摘要： An ammunition cartridge (50) has a tube (51) extending along a central longitudinal axis from an aft end to a fore end. A metallic head (53) has a sleeve portion (61) secured to the tube along an aft section of the tube and has a centrally-apertured web portion (66) spanning the sleeve portion to form a base of the cartridge. A basewad (52) contained within the tube separately formed therefrom is located proximate the aft end of the tube. The basewad (52) has a generally cylindrical exterior surface. The basewad interior surface (72) extends from a generally forward-facing inner portion, forward and outward to a generally inward-facing fore portion (76) to define a skirt portion of the basewad. At least one projectile is carried within a fore volume of the tube. A propellant charge (96) is located aft of the projectile. Wadding (92) is located between the propellant charge (96) and the projectile. The wadding (92) includes an aft portion located at least partially concentrically within the basewad skirt portion to define a powder chamber (94) containing the propellant charge (96).
