A fragmenting bullet has a metal core having a generally cylindrical rear section and a tapering forward section, a plurality of spaced slots in the forward section forming a plurality of prongs. A metal jacket encloses and substantially conforms to the core. The jacket has an open forward end, and a plurality of lines of weakness in the portion of the jacket over the forward section of the core.

The present invention provides a metal injection molded ammunition cartridge comprising a metal injection molded bottom portion comprising a primer recess in communication with a primer flash hole that extends into a propellant chamber and a metal injection molded body extending form the metal injection molded bottom portion.

An expanding bullet having a one-piece structure has a cylindrical section and a section that is essentially shaped as a truncated cone, with the bullet tip being situated at the end of the latter section, which end faces away from the cylindrical section, and at least one planned breaking point being formed in this section, wherein the section shaped as a truncated cone is divided into segments and has a channel that has a mouth in the region of the bullet tip, wherein the channel has a bell-shaped widened region, which has its greatest diameter in the region of the transition from the cylindrical section to the section shaped as a truncated cone.

A bullet with a blunt meplat with reduced drag coefficient relative to a non-blunt meplat with improved speed consistency during flight shot to shot.

A bullet (100), having: a main body (102) with a bore (106) bounded by a sidewall (124); an insert (104) that is disposed in the bore and that has longitudinal splines (460) configured to form a longitudinal flute (4620 in the insert and to provide radial support for the sidewall of the bore. A leading end (466) of the flute is open.

Devices and methods for an 8 mm semiautomatic handgun cartridge providing a reduced form factor for carrying a greater number of rounds in a smaller space while maintaining ballistic performance.

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.
