I finally was able to collect everything I need to reload shotgun shells, with the purpose mainly for casting slugs. My plan is to buy 5lb lead cakes from a plumbing supply store and I believe they are at least 99.7% pure lead. My question is, if I am just shooting slugs at the range, do I need to mix the lead with other metals, and if I were to cast slugs for hunting, what ratio would you use?
