Abstract From the Canadian patent
A plastic cased metal headed ammunition casing for high powered rifle cartridges is described in which the plastic case has a pressure regulating baffle or wall in the forward end thereof to regulate and control the development of chamber pressure movement of the bullet into the rifle barrel. The cartridge is charged with a given charge of powder and the cap or head securely fastened to the rearward portion of the plastic casing. The head provides sufficient resistance to the residual pressure after firing so that the cartridge can be used in rapid fire automatic weapons.
