Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from a compacted mixture of metal powders that includes zinc and iron powders and which may include an anti-sparking agent. The compacted mixture is heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. A majority component of the frangible firearm projectile may be iron. One or more of zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form a minority component of the frangible firearm projectile. The anti-sparking agent may include a borate, such as boric acid.

A non-jacketed bullet including a monolithic sintered body and a sintered projectile tip. The monolithic sintered body includes a base portion and a deformed hollow nose portion, and the sintered projectile tip includes a base portion and a nose portion. A portion of the sintered projectile tip extends into the deformed hollow nose portion of the monolithic sintered body and a portion of the sintered projectile tip extends from a distal end of the deformed hollow nose portion of the monolithic sintered body. Also, a method of manufacturing a non-jacketed bullet including providing a monolithic sintered body including a base portion and a hollow peripheral portion providing a sintered projectile tip, inserting a portion of the sintered projectile tip into the hollow portion of the monolithic sintered body, and forming the hollow peripheral portion into the shape of a hollow tapered nose.

A projectile has a liner forming an interior void, and a core disposed in a first region of the void proximal to a trailing end portion of the liner, with a portion of the void disposed forward with respect to the core. An outer jacket covers a leading end portion of the liner to enclose the interior void. When the projectile impacts a target object, the core travels in a direction of flight through the leading end portion of the liner to impact the object. When the projectile impacts a target surface at a non-zero angle of approach with respect to the normal of the target surface, the projectile creates a deformation in the target surface immediately before the core travels through the leading end portion of the liner to impact the target. This deformation reduces the probability that the core will ricochet off the deformed portion of the surface.

Embodiments of a projectile are disclosed herein. According to various embodiments, a projectile includes a substantially solid core of a material, and two or more petals attached to the core. The two or more petals can be formed from the same material used to form the core and can include a trocar tip. A cavity can be bound by the core and inner surfaces of the plurality of petals.

A projectile having a projectile body that includes a front end and a rear end. A cavity in the rear end of the projectile body. An internal core in the cavity. The internal core including a front end and a rear end. The front end of the internal core inserted towards the front end of the projectile body.

The present invention relates to warheads with blast wave conditioners and in particular to devices for quickly removing a door to permit entry through the doorway. It discloses a device and method of shaping the pressure wave pattern by the use of inert material. The inert material of the present invention is used to reduce localized directional effects occurring at the point of impact, instead generating a more diffuse pressure-wave pattern across the target surface.

The invention relates to a projectile (5) with a frangible material, for short-range ammunition. To prevent any significant losses of precision and prevent the internal ballistic loading from being so great that it leads to the destruction of the projectile, it is suggested according to the invention that the projectile (5) consists of a shell (4) made of brass, the shell (4) has, seen in the direction of flight, a front cylindrical receiving space (4a) and a rear cylindrical receiving space (4b), the two receiving spaces (4a, 4b) are arranged coaxially with the longitudinal axis (15) of the projectile and are separated from each other by a partition wall (16), the partition wall (16) forms the floor (18) of the front receiving space (4a), and a core (1) of a frangible material is inserted in the front receiving space (4a), the tip (17) of the core (1) protrudes out of the front receiving space (4a), and at least one predetermined breaking point (2), running around the circumference of the shell (4), is formed in the shell (4) in the region of the partition wall (16).

An assembly (2) for attachment to a projectile comprises a first part (4) and a second part (6) mounted for rotation relative to the first part (4) about an axis (A). There is an axial gap (G) between the first and second parts (4, 6). At least one plastically deformable element (34) is arranged within the gap (G) between the first and second parts (4, 6), the plastically deformable element (34) being such as to deform due to the closing of the axial gap (G) between the first and second parts (4, 6) during launch of the projectile.

Charged projectile assemblies include a housing and an electronic assembly configured to produce an electric field about at least a portion of the housing of the projectile. Cartridge assemblies for use with firearms include charged projectiles. Methods of charging a projectile include forming an electric field about at least a portion of a projectile and extending the electric field at least partially between a forward portion of the projectile and an aft portion of the projectile.
