I loaded 50 rounds of 308 and 50 rounds of .223 yesterday using Lee Collet Dies. When I was done I ran the loaded rounds through my Hornady Concentricity Tool. I was really taken aback! Some of the loaded rounds had as much as .0015" runout! As soon as I can find a hole deep enough, I'm going to toss those dies into it and get some decent equipment.~Muir.
