  • Patent number: 11940254
    Abstract: A projectile designed to be lead-free and have a ballistic coefficient ranging from about 0.13 to about 0.80 or greater for enhanced energy/performance at extended ranges may have an elongated body formed with a jacket including a wall having an end defining an ogive portion and a cavity or recess defined within the jacket and in which a core is received. The projectile can be configured in various calibers and sizes. The projectile core may be formed from a plurality of core sections, and at least one of the plurality of core sections may include tungsten powder and a lead-free binder material pressed together to form a substantially cylindrical shape or compact. One or more of the core sections further can be sintered, and the one or more core sections may be received in an end-to-end relationship within the cavity defined by the jacket to form a stacked, sectional core.
