Why load your revolver one cartridge at a time? With one slight twist, the HKS Speed Loader instantly loads all six cartridges into nearly any revolver. The principle is simple: Strong metal points hold cartridges securely in the loader until you release them into the revolver with a turn of the speed loader knob.
