International Classification:

F42B 12/36

US Classification:

102513, 102502, 102367, 102370

Abstract:

Marking cartridge for conventional firearms that deposits marking media on impact with a target. The marking cartridge generally comprises a marking projectile containing a quantity of marking media beneath a frangible cap portion and having a more durable exterior surface adapted to engage the rifling of the barrel when fired. The marking projectile also may comprise a receptacle for marking media having a curled lip adapted to remove air during assembly and excess marking media to insure a consistent quantity of marking media is contained within the marking projectile. The receptacle defining a marking media cavity radially spaced from exterior bearing portion wall and having a mushroom shape. The marking cartridge also may comprise an extendable casing.

International Classification:

F42B 7/08
F42B 7/04

Abstract:

A shotgun shell has a polymer wad with a forward shot cup portion and a rearward propellant cup, the wad in a casing, shot in the shot cup, propellant in the propellant cup, and a primer in a head of the casing. The propellant cup having a plurality of fins extending rearwardly that open to a deployed position upon firing and the shot cup having a plurality of circumferentially spaced axially aligned linear slit segments that permit air to circulate and permit expansion of the shot cup.

Abstract:

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.
