The best concentricity gauge

[Chama]

Who makes the best concentricity tool? I am in a market for one, so I want to hear everyone’s opinions. Thanks.

The best concentricity gauge/tool is a good seating die. You’re welcome

I don't know about best, but one I would definitely avoid is the Hornady version.
I have the Wilson version. I do not think it's the best, but it's plenty good enough to tell me what I want to know at my current skill level.

100% spend the money there, like an inline.

WSnyder has the best answer but if you are curious get one that is quick to use and simple to adjust. I have one of the high-end ones with a rubber tired wheel and a DTI and a few thumbscrews. I also have a simple Sinclair with a lever and a DI. The Sinclair sits right behind the press up on a shelf and gets used far more often.

You want to hear everyone's opinion.
Don't buy one. Use this money for something else.
If your reloading practices are sound, your loads should be relatively straight.
Lots of shooters here have bought one early on and I'll bet most ( 99% ) are
sold or collecting dust.
Also, it hasn't been proven that a round that's .001 or .002 out of round
won't shoot straight.

I like the Sinclair and you can pick them on this site for 75 to 90 bucks .

I have an older Sinclair. It basically works but I think there are likely better.

I have the Sinclair. It's simple but works well. Mine hasn't been out of its' box in a lot of years. Listen to the save your money crowd and carefully set up a good set of dies, load and go shoot.

Same as my NECO.

I think a quality concentricity gauge is not just a useless tool to check runout of your loaded round, I check concentricity of sized case and with a nifty little attachment I can check neck wall thickness variation after neck turning, it's another tool I can verify that my reloads are uniform and consistent eliminating outliers and variations, the OP asked for "best" yet few posters are trying to justify the $$$ they spent on low quality tools that collect dust......garbage in garbage out.

^^^^
Invest in good dies.

I also bought one early on my journey to make perfect ammo, then bought a good seating die that I could adjust with my fingers and did not have to use a concentricity gauge again. But it's good to learn for your self and see how well a good seating dies works. I'm not sorry I bought one to double check when I am in doubt of my reloading skills.

I use mine mostly for curiosity.

In load development i do use it to make sure i have a straight necked case when finding shoulder bump & on a loaded round when finding jam & touch.
The Sinclair is simple and quick.
I also use it to measure bullets, i make a set up with Hornady gauge parts .

The Sinclair is a good one. It's simple and repeatable. The Redding slant bed indicator is another one I can recommend.

While the value of concentricity is something each person has to answer for themselves (trust the target ), the value of a good concentricity guage  really lies in being able to qualify dies, neck bushings and individual steps in the loading process.

Good shootin' -Al
