Concentricity gauge - Hornady Lock-N-Load Ammo Concentricity Gauge

This a great product. Hornady offers up quality well made stuff and this is no different. I bought this because I had some ammo that I knew was not centered. It was easy to set up. Took a few cartidges to get the hang of it but was able to center the bullets in the cases. Very handy tool to have if you need a way to recenter your ammo
