Thread: Concentricity Gauges

Ha ha you don't see any improvements from using one. It just identifies the issue. You have to go back thru your process and find where the out of concentricity is being caused. Something that may not so easy. Some brands of dies induce it. Body dies for example are good at inducing it.

For some reloaders ignorance may be the best bet. Depends upon your end use how much importance you place on eliminating concentricity as much as possible.

I use a 21st Century brand gauge.
