摘要： Muzzleloader systems including a pre-packaged propellant charge with a primer and receptacle. The muzzleloader system may include a propellant containment vessel separate from the primer and the projectile and that doesn't contact with the projectile until assembly. The muzzleloader may be rear loading, with a constriction portion forward of the breech chamber. The propellant containment vessel may include a body portion having a forward opening, with a propellant charge disposed therein and a cap portion that is crimp rolled within the mouth of the vessel to seal the forward opening. The closed end of the propellant containment vessel may define a primer receptacle configured to receive the primer. The receptacle may define a depth that is less than the primer height so that, when inserted into the receptacle, the primer extends rearwardly beyond the containment vessel. The muzzleloader system may be configured to fire only specifically configured propellant containment vessels.

摘要： A system for firing reduced energy cartridges from a modern sporting rifle utilizes a bolt assembly weighing less than a conventional bolt assembly for such rifles and utilizes blow back for cycling the bolt assembly rather than gas operation. A bolt insert in a polymer bolt carrier of the bolt assembly has a projection that fits within a recess on the rear face of reduced energy cartridges. The reduced energy cartridges having a polymer casing, a rimfire power load for propellant, the power load recessed from the rear face of the casing. Tuning the bolt may comprise adjusting the weight of the bolt or the sliding resistance of the bolt assembly in the upper receiver. The bolt may be formed by metal injection molding with a polymer bolt carrier attached thereto.

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 muzzleloader firearm for use with a projectile, a propellant containment vessel including a prepackaged propellant charge therein, and a primer. The muzzleloader has a stock and a barrel supported by the stock. The barrel has a breech end, a muzzle end, and a barrel wall extending in a forward direction from the breech end to the muzzle end. A breech plug is at the breech end. The barrel being ported to transfer expanding gases from the barrel to the breech plug. A gas passageway in the breech plug directs expanding propellant gases to the propellant chamber behind the propellant vessel seated therein wherein the expanding gases can eject the used propellant vessel.

摘要： A cartridge comprising an elongate rifle bullet with a plurality of circumferential grooves having overmolded polymer therein defining embedded polymer rings. The cartridge further having a case and propellant. The polymer rings have an outer surface that is flush with, that is, conforming to the outer surface of the body. The polymer may have be selected to have a favorable coefficient of friction with respect to the barrel. The bands offering reduction of the metal to metal contact between the bullet and the barrel while not diminishing the ballistic coefficient of the bullet.
