Abstract: A portable maxi ball lubricator and dispenser for muzzle loading firearms which temporarily stores a plurality of maxi-ball projectiles for subsequent loading. An elongated preferably plastic frame is of generally rectangular dimensions, and it includes a plurality of spaced-apart bullet chambers defined at regular intervals. An internal grease reservoir defined in one end of the frame stores grease, and the grease is distributed to the bullet chambers by an elongated passageway system. The passageway system includes a tunnel interconnecting the grease reservoir with a first one of the chambers, a plurality of tunnels interconnecting adjacent chambers, and a relief vent which is in fluid flow communication between the last chamber and atmosphere. When a suitable deposit of grease has been accumulated within the reservoir, a thumb screw associated with the frame may be turned manually into the reservoir to forceably pump grease through the passageway system and into each of the bullet chambers.
