Abstract

A propelling cage sabot is provided with longitudinal slits and its front region is provided with centering holding elements which are oriented inwardly toward the projectile while its rear region has a centering face associated with the projectile. A rear opening in the propelling cage sabot is provided with an internal thread to accommodate a screw-in element which at its front serves as a seat for a tail surface of the projectile. Compressible band-shaped elements disposed around the circumferential region of the propelling cage sabot may be provided. Conical surfaces of the propelling cage sabot facilitate insertion of the arrangement at a cadence customary in automatic equipment, with any possibly occurring insertion shock not resulting in relative axial movement of the projectile with respect to the propelling cage sabot due to a frontal holding region and the centering surface. Under the influence of the air streaming in from the front, the parts of the propelling cage sabot formed by the above-mentioned longitudinal slits and held together in the frontal region by the band-shaped element are pivoted away from the projectile and tear apart the band-shaped element, thereby re…
