A friend that has more Ruger SA's than I, and most OM's, has told me she has a 75lb wad of lead scrounged from a re-do of a doctors office.. She, a nurse, assures me it's safe. Um, not sure, zombie bullets ? I may have to get a 480 mold of some kind now. Have cast .54 minie type bullets and rounds balls, many yrs ago. Thoughts ?
