Abstract
A device for machining a cartridge case that has a neck comprising a circular neck wall, a mouth and a primer pocket. The device includes a gripping assembly, adapted to accept and retain a cartridge case and a neck machining assembly, positioned to engage the cartridge case from a first direction and adapted to machine the neck of the cartridge case. Additionally, a primer pocket machining assembly is positioned to engage the cartridge case from a second direction, opposed to the first direction, thereby permitting simultaneous primer pocket and neck engagement, and adapted to machine the primer pocket.
