A method and device for ascertaining the temperature of a propellant charge (22) and a method and device for joining together propellant charge modules (2) to form a propellant charge (22). The method and device for ascertaining the temperature of a propellant charge (22) includes at least temporarily arranging a sensor head (4) which is movable with respect to the propellant charge (22) in a cavity (7) of the propellant charge (22); and ascertaining the temperature of the propellant charge (22) at least while the sensor head (4) is arranged in the cavity (7) of the propellant charge (22). The propellant charge modules (2) are positioned between stops (9) and are joined together by movement of at least one of the stops toward the other.

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 method for manufacturing a housing enclosing a pyrotechnic charge and an installation for implementing this method includes inserting a pyrotechnic charge into a charging volume laterally delimited by a rigid cylindrical charging wall and into a lower part by a first element of the housing to be obtained; positioning a second element of the housing to be obtained of cylindrical shape above the inserted pyrotechnic charge and in the extension of the cylindrical charging wall. The second element has a lateral cylindrical wall of the same shape and diameter as the cylindrical charging wall and is able to cooperate with the first element, and jointly translating the second element and the cylindrical charging wall relative to the first element such as to make the second element cooperate with the first element and form the housing enclosing the pyrotechnic charge.

A muzzleloader cartridge comprises a case having an open rear end, a forward end defining a vent hole, and sidewall defining a plurality of perforations. The case defines an interior space with a combustible liner lining the interior space; a first propellant received in the interior space; and a second propellent having a different characteristic received in the interior space rearward of the first propellent.
