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.

A spin stabilized carrier projectile to be fired from a rifled gun barrel of a given caliber, said projectile comprising: a thin-walled shell having a wall thickness equal to or less than 0.05 times the caliber of the gun barrel; a projectile base connected to a rear end of said shell and partially overlapped by said rear end of said shell so that said base radially supports said shell in the overlapped region; a metal driving band disposed on outer surfaces of said base and of said shell in said overlapped region; and, a plastic ram ring disposed on said outer surface of said shell in front of said metal driving band in a region of said projectile shell which is not supported by said projectile base.
