Concentricity Gauges - Worth it?

First we would take a straight case ,with the machine shut off, loosen the die caps and rock the ram up and down on a straight case . The dies were two piece shoulder die and body die line them up on a straight case. If that didnt work , call the shop. Doug

Fun toy to have that helps you know you're producing good stuff.
It's not something that gets used allot unless there is a problem happening, a problem you don't know you have unless you test it on one.
If i drop a round while reloading I'll put it on there and see if i knocked it crooked. But i know my dies produce goods stuff so it's just part of my collection of stuff !

The one with the most stuff wins right !
