Abstract
A device for loading a primer from a priming station into a primer socket of an ammunition cartridge case, includes an elongated track for longitudinally guiding a rectilinear primer strip through the priming station. The primer strip includes a series of longitudinally aligned receptacles, each of which holds a primer in an interference fit that prevents dislodgement of the primer from the strip. Each primer strip also has a plurality of laterally extending castellations or teeth that slide on a ledge over the track, and a reciprocating advancing member on the track has arms that interdigitate with the teeth to move the primer strip forward through the priming station as the advancing member moves in an advancing direction. A detent interdigitates with the teeth to hold the primer strip with a target receptacle in a target position adjacent the primer socket of the cartridge case, while a reciprocating punch pin transfers the primer from the target receptacle to the primer socket. The primer strips provide a compact storage member that safely and conveniently allows primers to be loaded into spent ammunition cartridges.
