Why load your revolver one cartridge at a time. With one slight twist, the HKS speed loader instantly loads all cartridges neatly into 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. This model holds 9 rounds of .22 LR ammunition and is compatible with the H&R 9 shot revolver and the Taurus 94.
