| I would guess that it's a combination of powder fouling and tarnished copper. Does it come out when you clean it? If you scrub it with a powder solvent do you see green or copper fouling in the bore. |

| A lot of the older rifles fired ammunition loaded with cordite (at least the english ones). Cordite burned very hot and caused the barrels to become black, also called cordite burn! I have seen many rifles in this condition. |

| Some ex-mil ammunition (if that's what your using) has a tar like sealer on the projectiles that can leave some pretty stubborn black fouling. Cheers... Con |
