Abstract
Bullets, including lead-free bullets with frangible cores, are described herein. In some embodiments, a bullet includes a jacket having an inner surface defining a cavity having an open end and a closed end. The bullet also includes a lead-free core positioned within the cavity and extending from the closed end to a first intermediate portion of the cavity. The core includes a plurality of particles that are compacted within the cavity to form the core. The bullet also includes a seal positioned within the cavity and extending from the first intermediate portion to a second intermediate portion of the cavity. The seal abuts the inner surface of the jacket, thereby substantially sealing off the core within the cavity. The bullet may also include a polymeric tip having a forward portion projecting forward from the open end and a rearward portion extending rearward into the cavity.
