[QUOTE="MagnumManiac, post: 2550038, member: 10755"] Even an unfired barrel will have black patches come out with JB, it cuts even the slightest left over crud/oil from when being cut/broached. I find CLR and Brake clean or throttle body/carb cleaner to work best on heavy carbon fouling. There is also the possibility that the black is residual oxide from the cutting of the rifling left behind after the barrel was lapped. Sitting around in a rack can cause oxidation of some lapping compounds. Cheers. [/QUOTE]
