Muzzleloader systems
First Claim
1. A muzzleloader propellant cartridge for loading in a 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 muzzleloader propellant cartridge without a projectile therein, the propellant cartridge sized for being received by the breech end of the muzzleloader, the muzzleloader propellant cartridge comprising:
- a cartridge cup portion comprising a polymer, having a forwardmost disk portion defining a blunt forward end of the propellant cartridge, and having a unitary wall portion extending rearwardly of the disk portion;
a polymer head portion having a flange portion and a unitary connecting wall portion engaged with the wall portion of the cup portion, the cartridge cup portion and polymer head portion defining an interior, the head portion having a central opening for receiving a primer; and
propellant filling the interior.

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.
