Abstract: A portion of a work-hardened essentially tubular work piece such as a metallic firearm cartridge case is annealed by contact with solid or granular tooling material which has been heated to a temperature approximately that of the appropriate annealing temperature, thereby reducing the possibility of overheating the work piece, and also thereby permitting the annealing of only that portion of the work piece contacted or in close proximity to the point(s) of contact.
