A variation of .0015" or greater indicates the needto re-size (see our Bench Rest ® turn the case neck (see our Outside Neck Turners on pages 13 and 17).Case and Cartridge Runout (Concentricity)The Co-Ax Case and Cartridge Inspector measures runout on both cases (at the neck,shoulder and body) and loaded cartridges (at the bullet, case neck, shoulder and body). ® Seater Dies (see page 30)may also improve concentricity.TipAlthough concentricity measuring tools may also be used to correct runout at the point of measurement, Forster Products does notrecommend this use of its Co-Ax Case and Cartridge Inspector because:Pushing on any point of the cartridge will move eccentricity somewhere else.Pushing on the cartridge in the neck area changes bullet tension, which should be kept as consistent as possible.Rather than waiting until the rounds are loaded then attempting to correct, we believe you can obtain better results by using a ForsterProducts Seater Die or checking and refining your cases at each step of the reloading process.forsterproducts.com23
