Abstract
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.
