I'm not sure how much good it did on this nitrided barrel.
I guess the next time I shoot this we'll see if a little more shooting caused it to improve.
I have a fairly high end nitrided barrel I installed recently as well, but it doesn't have many rounds down it either...................cleans up pretty well but I polished & cleaned it thoroughly before ever firing it. I've only shot it with a 6x scope & it's been just a hair over MOA; I'll eventually put a scope with more mag on it as well & see what happens as it's shot more.
I think the jury is still out on how nitrided barrels either do or don't change over time.
But I can say that Compass Lake Engineering, who are about as reputable as it gets in the field, & who install both Bartlein & Kreiger barrels, told me that they do not nitride any barrels because that prevents them from ever fully "breaking-in".
