Abstract: The firearm cartridge speed loader includes a shaft, a reload cylinder, and a rotation limit assembly at an interface between the shaft and cylinder. The reload cylinder has a plurality of pockets or chambers to hold bullet or ammunition cartridges, and the shaft includes an interference wheel configured to selectively clamp the cartridges in the pockets by simple rotation of the shaft within the limits defined by the rotation limit assembly. The rotation limit assembly includes a rotation-stop pin riding in an arcuate slot that defines the limits of shaft rotation, and a spring loaded spherical ball that selectively engages one of two detents to lock the shaft into the clamping or releasing positions, the disposition of the detents corresponding to the defined limits of the arcuate groove.
