ABSTRACT:
A cartridge is disclosed for use in a ballistic weapon system. The cartridge includes a tubular case and a ballistic projectile. The projectile has an annular groove which extends into an exterior periphery of the projectile. The tubular case has a cylindrical sidewall and a substantially closed rearward end. The cylindrical sidewall defines an interior cavity for receiving at least a rearward portion of the projectile. An annular lug is integrally formed with the cylindrical sidewall and inwardly extends from the sidewall into the annular groove of the projectile, interlocking the projectile and the tubular case. Longitudinal slits are formed in the forward end of the tubular case to allow the case to expand for receipt of the projectile until the annular lug is aligned with and then inserted into the annular groove of the projectile. After the cartridge is fired, the annular lug restrains the projectile within the tubular cartridge case until combustion of the charge causes a rapid pressure buildup to exceed a predetermined pressure, which causes the predetermined shear strength of the annular lug to be exceeded. The annular lug then shears and the projectile moves forward from within the tubular case.
