Abstract
A medium caliber polymer-based ammunition cartridge has an insert forming a base end and engaged to a polymer body forming an internal propellant chamber. The polymer body is engaged at its forward end to a polymer nose which has a shoulder that transitions directly into a projectile opening. The shoulder is inwardly radially thickened to increase lateral support about a medium caliber projectile loaded into the cartridge. The thickness of the shoulder may vary along its longitudinal length. One or more crush seals may be integrally formed about an outer surface of the cartridge nose. The crush seals include an annular tip seal and one or more annular shoulder seals. Each of the crush seals deform into an obturating ring to form a seal between the outer surface of the medium caliber polymer cartridge and the inner walls of the firing chamber.
