Without trying to remember all the usual suspects off the top of my head, I woul type something like "cast lead bullets" and do a Google search. There are dozens of commercial casters out there. Check their sites, and as you find ones that have what you are looking for, call em. Most have toll free numbers. When you find one with what you are loking for in stock, order it right then and there. Reloading components are still out there, you just have to look a little harder for em.
