ABSTRACT:
An ammunition cartridge includes: a basewad disposed within a tube proximate the aft end of the tube; a projectile wad disposed within the tube proximate a fore end of the tube; a propellant charge disposed within a chamber formed between the projectile wad and the basewad; and a projectile disposed within the tube between a forward facing surface of the projectile wad and the fore end of the tube. The aft end of the projectile wad has a powder cup skirt formed thereon, and a chamfer is formed around an outer perimeter of a lip of the powder cup skirt. The chamfer allows the powder cup skirt to be slidably received within a skirt of the basewad to form the chamber. The chamfer provides a clearance at the powder cup skirt lip, which helps to insure undisturbed entry into the mouth of the basewad skirt.
