It was a good barrel. Very accurate. If there a rack of rifles, spotting the LWRC's is easy because nitride barrels have a very distinctive look
And Robinson Armament found that nitride can make an M&M effect on barrels where you have this very hard outer shell, but very soft inner core, which is not a good thing when the barrels are pushed hard.
They were nitriding everything on the M96 back in 2000, so they have quite a bit of experience with the process
Agree on the cleaning. Still takes forever to get the copper out.
My nitriding folks have been advising me to stay away from treating stainless barrels, specifically very hard stainless like 410 or LW. Another thing they've reported back is that some companies have used to heavy of a treatment which can cause the nitrided surfaces to shear from the substrate. Actually IIR correctly, this what Noveske experienced when they were playing around with it on stainless test barrels.
Were working up to cook one here in September. I'm actually ordering the blanks for the test today. Were going to bench a carbine and print groups at intervals as a non-scientific test. We'll also be measuring throat erosion. We're going for carbine testing this time to focus on durability versus my previous (again non-scientific) before and after accuracy tests.
