Abstract: The invention relates to ammunitions for weapons of all calibers. The inventive ammunition includes a bullet which has the same caliber as the weapon or which is under calibrated, comprising a center part (2) and a rear part (1) which can carry a fin (12). The bullet has a hole (5) which is drilled in the front surface of the forebody (4) in accordance with the axis of the bullet, containing an internally carried sub-projective (6) which is more rigid than the body of the bullet and is provided on the surface with several longitudinal ribs (7). The invention can be used for ammunition with sub-projectiles in all calibers of hunting weapons with a shotgun or rifled barrel.

Abstract: An ammunition cartridge comprises a full bullet 1 held in a primer socket D containing a propellant charge P. The bullet 1 includes an flechette 2 and a launcher 10 concentrically received on the flechette to allow relative translation. The flechette 1 comprises an flechette body 3 of hard material having a conical head 4, and a stabilizer 6 fixed to a rear of the body 3. The stabilizer 6 has an integral lip 8 which seals the bullet 1 in the barrel to optimize pressure build-up during firing. The launcher translates forward relative to the flechette when released from the primer socket D. The full bullet remains intact in flight. The launcher strikes the target first and transmits high energy to the target. Immediately thereafter, the flechette translates forward to penetrate the target.

Abstract: The invention relates to munitions for weapons of small, medium or large caliber. The munitions include a subprojectile combined with a launcher which fills the bore of the weapon and which detaches under the effect of the aerodynamic forces on leaving the weapon, the assembly being incorporated into a cartridge which furthermore comprises a primed case and a propellent charge. The subprojectile includes a body made of hard material, combined with an axisymmetric element including a front central nozzle communicating with at least two annular nozzles to channel the airflow.

Abstract: An ammunition cartridge has a casing adapted to hold a primer, a propellant charge, and a subprojectile encased in a multi-piece sabot (launcher). The sabot has, in the immediate vicinity of the subprojectile, an internal annular chamber separated from the propellant charge by a deformable or breakable partition wall having a reduction in its thickness or a groove in a predetermined area. This wall is designed to break away or deform upon firing. The sabot also has an external channel forming an external chamber with the inner wall of the casing. This external chamber is separated from the internal annular chamber by a single elongated external wall.

Abstract: A subcaliber projectile including a penetrator preferably made of tungsten eavy metal, and having a penetrator tip section and a section following thereafter and extending over the major portion of the penetrator length which is provided with an external thread (helical groove) or circumferential annular grooves to provide a form-locking connection with a discardable propelling cage sabot. To realize improved piercing power for the penetrator, the form-locking region is composed of annular grooves without a pitch, or of a fine metric thread having a thread valley, with a width of approximately one to three times the base width of the groove defining wall or of a thread peak. Preferably a more brittle material is employed in the front penetrator region than in the tail region, and a further indentation structure is incorporated in the first frontal thread turns or grooves of the form-locking region.

Abstract: A penetrator shell has at least a front and a rear high-density core element each having a front face and a rear and lying in a stack extending along an axis with the front face of the rear element engaging the rear face of the front element. The rear face of the front element and front face of the rear element are substantially complementary, part-spherical, and centered on the axis. Thus, the front element can rock or pivot on the rear element while remaining in contact with the front face thereof. A high-density main penetrator body is engaged against and extends axially rearward away from the rear face of the rear element. A casing sleeve is engaged snugly around the core elements and has a front end generally at the front element and a rear end secured to the main penetrator body. An aerodynamic tip is secured to and extends axially forward from the front end of the sleeve.

Abstract: The invention relates to hunting ammunitions each comprising a projectile actuated by the combustion of a propellant charge and characterized in that it comprises an annular chamber separated from the propellant charge by a partition comprising one or several brittle areas.

Abstract: The invention relates in particular to hunting ammunition for a fire-arm of the kind having a subcaliber bullet fitted with a feathering, the subcaliber bullet allowing for destabilization on its trajectory beyond a distance travelled outside of the fire-arm.

Abstract: A sabot arrangement is produced in accordance with an improved manufacturing method. The sabot arrangement includes a rotational symmetrical sabot body having a central axial bore and radial separating grooves or slots. The radial grooves or slots divide the sabot body into a plurality of equal segments. These slots nearly sever the sabot body into separate segments, so that a material bridge remains near a forward edge and a material bridge remains near a rear edge of the sabot body, which material bridges function as fracture zones.

Abstract: An improved subcaliber fin-stabilized penetrator projectile having a plurality of high density pre-penetrator elements mounted in axial alignment in front of a main penetrator body. A casing having a frusto-conically shaped inner axial through-bore is threadably mounted on said main penetrator body and said pre-penetrator elements are matingly mounted in said through-bore and have mating frusto-conical shapes. A ballistic hood is threadably mounted on the forward end of the casing. The main penetrator and pre-penetrator elements are made of a high density metal alloy.

Abstract: An improved nose construction for a subcaliber inertial projectile which is ired with the aid of a sabot. A hood or body is mounted on the nose portion of the projectile. The hood is made of synthetic material and includes longitudinally extending fracture zones and is of substantially cylindrical shape. The frontal portion of the hood is recessed and forms an air flow receiving surface. In lieu of a hood a body, made of a thermoplastic material or the like, may be mounted on the nose portion. This body is adapted to disintegrate as result of air friction. The presence of the hood or body on the nose portion of the projectile, as it exits from a non-illustrated gun barrel, avoids or at least reduces unfavorable air-streaming forces which destabilize the flight characteristics of the projectile and thereby favors a uniform separation of the sabot segments from the projectile. Such uniform separation reduces or completely eliminates undesirable oscillations during flight of the projectile.

Abstract: An armor-penetrating projectile comprises an outer substantially cylindrically tubular member of great length/diameter ratio and density, centered on an axis, and having an axially throughgoing bore defined by an inner surface and an axially elongated inner member of greater strength and elasticity than the outer member extending axially through the bore the full length of the outer member and having an outer surface in tight radial contact with the inner surface of the outer member at at least a plurality of annular locations spaced along the axis. This inner member can be a bundle of wires that is inserted through the bore after the outer member has been expanded by heat, then twisted and longitudinally prestressed to lock tightly in the outer member.
