Chamber Cast - To pour a low-melting-point material such as "Cerrosafe" into the chamber of a firearm, let it just cool, knock out the plug and measure it with a micrometer against published dimensional specifications to determine the correct chambering of a possibly-unmarked or possibly-altered firearm.
