I cleaned my 58 cal. rifle and got some patches that had black streaks where the patch came into contact with the grooves. Shows up very dark (blackish gray) on a patch as I start to dry the barrel.As I progress to additional dry patches, it becomes less noticeable. They are not brownish in color, so I don't think it is rust. Thinking it might be lead build up in the barrel. Think the previous owner shot only conicals. Barrel is otherwise smooth as glass.
What is good to help in getting the lead from the barrel?
