摘要: A telescoped type ammunition including a case inside which is housed a sub-calibre projectile equipped with a segmented discarding sabot, a propellant charge and an igniting device for the propellant charge, wherein the sub-calibre projectile incorporates a prolonged part receiving a tail fin able to move between a folded position against the prolonged part and a deployed position, the sabot retaining the tail fin in the folded position, the sabot encloses the tail fin to isolate it so as to prevent any contact between the tail fin and the propellant charge.

摘要: A projectile system has a projectile with a metal body having a first outside diameter, a forward end and a rearward end, a plastic base wad engaged at the rearward end, the plastic base wad of solid plastic having a first length and a second outside diameter, greater than the first outside diameter, and a rifled barrel having a third inside diameter at the tips of the rifling, the third inside diameter greater than the first outside diameter but less than the second outside diameter, and a fourth diameter at the root of the rifling greater than the second outside diameter. With the projectile translating along the rifled barrel, the metal body passes inside the rifling, avoiding metal to metal friction, while the plastic base wad fully engages the rifling, imparting rotation to the metal projectile.

摘要: A break open rifle and bolt action rifle having a barrel extension with a breech end for receiving a propellant charge, a muzzle end with an extended attachment structure for receiving a complementary attachment structure of a barrel, and a chamber disposed within and through the barrel extension having a first diameter at a first end and a narrowing portion adjacent a second end opposite the first end, the narrowing portion having a second diameter smaller than the first diameter, wherein the first diameter of the chamber is sized to receive the propellant charge therein, and the second diameter of the narrowing portion is sized to prevent the propellant charge from being further inserted past the narrowing portion, and to prevent a projectile from being inserted through the chamber from the barrel muzzle end. A bolt action configuration having dual diameter non-rotating bolt with an extractor and ejector mechanism for removing a propellant charge.

摘要: A fin-stabilized sub-caliber projectile adapted to be fired from a rifled barrel, the projectile having a penetrator with a tail fin assembly, a sabot arranged on the penetrator and having at least two sabot segments circumferentially joined to one another that are separated from one another after leaving the barrel by centrifugal forces acting on the projectile during firing. The sabot includes a main body and a front guide flange that is adapted to be supported on an inner wall of the barrel and a rear guide flange arranged at an axial distance. A connecting section of the sabot is arranged between the front guide flange and the rear guide flange and has a smaller outer diameter than the front guide flange or the rear guide flange. The sabot and the penetrator are joined together in a positive manner in a region of the rear guide flange.

摘要: An ammunition cartridge may include a cartridge body including a substantially straight sidewall defining a cartridge cavity. The ammunition cartridge may also include a cartridge base and a primer received within the cartridge base and projecting at least partially into the cartridge cavity. The ammunition cartridge may also include a propellant received in the cartridge cavity, and a sabot at least partially received in the cartridge cavity and including a sabot body having at least one sabot sidewall portion extending from a base portion to a sabot end defining an open-ended sabot cavity. The ammunition cartridge may also include a projectile at least partially received in the sabot cavity, and the projectile may include a front end defining a tip, wherein the sabot end extends beyond the tip and is configured to contact a preceding ammunition cartridge of a magazine without contacting a primer of the preceding ammunition cartridge.

摘要: Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end the propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end and seats against the constriction portion. The propellant containment vessel may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The containment vessel further comprises a primer mechanism that may be integrated into the proximal end of the containment vessel.

摘要: A projectile includes an ejectable cup intended to protect a base of the projectile from propulsion gases, the cup including a wall surrounding the base and extending to a position where the edge of the wall is pinched between a seal surrounding the body of the projectile and a collar, including an annular part centered on a first cylindrical seat having a first diameter. The first seat is separated from a second seat by a shoulder, the face of which is oriented toward the rear of the projectile, a gripping means pressing the seal against the annular part, which causes the radial expansion of the seal, pressing it against the edge of the cup.

摘要: An ammunition round for simultaneously launching multiple penetrators enclosed with a single composite sabot, without any nesting or physical contact between the penetrators. The composite sabot has petals which are engraved by the tube's rifling during launch to rotate the petals, without presence of a separate rotating band element. The petals are separated from the penetrator elements upon exit from the gun tube solely by centrifugal forces acting on the petals.

摘要: A firearm barrel has an elongated body defining a bore and defining a bore axis, the body defining a breech end and an opposed muzzle end, a chamber defined in the breech end and contiguous with the bore; the bore having an interior surface having a plurality of alternating lands and grooves, the grooves being surfaces separated from the bore axis by first radius, the lands being surfaces separated from the bore axis by second radius less than the first radius and the lands and grooves being straight elements parallel to the bore axis, such that no spin is imparted to a projectile propelled down the bore. The lands and grooves may extend from the chamber to the muzzle end. The bore may have a constant cross-sectional profile along its length.
