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.

The invention relates to a modular charge container device formed of one or more combustible modular cartridges, wherein said combustible modular cartridge comprises two ends, a first end comprising a base portion and a second end comprising a top portion, wherein the combustible modular cartridge is formed using a substantially rigid and combustible material, said combustible modular cartridge comprises at least one wall to define a cavity, wherein the cavity further comprises at least one combustible canister, wherein said combustible canister comprises an energetic material.

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.

A separate-loading firearm uses a battery-powered electric resistance heating element to ignite a propellant charge. Both ignition reliability and ballistic reproducibility are enhanced when a first portion of the propellant charge is consistently and firmly packed into a cavity formed in a rear surface of a bullet. This first portion may be sealed in the cavity by a membrane. A second portion of the propellant charge is packed within a firing chamber so that it abuts both the heating element and the first portion of the propellant charge.

A power charge (12) for a setting tool is composed of a propellant (16) and an igniter (32) embedded in the propellant (16). The propellant (16) is a homogeneous mixture of combustible components, an oxidizer and an epoxy binder, which together provide a continuous mass of solid form. The propellant (16) has an exterior (14) which, together with an outward face (36) of the igniter (32), is exposed and provides the outer surface of the power charge (12). A protuberant rib (28) extends along the length of the exterior (14) in a spiral-shaped pattern and provides a stand-off spacer between the power charge (12) and the setting tool. The igniter (32) has a main body portion (52) and an annular-shaped protrusion (48) which extends laterally outward from the main body portion (52) and into the propellant (16) to retain the igniter (32) within the propellant (16). The entire power charge (12) is formed of combustible materials.
