  • Patent number: 7819065
    Abstract: The cartridge-type training round consists of a projectile and a cartridge shell into which the projectile is inserted. The projectile includes a one-piece cylindrical central body (2) and a one-piece basin-shaped projectile tip (5) that is pressed onto the central body and engages a circumferential engagement bead (7) with a circumferential engagement slot (8) located in the central body (2). The cartridge shell (20) is a one-piece basin-shaped part; it is also pressed onto the central body (2) and engages a circumferential engagement bead (22) with a circumferential engagement slot (23) of the central body (2). A receiver recess (25) is provided in an approximately cylindrical projection (24) that is inserted centered from the base to receive the propulsive charge (28) and its igniter (29). The round is of simple design, and may be manufactured inexpensively owing to its simple parts that may be largely of plastic without loss of function.
