Muzzleloader systems
First Claim
1. A muzzleloader firing system comprising muzzleloader having a barrel with a breech chamber open rearwardly, a constriction portion at a forward end of the breech chamber, and a projectile bore portion with a bore forward of the constriction portion, the system further comprising a muzzleloader propellant cartridge without a projectile therein, the propellant cartridge sized for being received by the breech end of the muzzleloader, the cartridge comprising:
- a cartridge cup portion comprising a polymer and having a tubular wall portion and a closed end of the tubular wall with a converging portion unitary with the tubular wall portion, the cup portion defining an interior;
a head portion connecting with the tubular wall portion of the cup portion, the head portion having a primer centrally engaged in the head portion; and
propellant filling the interior and extending to the closed end;
the system further comprising a projectile sized to the barrel and further sized to not pass through the constriction portion.

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.
