Abstract

To provide a complete seal in the region of the rifling, particularly in worn-out gun barrels firing spin stabilized carrier projectiles provided with a metal guide or driving band and a thin-walled projectile connected to a projectile base and having a wall thickness less than or equal to 0.05 times the caliber of the gun barrel and to reduce the ramming deceleration and the radial pressure stresses on the projectile shell during passage through the gun barrel, a plastic ram ring is disposed on the outer surface of the projectile shell in front of the metal guide band and in a region of the shell that is not supported radially by the projectile base.
