Abstract: A device for the accelerated loading of muzzle-loading firearms is disclosed. The device comprises a cylinder, having a plurality of vertically located bores, rotatably mounted to a base having a single through hole. The device is positioned over the muzzle of the firearm, facilitated by a countersunk hole in the base; the cylinder is rotated until a bore containing a prepared load is in position over the through hole. When this is done, gunpowder falls into the barrel of the firearm and the patch and ball are then pushed through and into position with a priming rod. The vertical surface of the cylinder has a plurality of transparent windows which allow the viewing of the interior of each of the cylindrical bores. Each of the windows is marked with graduations to indicate the volume of the corresponding bore which allows the accelerated loading of powder into the device and allows the user, when in the field, to visually verify the amount and condition of the powder residing in the device.
