ABSTRACT:
A firearm barrel cleaning cartridge that includes a hollow, cylindrically-shaped, closed back, and open front shell casing, at least one expandable, generally hemispherically-shaped, rearwardly-facing, and removable wiper, a propellant, and at least one wad. The hollow, cylindrically-shaped, closed back, and open front shell casing contains an internal chamber. The at least one expandable, generally hemispherically-shaped, rearwardly-facing, and removable wiper is contained laterally in the hollow, cylindrically-shaped, closed back, and open front shell casing and divides the internal chamber into a plurality of internal sub-chambers. The propellant is contained in a first internal sub-chamber of the plurality of internal sub-chambers. And, each wad is contained in a respective sub-chamber of each at least one remaining sub-chamber of the plurality of internal sub-chambers, so that when the propellant is activated the at least one wad exits therefrom alternatingly with the at least one expandable, generally hemispherically-shaped, rearwardly-facing, and removable wiper and thereby alternatingly cleaning, wiping, and expelling unwanted debris from an interior surface of a barrel of a typical firearm through a muzzle thereof.
