[QUOTE="Mikecr, post: 974786, member: 1521"] You can shoot good as long as possible between cleanings(camp B). Or, you can shoot good as long as possible between barrels(camp A). When carbon remains for many shots it gets hammered in. This is referred to as 'hard carbon'. It's fine for a while, fitting in nicely with all the other fouling present, and the gun still shoots good -until it doesn't. An abstract constriction eventually affects results like a switch, reaching a point of too much copper at least. Camp B goes after it then, cleaning away the loose fouling, but the hard carbon has taken hold. It isn't going anywhere so easy. This is ok for a while, as camp B can re-foul with ~10-15 shots and with that performance comes back for another stretch. This manifests inconsistently between guns due to bullet to bore fit, which varies lots to lots with components. So camp B really needs camp B bullet/bore combinations to be successful in the long run of it. But eventually, and this happens with every barrel if nothing else takes it out first, a hard carbon constriction switch flips. This is the point where the hard carbon has to be removed before the barrel will shoot well again, and often, by that point, removing it is too damaging to recover. It even happens with better cleaned bores, as the carbon impinges into the lake bed cracking, lifting the surface to constriction, and then you can have panels of the lake bed braking away with shots,, or not(bad either way). Those who really like their barrels enough to get them setback, only recover ~1/2 the life again, and then ~1/2 of this on another setback, and then it's done. That's when a barrel is declared dead. It's carbon cancer. Much of this is synonymous with the lecturing we get from our dentists.. You can go through all the efforts to keep your teeth clean, or less efforts while accepting that repairs will have to be made before long, and eventually loss of bone in the gums will run away with it. Some would argue that constant cleaning would expose teeth to the elements killing them anyway. But when the day comes that dentures are the only viable solution, we'll wonder more about it.. Camp A, or Camp B? I'm Camp A. I know that my barrels will eventually die no matter what I do. But I'm doing my best to ensure it doesn't happen before it should. I don't allow hard carbon to build on the bore surface. That much I can control. Someday we'll all melonite our barrels, hopefully eliminating carbon impinging. Maybe, with constant management of surface carbon, these barrels will last beyond further concern. Camp A will benefit here, not so much for camp B. [/QUOTE]
