I wasn't recommending bore butter or crisco for long term storage, or trying to imply that shooting black powder in a clean dry barrel would cause severe fouling. What I'm trying to say is that a patch should follow the alcohol treatment to protect the bore from atmospheric moisture. It will serve for the short time that follows the alcohol and the shot, and won't cause the black goo. It also won't interfere with the ignition or the powder when it comes time to shoot like petroleum products.
