A tool for removing detonated Berdan primers from fired cartridge cases has a sleeve to support an undetonated primer at one end immediately adjacent the inside surface of the closed end of the cartridge against which the end of the sleeve fits snugly. A firing pin longitudinally movable within the sleeve and extending from the other end explodes the primer when tapped sharply, and the explosive force through the small flash holes in the closed end of the case ejects the spent primer from the case. The sleeve is cylindrical an is just slightly smaller than the open end of the case. It has a cylindrical pocket at the end that accepts either a Berdan, Boxer, or other type of primer and has a longitudinal bore that is smaller than the diameter of such primer and guides the end of the firing pin. At the other end of the sleeve is a handle of larger diameter than the sleeve and preferably provided with a reentrant recess.

A decapping tool for removAl of a spent primer from a cartridge case by means of an explosive charge, the cartridge case comprising a tubular member with an open end and a closed end, the latter end having a primer recess extending into its outer surface and flash hole means through the closed end from the recess to the interior of the cartridge case, the tool comprising: A. a cylindrical sleeve for insertion into the inside of a cartridge case, said sleeve comprising: 1. a section having an external diameter slightly smaller than the open end of the cartridge case. 2. a squared-off end adapted to fit snugly against the inter surface of the closed end of the cartridge case around the flash hole means, 3. a cylindrical cavity extending axially into said squared-off end to receive an ejection primer and hold it immediately adjacent the inner surface of the closed end of the cartridge case, and 4. a longitudinal bore from the cavity to the other end of the sleeve; B. a handle attached to said sleeve remote from said squared-off end to permit said squared-off end to be held firmly against the inner surface of the closed end; and C. a firing pin slidably positioned in the bore, the length of the firing pin being greater than the length of the sleeve from the cavity to the other end thereof, one end of said pin extending beyond the other end of the sleeve for application of mechanical firing force to said one end of said firing pin to drive the other end of said firing pin against said ejection primer to explode the ejection primer.
