ABSTRACT:
The invention relates to an adjustable cartridge case gauge comprising a head portion adjacent to the shoulder of the case and a foot portion adjacent to the surface of the breech, the construction being such that the distance between the head portion and the foot portion are infinitely adjustable. In order to minimize the number of gauges which are necessary for several kinds of cartridge cases and thus to minimize the costs for manufacturing and storage the construction should be such that the range of adjustment between the head portion and the foot portion is so great that all cartridges having the same diameter of the rear surface of the foot portion may be adjusted, moreover that the head portion coming in contact with the shoulder of the cartridge case is hemispherically configured so that independently from the caliber of the corresponding cartridge, the angle of the shoulder and the length of the shoulder, contact of the head portion at the shoulder is ensured and the distance between the head portion and the foot portion can be fixed at each position.
