A caseless ammunition cartridge includes a unitary outer portion having forward, central section and rear sections. The forward section has an aerodynamic tangent ogive profile. The rear section has a cylindrical profile. The central section has a conical profile that transitions from the radius of the forward section to the radius of the rear section. An inner core, disposed within the unitary metallic outer portion, has a front portion encased by the forward section of the unitary outer portion, and a cylindrical rear portion disposed within the central and rear sections of the unitary outer portion. An annular cavity is disposed between the unitary outer portion and the rear portion of the inner core. A propellant is disposed within the annular cavity. A combustible seal covers the annular cavity to protect the propellant.

A mechanism for extraction caseless ammunition, the mechanism for extraction including a receiver (84) interacting with the lid of the receiver (85); lock frame (86) which interacts with the lid of the receiver; bolt (88) made in the lock frame; a conical bushing (93) installed inside the bolt through the firing pin (89); an extractor (95), wherein lock frame is made with a front ledge (87); on the front end of the firing pin the conical part (90) is made; conical bushing (93) is made with interior ledges (94); a shaft (103) with a circular groove (104); the rear part (102) passes into the lower ledge (106) which has a front inclined area (107) and a rear horizontal area (108) and the lower ledge (106) passes into the upper ledge (109) which has a front inclined area (110), an upper horizontal area (111) and a rear inclined area (112).

There is disclosed caseless ammunition, composing a shell, a propellant placed in a shell chamber, and an igniter block. The body of the shell is made with a cylindrical part, which passes into a inclined surface of the leading cylindrical part, which goes into the rear cylindrical part, wherein: the inclined surface is made at an angle to the longitudinal axis of the shell body; the leading cylindrical part is made with a wall thickness; of the leading cylindrical part is 0.122D, where D is the outer diameter of the ammunition; the rear cylindrical part is made with a smaller diameter than the diameter of the leading cylindrical part; a ledge formed between the leading cylindrical part and the rear cylindrical part; the rear cylindrical part ends with a chamfer; an inlet interior cylindrical hole made in the body of the shell, into which an ignition block is installed.

An axisymmetric disk-shaped cartridge is provided for firing from a gun having a fluted bore. The cartridge is initiated by a firing pin and includes a primer core, a propellant charge, a booster charge, a projectile mass, an ablative cap and a ductile metal coating. The projectile mass is disposed over the booster charge while the ablative cap is disposed over the projectile mass. The coating and mass elongate and radially narrow to maintain axial symmetry while being accelerated along the bore.

A caseless cartridge with a projectile, a propellant, and an ignition source. The ignition source is configured to ignite the propellant in response to an activation of the firearm. The propellant is molded around the projectile and is configured to propel the projectile from the firearm upon ignition. When the firearm is activated, the propellant is consumed, and the projectile and the ignition source are discharged from the firearm. The projectile has a bullet, an ignition housing, and a shaft. The bullet is positioned on a leading end of the projectile, while the ignition housing is positioned on a trailing end opposite the leading end. The shaft extends between the projectile and the ignition housing. The projectile may also have a plurality of fins to stabilize the projectile during flight and a plurality of ignition ports. The ignition source may ignite the propellant through the plurality of ignition ports.

A muzzle loaded ammunition round having a bullet and a consumable cartridge case. The cartridge case is hollow and is filled with at least one propellant composition, the cartridge case being constructed from a consumable material, such as foamed celluloid. The bullet is commonly engaged to the propellant composition at least via the cartridge case, the propellant composition having a charge weight.

A caseless cartridge including a projectile. A bullet is positioned on a leading end of the projectile and sized to exit a firearm through a barrel of the firearm. An ignition housing is positioned on a trailing end of the projectile opposite the leading end. An ignition source is positioned within the ignition housing. A hollow shaft extends between the bullet and the ignition housing and joins the bullet to the ignition housing. A plurality of ignition ports extend through a wall of the shaft and through the ignition housing. An interior of the shaft is fluidly coupled to an interior of the ignition housing. The ignition source is configured to ignite a propellant through the plurality of ignition ports in response to an activation of the firearm. When the firearm is activated, each component of the caseless cartridge is either consumed or discharged from the firearm through the barrel.
