Abstract: 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.

Abstract: There is disclosed a kinetic energy type projectile having an armor piercing head which is intended to penetrate multi-shell targets, and even sharply angled targets. The piercing head is provided with favorably discriminated shearing regions which are axially spaced apart by distances corresponding to the thicknesses of the shells which are to be pierced by the piercing head. The shearing regions are provided by external or internal localized transverse weakenings e.g. grooves, or heat treatments by electronic bombardment, applied to the external surface of the piercing head and/or in a central bore in the piercing head. Additionally, the localized weakenings may be provided by bound collars on the piercing head.The shearing regions are progressively stronger in a direction from the front of the piercing head so that they will shear consecutively as the head pierces successive shells of a multi-shell target.

Abstract: An improved explosive and incendiary full caliber projectile having a high splinter effect. The projectile produces a reliable incendiary effect at impact by releasing splinters from the casing. It is of simple construction and the casing and splinters have a high penetration capability in particular when the projectile is less than 40 mm in caliber.At least a preponderantly longitudinal portion of the casing is made of a homogeneous substance consisting of a heavy metal alloy having a density in excess of 17 g/cm.sup.3. By using a sintered high tungsten content casing a relatively larger volume of an explosive charge can be used which enhances the penetration capability and splinter swarm producing effect of the projectile at impact.
