50% Wheel Weights an 50% roofers sheet lead, bullets are air cooled out of the mold and allowed to air cooled after powder coating. I actually use the same alloy in my HV 30-06 loads with the exception that I water quench the bullets after powder coating right from the toaster and allow a couple weeks for the bullets to age harden. I shot bullets cast from the 50/50 alloy powder coated and gas checked up to 2300 fps. in my old Rem. 770 with excellent accuracy.
