Hornaday Concentricity Gauge Reviews

I am thinking of using the Hornaday concentricity gauge that is advertised to "fix" bullet run out. Does this device work as advertised? Has anyone noticed any accuracy or velocity issues with rounds that have had their concentricity "fixed" as compared to those that did not require it?

Re: Hornaday Concentricity Gauge Reviews

The best way to fix runout is to use dies and techniques that produce concentric case necks and seated bullets. When you start trying to manipulate loaded rounds, you are probably creating more problems than you are solving.

Yes.......in a perfect world with perfect brass and perfect techniques and perfect dies, there would never be bullet run out.

But in the real world there is from time to time. So my question is, has anyone who has actually used the Hornaday device to correct bullet run out observed any difference in ballistic performance as a result?

Re: Hornaday Concentricity Gauge Reviews

My hunting bud has unit and I have used it. If I take ammo that he checked as .002 on my sinclair it may read .004. My sinclair read more accurate always. I have adjusted run out with various holes drilled in bench and treaked bullet with same success as hornady. But on my unit when it hits .005 results are hard to get, so now rather than waste my time, mark with sharpie and are rock buster rounds

Maybe that should be my approach. I just bought one & no doubt I am doing something wrong. I can measure it fine, but have not been able to change the runout of measured rounds.

yes, you can use the little screw to eliminate run out. any difference in "ballisitc" performance, no. accuracy, "some". best use of the tool is to find out WHAT to change to eliminate problem at the source.
