I have been loading pistol rounds for about a year, and just getting into reloading for my rifle. In reading and looking at products, my next purchase may be http://www.savoyshooters.com/hornady-050076-lnl-ammo-concentricity-gauge.html It checks for run out and has a way to correct it. Like I said I am new to reloading rifle so it would be great to hear from someone has one of these.
