Forster claims the following functions for this tool: "Neck wall thickness, Case neck concentricity, and Bullet runout"
-Use a ball mic with a stop for thickness
-Their tool indicates only a small portion of eccentricity
-Their tool in no way indicates 'bullet' runout, nor cartridge runout
As far as bending loaded ammo to solve a problem? NOT scientific, or well advised...
Better to learn how to make & measure(to verify) straight ammo.
