ABSTRACT:
An improved cartridge case flash hole uniformer having a hardened self-cleaning reaming and chamfering blade for use either as a hand tool or with a power drive for providing the consistent case to case uniforming of flash holes to facilitate the communication of a uniform bloom of detonating primer flash from the primer pocket by way of the flash hole into the cartridge case power chamber in turn for consistently generating uniform propellant charge ignition, and thereby enhance the cartridge factor accuracy of reloaded ammunition from round to round for match and precision bench rest shooting applications.
