Do it all Concentricity system

[Uncle Ed]

Is there a Concentricity gauge that can not only gauge Concentricity but also can correct it that's worth a poop?

I have both runout gauges pictured below and the Hornady gauge has the ability to straighten the neck. BUT if you need to bend the case neck to reduce neck runout then you have a problem with the case, your sizing die or seating die.

So fix the problem BEFORE you need to bend the neck and find out where the runout is coming from.

Below Redding has a new concentricity gauge that looks interesting and better than the ones I have now.

I have purchased the Hornady gauge that corrects and wound up returning it when the lightbulb went off in my head after reading at this site that all I am accomplishing was pushing the bullet one way at one end and the opposite way on the other end. It ain't fixing anything.

What is the grinding process you use on your seating stems to match your bullets?

I order a custom stem from Whidden. I send them a bullet and in about a week I have a stem.

For which die?

For their micrometer top seating die. Whidden offers a bunch of stems for popular bullets or you can have one made for a specific bullet.

The first thing I notice about the Redding is the gauge is at the opposite end and your case would point the other direction I like that being left-handed mine work fine but are slightly uncomfortable I think I would like the Redding better I have they RCBS case master now

If you look at the holes in the Redding base of the new gauge, the gauge can be moved to either end of the base. Meaning for left or right handed reloaders.

The Redding slanted bed gage looks pretty good, when did that happen?

Now, if they had included a driving wheel and replaced the plunger dial with a lever test indicator it would be a good machine.

I may be the minority here, I’ve shot up to .007 side by side against.0015 with ZERO effect on accuracy.
So I just moved on to more important things.

Thats good news ,now I can start measureing the length and diameters of each grain of powder........lol

Thanks for the replies I think I'll get a Sinclair & see how bad or good my runout is before I go any further down this rabbit hole.
