The cup assembly may be slidable on the bullet with an extended position and a contracted position, the contracted position having a greater diameter than the extended position. A contraction inhibiting member that requires shearing off of the member for contraction may be disposed on one of the components.
A shotgun cartridge having a weighted wad for controlling the separation point between the wad and the shot load. The wad having a tail portion and a nose portion with the nose portion shifting the center of gravity of the wad axially forward away from the center of pressure compared to where the center of gravity would be if the nose portion was not weighted thereby controlling the shot load separation and enhancing the shot pattern.
Ammunition comprising bullets having destabilizing mechanisms that, under ballistic phase conditions, create instability in the bullets resulting in failure of the trajectory of the bullet and/or the sustainable velocity of the bullets.

Shot shells with enhanced performance due to inclusion of an absorber between the shot wad and the shot payload. The absorber reduces the pressure within a shot gun's chamber during firing of the shell, such as by absorbing energy generated during the firing process, and may thereafter return some of the energy to the pellets as the absorber and pellets are propelled along the firearm's barrel. Accordingly, the absorber enables a shot shell to generate shot payload velocities that are greater than would be achieved without the absorber, typically at a lower internal chamber pressure. In some embodiments, the absorber has (1) a Young's Modulus of less than 2,000 psi (137.9 bar), (2) a compressive strength of at least 100 psi (6.9 bar) and/or less than 10,000 psi (689.5 bar), and/or (3) a tensile strength of at least 145 psi (10 bar) and/or less than 10,000 psi (689.5 bar).
A vacuuming device for neutralizing flammable powders. The device includes a container having an upper chamber and a lower chamber separated by a baffle, with the upper chamber being in fluid communication with the lower chamber proximate an outer annular region of baffle. A liquid such as water is disposed in the lower chamber, and an air jet drawn into the lower chamber via a vacuum inlet line. In one embodiment, the air jet passes through the liquid for generation of a tangential flow that causes the body of liquid to rotate within the lower chamber. The rotation in the lower chamber can also cause the air in the upper chamber to rotate, so that liquid droplets entrained therein migrate to the outer wall centrifugally. Flammable particles entrained in the air jet are wetted and neutralized.

An encapsulated propellant charge comprised a sealed combustible container comprised of a consumable material and having a substantially cylindrical shape. The sealed combustible container comprises a top wall, a bottom wall, and a side wall therebetween. The top wall, the bottom wall and the side wall define a chamber; which contains a propellant composition.
A projectile assembly comprises a base portion for receiving projectiles such as slugs and has an associated pusher plate at a rear end thereof for minimizing or controlling deformation of the rear end of the base portion during firing. The pusher plate has a disc with one or more axially extending projections that extend axially into the rearward end of the base portion thereby reinforcing the base portion and upon firing providing uniform axial deformation and/or obturation of the base portion with respect to a firearm barrel. The projectile assembly may be, for example, part of a shotgun shell slug cartridge, and provides enhanced accuracy over the prior art.
A bullet system including a bullet body with a tail portion engaged with a polymer cup that provides enhanced engagement of the barrel upon firing. The bullet system may have a radial retracted state that corresponds to an elongated axial state of the bullet system that allows the cupped bullet to be fed down the barrel at a reduced diameter with reduced engagement with the barrel. The radial expansion of the bullet system occurs upon axial length reduction of the bullet system by axial compression. The axial compression can occur upon firing of the propellant or when loading with the ramrod. The bullet system can provide a tactile seat force indicator tip insert within the tip of the bullet body that provides a tactile sensation when the bullet is properly seated against the propellant charge. A cutting edge may be provided for scraping the barrel upon insertion of the bullet.

Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The breech end accepts the propellant and means are provided to prevent breech loading of the projectile. A propellant cartridge conforms to a constriction portion to minimize ullage. A projectile is inserted in the muzzle end seats on the constriction portion. The propellant cartridge 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 cartridge may have a primer mechanism integrated into a proximal end. Projectiles have sliding components that have an axial elongate position and an axial shortened position and may be loaded with a ramrod having an engagement portion for each of the two pieces whereby the projectile doesn't prematurely collapse.
