Abstract: A primer pocket gauge tool for handloading ammunition is provided, in which the size of the pocket can be verified prior to installation of a specific primer thereinto. The device comprises an elongated member having a first end and a second end, the first end adapted to verify that the pocket meets the minimum dimensions for a specific primer, and the second end adapted to verify the pocket is below the maximum diameter for the same primer. The first end has a diameter and a depth marker to measure the diameter of the primer pocket and its depth, while the second end has a diameter equal to the maximum allowable primer pocket diameter for the given primer. The user verifies the pocket tolerances for a specific primer prior to installation. Also contemplated are individual maximum and minimum gauge members, and incorporation into a swage tool.
