I have seen $700 bolt barrels that were rougher. I put it in a low end Aero receiver, it was a very tight fit so I left it unbedded, with a Aero BCG , Seekins handguard, Midway std gas block. Did the break in today and was extremely impressed. I used a bunch of old steel cased Wolf for the break in. Shot 1 cleaned for first 5 rounds, then shot 3 rounds and cleaned two times, then moved up to 5 round groups and copper was minimal when cleaned after the first. I have broke in Criterion, Shilen and Kreiger barrels on bolt rifles that gave me more problems with copper and carbon. The last 5 round group was about 1 MOA using trash ammo. next week I will do some serious load development. I would bet a 6 pack of adult beverage I can get sub MOA at 850 yds with some 8208 and decent bullets in some handloads.
It better have been min copper to remove since you was fireing a copper washed steel jacket bullet lol.
