[QUOTE="Mikecr, post: 636873, member: 1521"] But with all measurements, like math, something must be given (qualified). What's given in the 10x measure above is that the piece is symmetric, and straight. With these qualified, then concentricity can be determined with it. Makes sense. But cartridge cases are not machined. They are not symmetric, diametric, or straight. Nothing is given with them. An example would be like Rx1.2+W = .0017" (which means nothing at all). So your 10x device above would indicate nothing but runout on cartridge cases. [/QUOTE]
