Title: Dummy ammunition round method and apparatus

Abstract: The present invention is for a method of making a dummy ammunition round for a firearm which includes the steps of selecting a new or used metal casing of a used cartridge having a base end and an open end and then cutting an aperture in the base of the selected new or used metal casing. A polymer insert member is then formed having two end portions and shaped to fit into the selected metal casing with one end of the insert member having a protrusion sized to fit into the aperture cut through the casing base and the other end portion having a generally bullet shape for protruding from the open end of the metal casing. The formed polymer insert is then press fitted into the selected metal casing by press fitting the protrusion on one end into the aperture in the base of the metal casing and a portion between the ends being press fitted into the open end of the metal casing so that the bullet shaped end protrudes from the casing to thereby form a dummy bullet for practicing the clearing of malfunctions from semiautomatic and automatic firearms. The process can also include the steps of removing a used firing cap from the base of the selected metal casing by the drilling of the aperture into the casing. The polymer member can be formed by molding an ABS or other polymer into the predetermined shape. The polymer insert member has a ledge formed on one end portion adjacent the end portion protrusion to limit the insertion of the polymer insert member into the casing.
