Abstract: A speed loader for loading a plurality of cartridges having shells into respective chambers of a revolver cylinder comprises a sheet form piece of resilient material formed with six substantially circular bores of diameter slightly less than the caliber of the shells. The cartridges can be fitted in the bores respectively and will be held in the bores by tension in the resilient material and frictional engagement between the resilient material and the shells of the cartridges. The six bores are arranged in two groups of three. The bores of the first group have their centers lying on a first arc of radius substantially equal to the radius of the circle on which the centers of the chambers lie, and the centers of the two outer bores are angularly spaced along the arc at approximately 60.degree. from the center of the inner bore.
