A bore cleaning device is configured to clean a bore of a firearm. The device includes a cylindrically shaped cleaning pad including a solid, non-hollow core. The device further includes a propellant providing a force to push the cleaning pad down the bore of the firearm and a payload located in a bore-forward position of the cleaning pad. The device can optionally include a lower charge cap situated between the propellant and the cleaning pad.

A bore cleaning device is configured to clean a bore of a firearm. The device includes a propellant providing a force to push the projectile down the bore of the firearm, a cup comprising at least one hole in a bottom surface of the cup, a dense material within the cup, wherein the dense material is configured to deform and press radially outwardly against the cup as the propellant provides propelling force to the dense material. The device further includes a bore rearward charge cap and a frame. The frame includes a bore forward plate located within the cup, a frame leg connecting the bore rearward charge cap and the bore forward plate and passing through the hole in the bottom surface of the cup.

A system, device, and method for measuring the temperature of a chambered projectile within a firearm are provided. A test ammunition round may include a projectile, a sleeve, and a case including a first end coupled to sleeve, and a second end coupled to the projectile. A thermocouple may be located within the projectile, and an electronic coupler may be coupled to the thermocouple, and extends through the case and the sleeve and exits the sleeve through a slot for coupling to a data acquisition system.

A gas propelled munitions anti-fouling system has a case having an open forward mouth end, a rear end, and an interior, the rear end defining a pocket that receives a primer and a passage communicating between the pocket and the interior of the case, a quantity of propellant received within the interior of the case, a quantity of anti-fouling composition received within the interior of the case, and a bullet having a rear portion inserted into the open forward mouth end of the case. The anti-fouling composition may have at least one salt and at least one acid. The acid may be anhydrous. The salt may be sodium chloride or sodium nitrate. The acid may be anhydrous citric acid. The anti-fouling composition may have at least one abrasive. The abrasive may be stannic acid. The anti-fouling composition may be 50% salt by weight and 50% acid by weight.

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.
