Abstract
A projectile to be fired from a gun having a chamber (2) with a conical transition region (4) to a caliber barrel (3) that adjoins the front of the gun. The projectile (5) has a sub-caliber penetrator (6), a jettisonable propelling cage sabot (7) connected to the penetrator (6), and at least one guide band (10) adapted to the caliber barrel (3) secured to the rear side or portion of the sabot. To ensure that the rear region of the propelling cage sabot (7) seals the chamber (2) against propellant gases that are pushing forward, even if the guide band (10) itself is still located in the chamber, an additional sealing ring (14; 17), comprising a deformable plastic, is provided on the existing guide band (10) adapted to the caliber of the barrel (3). The sealing ring assumes the function of providing the initial seal after the cartridge is ignited.
