[QUOTE="ds, post: 69774, member: 3050"] 7mmag man, If you are getting a concentricity gauge something that I have noticed on two Sinclair concentricity gagues is that the ball bearings on which the case rides seem to wear easily, they are chrome plated but I guess the steel inside is soft, on the two that I have seen the contact surface of the ball bearings starts to take on a slightly flat angle. just something to note. I use a concentricity gague, and batch ammo according to runout. I also know people who have gauges and use them more as paper weights, they have tried them and found no practical difference in their group sizes so dont bother. When they kick my *** in comps it`s hard to argue (tactical type comps). Truth is getting the best concentricity you can is never going to hurt. But also credit to Kraky 1, his last post also made good sense to me. I just find Redding dies work better for me and that is where I am happy. It is possible to take things a step further and have a chamber reamer made up to cut a chamber and then used on die blanks to give you a perfect die, sometimes with wildcats it may be the only way, but it aint cheap or O Neil dies for $180-240 each, (not 100% sure on that, the prices frightened me so I ran away).
