I have a new mold from BABore that he suggests I cast pure lead at 725-750 degrees. This is the first time I've used pure lead for something other than lap boolits.
When I run my RCBS wide open with wheel weights it will get 825 or so. Wide open with pure lead and it stays in the 725-750 range. This is not a problem, in fact it is what I want.
SO, does it take more heat to heat lead to the same tempeture as WWs?
Inquiring minds want to know.
