do you have a name for the V-block type or one could be had?I had one for a while and found that a standard v-block type gauge better indicates straight ammo.
I also prefer to make straight ammo than to adjust crooked ammo.
But, you can really have both with this: http://www.premieraccuracy.com/gauge-item.html
It's way better than the H&H
There are so many other aspects of most peoples reloading process that are far more important than a concentricity gauge. I’m not saying this is true of your process, but concentricity is so far down the list of things that truly matter with regard to accuracy. I have a gauge that is so dusty that it looks like I haven’t touched it in 3 years.Does anyone have any first hand experience with the H&H concentricity gauge? I like the idea of being to measure and then correct loaded ammunition.
Thanks.
I spent way too much time and $ to reduce my case neck and bullet runout. While I learned a lot and did significantly improve my runout, zero change on the target.There are so many other aspects of most peoples reloading process that are far more important than a concentricity gauge.
I couldn’t agree more with your assessment. I found the exact same thing.I spent way too much time and $ to reduce my case neck and bullet runout. While I learned a lot and did significantly improve my runout, zero change on the target.
This is good enough to show straight ammo: https://www.sinclairintl.com/reload...s/sinclair-concentricity-gauge-prod37479.aspxdo you have a name for the V-block type or one could be had?

These V-block type gauges are misnomer'd as concentricity gauges, but really they're runout gauges.
They provide total indicated runout (TIR).
There is an important difference that leads to where & why runout can matter.
As long as you have chamber clearance for your loaded ammo, runout won't matter.
It's when your bananas curve so much that they bind in your chamber that shots are thrown.
This, due to resulting chamber pressure points.
So runout can matter.
I have a fitted chamber in one gun, and so much as 1thou TIR would surely throw shots.
That kind of runout would be an extreme in that gun.
I have other guns, looser chambers, where I doubt 3thou bananas would hurt results.
Same here...it's a deep dark rabbit hole.....I spent way too much time and $ to reduce my case neck and bullet runout. While I learned a lot and did significantly improve my runout, zero change on the target.
I agree completely. There are a number of tools on the bench that rarely get used, but if I need them, I’m glad I have them. One of the first other tools that comes to mind is a bullet puller. I rarely use it. It just kind of hangs there, but every now and then I screw up and need it.I agree that a concentricity gauge isn't the most critical tool to have at the reloading bench, and is likely to see infrequent use. But there are a few tools that fall into that category. I haven't used my flat-anvil micrometer in a while, either, since most reloading-related tasks call for a ball mic. But I wouldn't want to be without it.
And there are a few advanced handloading situations in which measuring TIR is important. If you use an FCP IDOD/ADOD for neck turning, for instance, you'll want to verify that your pre-turn TIR is less than the amount of brass you want to remove, or you won't get a consistent result.
Specialized tools have their place, even if they're a bit dusty when we turn to them.
I've had a NECO concentricity guage for many years along with a Sinclair and one I made.An oldie but a goodie...
Runs brass as well as ammo.

While I completely agree that runout and concentricity is a tricky subject and it turns out there are more important things to worry about..., I think it is best to learn it early
