Cartridge case induction annealing apparatus

A system for induction annealing at least a neck of a cartridge case, the system comprising:

• a magnetic core having a first end and a second end separated by an air gap;
• an induction coil wound around the magnetic core and configured to generate a magnetic field in the magnetic core and the air gap;
• a cartridge case holder for holding the cartridge case such that at least the neck of the cartridge case is positioned in the air gap;
• a power supply controller operable to connect an electric power source to the induction coil to supply power to the induction coil at a selected power level for a predetermined length of time, the selected power level being selected from a plurality of power levels which are able to be supplied by the electric power source to the induction coil;
• and
• a housing,
• wherein the magnetic core, induction coil, cartridge case holder, and power supply controller are at least partly accommodated in the housing, and
• wherein the cartridge case holder comprises a hole in the housing through which the cartridge case is able to be at least partly inserted.
