Abstract
A handloader tool for use in the fabrication of cartridge shells. The tool accomplishes uniform flash hole sizing. The tool includes a depth gage section which results in a cutting tool being inserted to a constant uniform depth into the cartridge flash hole. The cutting tool has an angled upper portion to provide a uniform chamfer of, for example, 60 degrees at the flash hole exit area. The overall tool assembly further includes a slidable centering cone to provide means wherein the cutting tool is always inserted at a desired straight angle into the flash hole area. The invention further includes a method of flash hole uniforming using the described handloader tool.
