An endcap is coupled to the front end of the case and is adapted to retain the projectile entirely within the case. A primer is positioned along the longitudinal axis towards the base end of the case. A primer support is coupled to the base end of the case and is adapted to support the primer within the case. The cartridge assembly includes at least one obturating lip seal to seal at least one of the endcap or the primer support to the case.
