Abstract
A measuring device for measuring the concentricity of cartridges (30, 31), more particularly rifle cartridges, is essentially composed of a main body (1) provided with chambers (2) for cartridges of one or a plurality of calibers. The cartridges are radially retained in the chambers by so-called diameter compensators (9) but rotatable about their longitudinal axis. In the area of the point (39) of the projectile, an access for a measuring means (3) is provided, e.g. a dial gauge, the latter indicating the deviation of the projectile from perfect concentricity by the magnitude of its deflection variation when the cartridge (30, 31) is rotated. An aligning device (4) that is preferably also provided allows to exert a lateral pressure on the projectile in order to obtain an improved concentricity.
