  • Patent number: 4862623
    Abstract: A quick loader for muzzle-loaded weapons is disclosed whereby a generally cylindrical body is bored to the desired caliber through the longitudinal axis and fitted with a removable sealing cap, containing a holder for a primer or percussion cap, at the upper end and a fitting for mating to the barrel of a weapon at the lower end. Immediately above the lower end of the body is a rotational valve mounted with the axis of rotation perpendicular to the longitudinal bore. The internal opening in the valve is the same caliber and concentric with the longitudinal bore in the body. When the valve is closed a moisture resistant central cylindrical chamber is created above the valve and below the sealing cap. A premeasured quantity of powder is placed within this chamber and a patched projectile is positioned above the powder and beneath the sealing cap. The device is fitted to the barrel of a muzzle-loaded weapon and the valve rotated to drop the powder into the barrel.
