BULLET AND CASING PROJECTILE FOR RIFLED BARREL
20210254954 · 2021-08-19 ·

A projectile for loading into a rifled barrel includes a casing having a cylindrical body, a forward aerodynamic end, and a free end opposite the aerodynamic end, the cylindrical body of the casing defining an interior cavity extending to and in open communication with the free end. The projectile also has a bullet sized to initially slidably engage the casing along a partial length of the interior cavity through the free end. Upon discharge of propellant, the bullet is forced to slidably engage the casing farther within the cavity, preferably such that an entire length of the bullet is housed within the casing cavity, whereby a circumference of the casing is increased such that the increased circumference of the casing catches barrel rifling of the muzzleloader rifle. This allows a smaller caliber bullet to be used in a fouled barrel, while increasing accuracy of the muzzleloader rifle.

DEVICE AND METHOD FOR OBTAINING A HORIZONTAL DISPERSION PATTERN
20210180929 · 2021-06-17 · ·

A payload container for providing a horizontal dispersion pattern of sub-projectiles suitable for combatting surface targets is in the form of a cylinder and includes at least two sub-projectiles arranged in a core enclosed by a container wall, wherein the sub-projectiles are linearly disposed. In addition, a projectile and use of the same include at least one payload container or a plurality of sequentially arranged payload containers displaced by a displacement angle relative to each other. The displacement angle is predetermined in such way so that the sub-projectiles are vertically lined at the time when the mechanical force from the carrier shell disappears and the sub-projectiles are spread to the left and to the right, providing a horizontal dispersion pattern.

Obturator, which is an integral part of the driving band, on an artillery projectile

A spin-stabilized artillery projectile having at least one driving band and at least one obturator, wherein the driving band contains at least one compensating groove, and wherein the at least one obturator is arranged in the compensating groove of the driving band. The cross-section of the compensating groove, is preferably trapezoidal, but can also be rectangular or square. As a result, a complete detachment of the obturator is achieved and residues are avoided.

Muzzleloader systems

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.

ENHANCED POLYMER MARKING PROJECTILE FOR NONLETHAL CARTRIDGE

Nonlethal cartridges adapted to be chambered in a firearm having a barrel that includes rifling are provided. In one example, the cartridge includes a cartridge case and a sabot that is telescopically coupled to the cartridge case and that has a sabot mouth. A projectile includes a polymer base projectile portion disposed in the sabot mouth. A polymer front shell projectile portion is coupled to the polymer base projectile portion and has an outer surface that includes a circular locking rib feature that forms an interference fit with the sabot mouth. The polymer base projectile portion is configured to engage the rifling of the barrel to impart spin stabilization to the nonlethal projectile when propelled from the sabot in response to the expansion of a propellant gas.
