Chamber Nested Bolt and Oval Rifling

Abstract

A means of keeping the cartridge in the chamber during the firing sequence until the peak pressure drops to a safe level by nesting the bolt into the chamber with the cartridge. The bolt and cartridge will form a gas seal and recoil backwards when the gun is fired, but the chamber walls will support the cartridge while it recoils backwards until it exits. The gun will be designed so that it does not exit until the pressure drops to a level where the cartridge can withstand the force. Doing this will allow the gun to utilize high pressure ammunition without requiring complicated locking and/or delay mechanisms currently used. This will decrease the initial cost of manufacturing the gun, improve accuracy and reliability, and reduce the peak recoil felt from the gun. Also spinning a projectile by using an oval cross section where the major and minor axis rotates around the center of the oval eliminates the need for groves and polygonal rifling. This will increase the efficiency and the precision of the gun.
