In my experience, JB Paste is good for getting the barrel clean, but it's not going to fix crappy machine work. It may help with extremely fine imperfections from the rifling cutting process, but maybe no more than simply shooting it. A real lapping, in which a lead lap is cast to the bore and then used with a lapping or polishing compound is different, and can definitely improve (or ruin) a barrel, depending on the skill of the person doing it. For most of us, if we have a barrel that doesn't shoot, or, doesn't shoot long due to extreme fouling, then it may have problems that can't be fixed by just aggressive cleaning methods. I've had two barrels replaced under warranty during the last year. They were both LW barrels with poor machine work.
