[QUOTE="DoctorPMN, post: 1736783, member: 106383"] Rich, cryogenics was the process I was thinking of when I mentioned stress relieving. Were your 50/50 results with salt bath nitriding treatment obtained on top tier barrels (Krieger, Bartlein, etc.) that were hand lapped prior to nitride/cryogenic treatment? As you may know, one of the manufacturers of AR15 barrels (AR Performance) has nitride/melonite treatment done on essentially all of his barrels. Barrels are very well thought of in that community. When using one of his barrels it is typical to expect <0.5" groups (100 yards) with barrel lasting several thousand rounds before accuracy begins to fall off. [/QUOTE]
