An improved cartridge loader of the type having a generally star shaped latch that cooperates with cartridge bores positioned within a casing. A first novel feature is a semi-automatic rotation device for the star shaped latch, which device causes rotation of the latch from a cartridge capturing position to a cartridge releasing position in response to an external force directed axially against a knob when the casing is restrained against rotational motion, and which device will not induce rotation of the latch unless the casing is so restrained. The semi-automatic rotation device is also manually operable to set the latch from the releasing position to the capturing position, and to return the latch from the capturing position to the releasing position, simply by manually rotating the knob. A second novel feature of this improved cartridge loader incorporates a resilient but stationary bore closure member that, preferably, defines a circular contact locus radially outward of the locus of points established by the cartridge bores' center axes. In one embodiment of this second feature the resilient closure member is normally out of contact with the cartridges, and in another embodiment of this second feature the resilient closure member is normally in contact with the cartridges, when the casing is filled with cartridges and positioned upright.
