Top takeaways

  1. CERROSAFE alloy shrinks initially then expands to exact chamber size after an hour, and further expands by .0025" after 200 hours, which is considered by toolmakers.
  2. The alloy melts at 158° - 190° F and should be melted in a clean iron ladle, poured once fully melted, and removed from the chamber when it cools to room temperature.
  3. Before casting, the rifle chamber must be clean and the bore plugged near the throat; the alloy should be poured through a tube and the barrel warmed if cold.
