Otis pull through cable. Its one piece. Pull it through the bore and done. No dirty rod banging the bore when pulling it back through the barrel. Add a good foam bore cleaner (no brush needed) and you will never have metal touching your bore again. The cable is coated so you don't need a bore guide either.
I am working on a way to cover the brass parts of the cable so it doesn't touch the bore either but I think thats overboard as I can't see just the touching for the brass end as you thread the end through the bore does any damage but I am going to be covering it just to be anal.
