i know it melts a little over three times hotter than lead, and its harder. but its still a soft metal. so what changes might be needed or what might you have to do to try and cast solid copper bullets instead of lead? i imagine you dont want to use alluminum molds so you would have to use steel or cast iron. and for the same size cavities used in lead the copper bullets would weigh less.
