I made a post about a year ago asking if anyone had used the Hornady Concentricity Gauge that allows you to adjust bullet run out.Seems to be getting mixed reviews and folks are saying it measures run out different from other gauges out there.Wondering if anyone on the fire has seen / tried one?
Yup, bought on based on NRA review. It works as advertised. Now do you need one ? P-dogs at 400 yards, yes. Elk at 200, no. This assumes the rest of your equipment and components are the best.
