Abstract
A high-pressure self-sealing obturator positioned to fit on the rear of a bot assembly in a discarding projectile assembly to prevent the obturator from backing off during initial impact of bore walls by the projectile assembly. The obturator includes an extension and a groove for snapping a case mouth into the extension. The outer surface of the obturator conforms with the bore of the gun. The extention of the obturator also includes a 'V' groove which permits the separation of the extention with the case mouth during the initial low pressure which occurs early ignition. The self-sealing obturator provides efficient and improved obturation for a projectile when fired from a high pressure gun tube.
