A subcaliber projectile including a segmented discardable propelling cage sabot which encloses at least a portion of the projectile body and has a common form-locking zone for the transfer of acceleration forces from the propelling cage to the projectile body. The form-locking zone has mating annular grooves and counter grooves on the exterior surface of the projectile body and on the interior surface of the propelling cage, and is subdivided into several form-locking zone regions in which the annular grooves have a different groove spacing that is adapted to the locally occurring shear stresses. These measures enhance simplification of the manufacturing process and result in an improvement of the release of the propelling cage sabot from the projectile body and in an increase in the target impact velocity of the projectile body.

A spin stabilized projectile unit includes a sub-caliber projectile having a cylindrical section connected to a conical tail section including an external circumferential holding groove. A propelling cage casing encloses the projectile. A propelling base includes a receptacle holding the projectile and connected with the projectile and the propelling cage casing. The receptacle includes inwardly projecting axial webs presenting an inner diameter of the receptacle in a region of the cylindrical section of the projectile which corresponds to the outer diameter of the cylindrical section. The inner diameter of the receptacle formed by the webs becomes increasingly larger than the respective outer diameter of the conical section beginning in the transition region between the cylindrical and conical sections to form an annular gap extending to a bottom region of the bottom of the receptacle. A segmented holding ring is disposed between the inner diameter of the receptacle and the outer diameter of the conical tail section and lies in the holding groove and against the inner diameter of the receptacle for holding the projectile in the receptacle of the propelling base.

Spin stabilized projectile unit

A training cartridge including a training charge contained in a cartridge case. The training cartridge is for use in externally driven automatic weapons firing at high cadences and is to be manufactured easily and economically. This is accomplished by a cylindrical plastic insert having a central bore which accommodates the practice charge. It is introduced into a central case and is fixed therein by means of an externally applied rolled section.
