  • Patent number: 4407086
    Abstract: Apparatus for removing a musket ball undesirably lodged in the breech of a muzzle-loading gun. The apparatus includes a ramrod to one end of which a ball starter is secured firmly but manually removable and to the opposite end of which a screw-jag tool is similarly secured. Using the grip of the ball starter as a handle, the tool is screwed into the musket ball and is then withdrawn through the barrel. To prevent rotation of the grip of the ball starter relative to its shaft when the musket ball is being engaged and disengagement of the ball of the ball starter when the musket ball is being pulled out, the shaft of the ball starter is keyed to its grip. Normally the ramrod is carried on the gun and the ball starter and screw-jag tool are carried in the pouch with the bullets and powder.
