Abstract: The cartridge loader comprises a body formed symmetrically about a central, upright axis and is provided with a number (here six) of vertical flutes opening radially outwardly of the holder and extending from top to bottom of the holder. The flutes are on parallel axes equi-angularly spaced about the central axis and each is configured to receive a cartridge, rim-up, and in such fashion that only a relatively minor portion of the cartridge rim rests on the holder top. A plurality of spring-biased fingers, equal in number and spacing to the flutes, engage and retain the cartridges in the flutes. A downwardly movable plunger is actuated to move the fingers radially outwardly in unison to release the cartridges into the cylinder of a revolver.
