A device for loading powder and a projectile into the muzzle of a muzzle loading firearm. The device consists of a hollow cylindrical tubular body with a rod ("ball starter") attached for loading a firearm. The tubular body has an elongated bore or cavity that is preloaded with a measured quantity of powder and a bullet. The tubular body fits onto the barrel, with all elements in line with the barrel opening. To load the firearm, a pin which holds the powder and bullet in place must be pulled, and the ball starter pushes all the elements into the barrel, followed by a ramrod to prepare the rifle for firing. The pin is held by an elastic band outside the tubular body during loading and post loading it is removably repositioned and held in the cavity by the flexible band. The present invention includes a groove along its longitudinal side for storing the ball starter prior to use; the ball starter is held in place by a removable flexible band. In addition, cylindrical apertures in the side of the tubular body store additional primers. Finally, the opening that fits snugly over the barrel of the firearm is configured with an aperture that allows the device to fit securely over the front sight of the weapon.
