I normally buy lead bullets to reload for my guns. I just got the dies to start reloading my wife's 9mm, and bought copper plated bullets for her gun. A guy as work that use to reload is telling me that the fouling from the copper plated bullets is much worse than lead and I should just use lead. I do know the Choir Boy's clean the leading out pretty well and is easy to do. Copper fouling is a new one on me. For those with more experience than I have what are your thoughts.
