Abstract: A rapid action bullet reloading device for use in conjunction with any firearm utilizing a removable magazine is operable by either hand of the user with minimal effort. The device includes a sleeve, defining a main body, a lever hinged to the sleeve and a cam member operatively engaged with the lever. The sleeve is structured and disposed to receive the magazine in a releasably locked and registered position for the bullet reloading operation. The device is operated by squeezing the lever towards the sleeve body with one hand which rotates the cam member about a cam axis in a highly leveraged action. Rotation of the cam causes an integral finger extending from the cam member to engage and depress a properly positioned bullet into the magazine. A spring urges the cam member back to the relaxed position upon each release of the lever, whereupon a next successive bullet can be placed in registered position for loading.
