I have a Lee 20lb Drop pot and an 8lb RCBS Iron casting pot where you would use a dipper. Obviously, only the cleanest lead is going to be put in the Lee pot. the RCBS one is small, but more versatile as a potential platform to process lead with.
Obviously I should really consider getting pure lead from someone else instead because I clearly don't have the means to process anything but a small amount of lead at a time, plus I have no experience with lead processing in the first place as well.
