Abstract
A bullet (50; 100) includes at least a mid core (52) and a rear core (56) in tandem alignment. The hardness of the mid core (52) is greater than the hardness of the rear core (56). A jacket (16) envelops both the mid core (52) and the rear core (56). The jacket (16) has a generally cylindrical sidewall (62), which is in contact with the mid core (52), and a boat-tail (22), which is in contact with the rear core (56). The rear core (56) is substantially container within the boat-tail (22). The mid core (52) and the rear core (56) may be substantially lead-free. In one embodiment, the bullet (50) includes a front core (12) in tandem alignment with the rear core (56) and in contact with a nose portion (18) of the jacket (16). In another embodiment, the mid core (52) extends from the noise portion (28) of the bullet (100) to the boat-tail (22).

An ammunition cartridge (50) includes: a basewad (52) disposed within a tube (51) proximate the aft end (56) of the tube (51); a projectile wad (92) disposed within the tube (51) proximate a fore end (59) of the tube (51); a propellant charge (96) disposed within a chamber (94) formed between the projectile wad (92) and the basewad (52); and a projectile (100) disposed within the tube (51) between a forward facing surface (101) of the projectile wad (92) and the fore end (59) of the tube (51). The aft end of the projectile wad (92) has a powder cup skirt (77) formed thereon, and a chamfer (81) is formed around an outer perimeter of a lip (57) of the powder cup skirt (77). The chamfer (81) allows the powder cup skirt (77) to be slidably received within a skirt (80) of the basewad (52) to form the chamber (94). The chamfer (81) provides a clearance at the powder cup skirt lip (57), which helps to insure undisturbed entry into the mouth of the basewad skirt (80).
