Bullets, including lead-free bullets, and associated methods
First Claim
1. A bullet comprising:
- a jacket defining a cavity having a closed end and an open end;
a core positioned within the cavity and extending from the closed end to a first intermediate portion of the cavity, the core including a plurality of particles, the particles having outer surfaces and a dimension of from about 0.003 inches to about 0.038 inches;
a seal positioned within the cavity and extending from the first intermediate portion of the cavity to a second intermediate portion of the cavity, wherein the second intermediate portion of the cavity is spaced apart from the open end of the cavity; and
a material positioned on at least portions of the outer surfaces of the particles, wherein the material is configured to lubricate the particles during compaction within the cavity and to facilitate separation of the particles after an impact.

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.

26. A bullet comprising:
-
a lead-free jacket having a tail section with a base, an intermediate section extending from the tail section, a nose section having an ogived outer surface extending from the intermediate section to a terminus, an opening at the terminus, and an inner surface defining a cavity extending from the opening to the base; a lead-free core positioned within the cavity, the lead-free core extending from the base to an intermediate portion of the cavity, and the lead-free core including— a plurality of compacted metal granules having outer surfaces, the metal granules, prior to compaction, having a dimension of from about 0.003 inches to about 0.038 inches; and a layer on at least portions of the outer surfaces of the metal granules, the layer configured to lubricate the granules during compaction within the cavity and to facilitate separation of the granules after an impact; and a seal positioned adjacent the lead-free core, wherein the seal is spaced apart from the opening at the terminus. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A bullet comprising:
-
a body including— a core having a plurality of metal particles; a jacket having an opening and a surface at least partially defining a cavity; and
,a material in contact with the metal particles, the material configured to lubricate the metal particles during compaction within the jacket and to facilitate separation of the particles after an impact; and sealing material positioned on at least a portion of the surface and on at least a portion of the core, wherein— the sealing material has a solid state, the sealing material previously had a non-solid state, the sealing material on the core is spaced apart from the opening, and the sealing material prevents foreign matter that enters the cavity through the opening from contacting the portion of the surface and the portion of the core. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56)
