[QUOTE="yorke-1, post: 1151906, member: 11960"] I have 2 barrels that were treated when I ordered them from Benchmark Barrels. Benchmark cut the barrels, lapped them, sent them off to get nitrided, then lapped them again to clean out the residue left behind by the nitriding process. There was no break in before the treatment. The 6mm BR barrel was treated to recover a little bit of the velocity lost by going with the short 19" barrel. It has about 2000 rounds through it so far and shoots as well as it did on day one.

The barrel lasted almost 1500 rounds before the throat was so rough that I started getting erratic pressures.
