Anyone had a chance to look at this tool yet? Been holding off getting the Sinclair tool and waiting to see what Hornady offered, what are your thoughts on these two?

I have not used it, but from the pictures it looks like a good tool at a reasonable price.

I have experience with 2 other concentricity tools - the Forster Co-ax Case & Cartridge Inspector (http://www.forsterproducts.com/Pages/inspector.htm) and the Sinclair concentricity tool (http://www.sinclairintl.com/product/5577/Concentricity-Gauges).

I find the Forster tool to be more useful for checking bullet runout of a loaded cartridge. The loaded round rests on the base of the case and the bullet tip. Rotating the cartridge and measuring on the bullet about 1/4" from the case neck checks the bullet runout. This is very quick and easy.

The Hornady tool (based on the pictures) appears to work in the same way, plus there is apparently a way to correct the bullet runout in addition to just measuring it.

With the Sinclair tool, the case rests on the base and on the body of the case near the shoulder. Any dents or lack of roundness of the brass case will appear to be bullet runout. I found the Sinclair tool to be harder to use to measure bullet runout.

What you found was that the Sinclair wouldn't mask your actual runout, like those pinning the ends..

Think about the arc a jump-rope produces. If you measure displacement from it near the ends held, your readings will always be low. This, I imagine, is why such systems seem so popular.
The Sinclair pins the center, moving the arc out to be indicated. No masking that..

Take your straightest ammo as measured on the fly-by-night gadgets and re-measure with a Sinclair to see the true runout remaining. Go ahead, pry your seated bullets around, but again, your ammo isn't actually straight till you see it so on a Sinclair.

Dented brass? Not sure how you do that really, but I suspect concentricity is a non-factor there. More important would be to start taking care of your brass.
