I have a cast iron pot that holds about #15 of lead and that sits on a hot plate to heat up lead for the only LEE pot I have, the baby #10 production pot. I don't know why I don't get a #20 pot since I go through a lot of lead in one sitting but the #10 pot works for my needs and I just top it off with the cast iron pot when I need more lead. Kinda used to the work flow now.
