Best Concentricity Gage?

[Randy L]

I'm getting ready to buy a Concentricity Gage for checking cases and loaded round bullet run-out. I'm hoping to improve the quality of my F T/R loads. Which do you prefer? Why? Thanks in advance for your input.

I just bought a NECO off this site. Received it yesterday. Looks great, but I have no clue how to use it. I am sure the 51 page manual will help.

There probably isn't a best. I have a 21st Century model, and it works as it should. I also have an Easton Aluminum arrow straightener that I can use in the same fashion, and it performs the same function.

I use the Hornay and the results from using it are really great. Don't know if it is easier to use than others, but it is fast and seems very accurate. It gets used every time I reload just to check runout.

I have a Accuracy One gauge. It is in my opinion the best. Has many features which made it the easiest to setup, adjust and use. But it is Very Expensive.
Second would be the 21st Century model with the new addition of the turning wheel. An excellent gauge which is less costly. I would check both of them out.

The Accuracy one with the turning wheel is the nicest one I saw or tried. Matt

+1 for the NECO

 

[Dusty Stevens]

Accuracy one from ctk precision is very nice. The neco is compact and works very well. I have one i bought used 20 yrs ago and still works well

 

[Randy L]

Thank y'all for the input. I'm currently leaning towards the 21st Century. It appears to have many features with a reasonable cost.

Hah! You must have beat me to the purchase on the Neco. I ended up passing on one of eBay at a killer price also. Still haven't decided on a concentricity tool yet, close.

I worked up a spreadsheet comparing the different "higher end" models. Most of these are my observations from studying the manufacturer's websites and videos on Youtube.

I may be off on some of my observations. There are more knowledgeable here that can chime in.

I wasn't intending on publishing this for outside use, but maybe it will provide some help to others.

I totally agree with waltk.

I tried both the Sinclair and Neco gauges and sent them back. Then I bought the Accuracy One gauge and I've kept it and been using it for about 3 years. I got it with the Shars indicator instead of the Mitutoyo, to save about $90. If either the gauge or the indicator were to brake today I would buy another today.

I am also into F-TR. When setting up dies I use it to find out at which step runout is being introduced, once the sizing die is set I only spot check. I check every round after the bullet is seated. It makes a slow and tedious job, fun and fast. I'm a happy little idiot spinning my bullets watching the needle barely moving. The savings of time alone makes it a good deal. I fire 3,000+ rounds a year so the cost of the gauge is negligible compared to the ammo.

If you haven't seen it in action here's the link to the video https://www.youtube.com/watch?v=UukFQTa6Gws

Kindest regards,

Joe

PS: I like Endyo's chart

me and my friend have 2 H&H. we love them as they let you straighten up the bullets. work wonders on factory loads. even lets find out we had a bad rcbs die that was getting necks out of round set back to rcbs and they replace them and also sent letter saying they couldn't believe how bad the die was.

I have the 21st Century and recently bought the optional wheel for it. Quite honestly, I can't get the hang of it yet. No proof, but, I feel the problem might be the 4 small rollers the case has to spin on. I've had my eye on the Accuracy One model and I would buy that if I was starting out. After typing and thinking(?) I think I will call 21st Century and explain my problem. Maybe there is something wrong with my unit.

 

[Endyo]

Thanks for the kind words Joe.

One note of the Shars horizontal dial indicator mentioned. The prices listed on my spreadsheet for the 21st century and the Accuracy One reflect purchasing a Shar from a third party vendor.

I thought I would share this info:

$28 shipped for the same indicator. Saves $$$ if you purchase here.

I have been using the Hornady for years. I found it "acceptable". From an engineering standpoint I understand the limitations.

however

The CTK/Accuracy One concentricity gauge is one to make me go to the next level in features.

Now that I have my mill and lathe setup, for every product like this I ask myself:
can I build it or my version of it
are their any changes I would prefer to make in my version
can I match the quality/precision
are materials and time spent worth doing my own

The biggest determining factor is precision+time+materials. I have the bullet tipping setup. I could not make that as well as they did.

It does look like I can make this gauge. There don't seem to be any "missing" features. I don't think I can match his quality. Time would be OK but I think I would come out better working on something else. Materials would be cheap.

So

I'm gonna buy one.

Thank you all for the great input and discussions. This is why I love this forum. I was leaning towards the 21st Century with the wheel, but the comment about having issues with it makes me think I might as well drop the coin for the Accuracy One Concentricity Gauge. I've not heard any negative about it other than cost.

[waltk]

It is Very Expensive. But a year from now you wouldn't think about the money you saved but
what a great tool this is. Buy once cry once. You won't regret it.

 

[cncmill]

This is what I use. http://premieraccuracy.com/video-2015.html I feel it is one of the best. I don't reload without it.

Randy, I can't decide between the 21st or the Accuracy One. I thought about going cheap and getting the Sinclair since so many people use it, until I realized it can't measure as many different readings and the 21st or Accuracy One.

I missed out on two NECOs because I didn't know enough about them at the time. It's hard to find Youtube videos on the actual use of them and they are supposed to have a 21 page instruction manual. YIKES.

I don't think you'll go wrong with either. I'm a little interested in the comment about the 21st century giving one user problems. Do note the Accuracy One has a knob to turn the main wheel, while the 21st doesn't.
