Concentricity Gauge Needed

[Shynloco]

^^^^ Speakum da truth!!!

My other door stops protested so I had to use it for a trotline weight. Friends don't let friends buy Hornady concentricity gauges.,,,,,

Thats why its a door stop that I just can't bring myself to screwing over another reloader by actually selling it to some unsuspecting newbie. The experienced reloader know better and wouldn't touch it with a ten ft pole.

I'm really close to saying skip it altogether. Even for advanced reloaders, they're way down on the list in bang/buck. They come in handy every once in a while as a QA sort of tool, but don't expect it to make a difference on paper directly. I do like my 21st century one though. But it's rarely used. A LOT of other stuff comes first.

Well, I'm not sure I can completely agree with all of the above. Certainly, a Concentricity Gauge is not a priority for many people, unless you are chasing ultimate accuracy. One of the main concerns in Precision Shooting and Reloading, is controlling VARIABLES. That includes making sure that your bullets are aligned perfectly with the chamber of your rifle. The generally accepted variance in runout (concentricity) is .002 for most shooters chasing best possible accuracy and some demand even less runout. Of course a hunter could care less. But in my experiences in reloading and Benchrest Shooting, I have tested and found I shoot better groups when my runout is in the .002 (or less) category, from finished cartridge to cartridge. SO I believe using a decent Concentricity Gauge WILL make a difference in improving your score by using the CC gauge as a checker of the cartridges you have prepared and thereby controlling another potential variable that hurt accuracy.

I have a Forster. It's just about worthless.

What is wrong with it?

A loaded round is supported on each end measured somewhere in between. I'm not an expert but the 21st Century tool makes more sense.

For me concentricity gauges are useful for learning what equipment works best, and spotting problems that otherwise would be invisible. Without them you are basically flying blind. That being said, I do not think that you need to spend a lot to get satisfactory results. The basic Sinclair works, both for cases and loaded rounds. I do not gauge every round. Once I have my process worked out I find that the results are consistent. If you are driven to straighten, the H&H is very versatile, built like a brick and easy to use. To overcome issues that pop up when taking readings using a Sinclair I use two hands on the case.

Well,
This is a little bit like my snowthrower. I have one, but lately do not use it a lot, and whenever I was using it more often, it still was not alot. However, my driveway is kind of wide and long, and borderline at best on being able to be cleared by hand, and less possible as I get older. When I need it, I really need it a lot, and it is there, otherwise, it sits unused. Some tools, like my snowthrower, or a concentricity gage can not have a value placed upon them by frequency of use. When you have an accuracy issue, if you have a concentricity gage, you go get it, then check for a problem, then hopefully solve it and get on with making ammunition, only to be brought out again if a new problem arises, probably from new tools or components.

Well said Danny.

Agree. I also find them to be useful when setting up your sizing die to get concentric necks.
