摘要： A sabot having an extended casing for containing propellant charge and a slotted top portion for securing a projectile. The propellant charge is ignited by gases that enter the lower portion of the sabot from a puncture developed by the mating of the sabot against a breech plug. The breech plug has a piercing component in the form of a sharpened forward edge to initiate puncture of the breech end of the sabot.

摘要： A dispense for dispensing an adhesive onto a remote surface, such as a case mouth and primer ammunition. The dispense includes a reservoir containing an adhesive; a positive displacement pump; and a nozzle having a tapered tip. The positive displacement pump delivers a predetermined amount of the adhesive, preferably an anaerobic adhesive, from the reservoir to the nozzle at predetermined intervals. The nozzle discharges the predetermined amount of adhesive through the air and at least 1/16-inch onto the remote surface.

摘要： The invention relates to ammunition for firearms, as smooth and a rifled barrel. The projectile with rigid attached to the housing stabilizing fletching block, plates of fletching block have a continuation on the housing, centering the projectile in the barrel. In the offered variant, on the friction and heat of the bullet and the barrel takes about 1% of the shot energy, besides low vibration. The rest of energy escapes to destination, and that's good. Erasing minimal of the barrel. Application of the projectile in the shotgun and rifle barrels increases the service life of barrels. Use of such projectiles increases the initial speed, and with the sleeve-nozzle and a second charge, allows to increase the speed and specialization of the projectile. At the expense of the aerodynamic and gyroscopic effects, increases the lethal effect over long distances, due to the greater energy saved, improve the close grouping of shots and flat trajectory.

摘要： The invention relates to a cartridge having a projectile, and a case which is mounted on the projectile from behind and which has a case mouth at the front end, wherein the projectile has a tip, and at the rear this tip merges into a circumferential front guide band which defines the outside diameter of the projectile, and directly adjoining this front guide band in the direction of the projectile base, a circumferential case mouth receiving space which extends in the axial direction of the projectile and in which the case mouth engages is situated in the projectile. In order to reduce the twistless freebore to a minimum and build up the gas pressure early during firing, it is proposed that an exposed portion of the case mouth receiving space extending in the axial direction of the projectile is situated between the front guide band and the case mouth; i.e., the case mouth does not completely fill the case mouth receiving space in the direction of the nose of the projectile.

摘要： A cartridge casing having an open neck at one axial end and a closed rear portion at the other axial end to form an interior cavity for propellant. A projectile within the open neck to seal the cavity so the bullet is released when the propellant is primed and ignited. The projectile has a proximate end releasably secured within the neck of the casing facing the cavity and exposed to the forces generated by ignited propellant. The remote end of the projectile is formed by a lead core while the proximate end has a transverse surface and is at least partially formed of an amorphous metallic alloy having properties of bulk metallic glass (BMG). Liquid metal alloy can also be used at the interface of a propellant chamber in a bore of a cannon and a cartridge-free projectile.

摘要： A three component bullet with a core retention feature and a method of forming the bullet is described. The bullet can include a jacket surrounding a core and a locking band disposed around a circumference of the jacket and the core. The locking band can be received in a circumferential depression formed in the jacket and the core such as by compressing the core to cause the core and the jacket to expand radially fore and aft of the locking band. The circumferential depression can include shoulders that are in compressive engagement with the locking band to help secure the locking band in place. The circumferential depression can include an inwardly-extending annular band of jacket material which embeds itself into the core material with the result that the core is locked inside the jacket.

摘要： A round of ammunition for use in a 5.56 NATO-specification chamber comprises a cartridge casing and a bullet having a casing engaging segment, a sealing band and a groove. The sealing band encircles the casing engaging segment. The casing engagement segment of the bullet is engaged within a bullet receiving opening of the cartridge casing with a rear surface of the sealing band abutting a front edge of the cartridge casing. The groove encircles the casing engagement segment. A rear portion of the sealing band intersects a front portion of the groove. A front face of the sealing band is substantially flat. An angle of the front face of the sealing band is approximately the same as an angle of a neck-to-throat transition portion of the 5.56 NATO-specification chamber.

摘要： A cartridge assembly for propelling a subcaliber penetrator through a gun tube which has a portion of the propellant charge contained in an annular cavity surrounding the sabot is disclosed. The annular cavity is defined by the scoop shaped front bourrelet, the aft bourrelet which has three radially extending support posts and bore riding shoes, and a combustible tubular case extension over the aft bourrelet extending forward to the front bourrelet. The assembly includes cartridge case having a multistrand ignition system having a plurality of flexible combustible ignition strand. The strands extend through the propellant charge in the case and extend between the posts of the aft bourrelet into the annular cavity to simultaneously ignite the propellant charge contained therein with the portion of the charge in the cartridge case.
