ABSTRACT:
A wedge-shaped seal for sealing against leakage of gun gases past a projele in the bore of a gun barrel includes a wedge-shaped tip having rearward angled forward and rear surfaces which is preloaded to bear the tip against the projectile body. A wedge-shaped region between the lip and the projectile body is partly collapsed by the pressure of gun gases on the rear surface of the lip to improve the seal. A similar seal may be provided with the bore of the gun barrel.
