Abstract

A device for reshaping casings of spent ammunition cartridges, in one embodiment reduces the diametrical size of the casing wall by forcing the casing into an annular space at the end of a housing through which a plunger shaft slides. In another embodiment, the mouth of a casing is flared outwardly by engagement with the exterior of the end of a housing which has a circumscribing groove to enable easier disengagement of the re-shaped casing. The preferred reshaping devices comprise a plunger having shaft which, when contacted by a casing being re-shaped, compresses an elastomer spring that substantially fills a spring housing cavity and has an exceptionally high spring rate. After each reshaping, the spring causes the plunger shaft to disengage the casing from the device. A recess in the terminal end of a plunger shaft avoids damaging new types of unique two piece casings that have a wave at the interior bottom of the casing.
