a lot about that process, but gather it's really a coating (maybe like TIN). There's been a good bit of discussion about it on Benchrest Central. The thing that bothers me about nitride is the 900 degrees of heat, and I never seen anybody attemp anything in stainless steel. Plus (with some grades of steel) I've seen as much as .0009" shrinkage, and almost the same in growth with other alloys. Now I've had some barrels in the past that I wish I could shrink about .0005", but I also know that when the parent metal shrinks, it shrinks all the way around. Thus opening up the bore. Then there is a warpage issue from not being able to suspend it correctly. I'll probably be sending him a barrel this year (a Savage 6/250AI barrel). If you just want to try nitride, be sure to spec gas treatment! gary [/QUOTE]
