Best Concentricity Gauge ?

[Chuckhunter]

Currently using an RCBS Case Master and I'm not happy with it's performance. I get way to much needle jump while rotating the cases even when I'm very deliberate and slow. Would like to hear what forum members consider the best tool and is there a gauge out there that takes finger contact out of play.

SINCLAIR

You can use a hand eraser to roll cases, but a finger works with practice.

If you have a drill press locate them on centers and turn by hand. Use a mag. base indicator. This will show all inperfections in the case and it's a cheap way to go.

Or you can also just roll 'em on a flat hard surface, like a sheet of glass. You will see if the tip wobbles. My view is, if it does wobble it does and you have to change something but why measure it, how does knowing the amount of wobble help you? I have played with a few of these tools and they all suck from the fact you get more movement from you touching the case than there is wobble, IMO. Plus, there is no cost using a sheet of glass and you eyes. Your eyes can resolve a very small wobble, both at the tip and in the neck area.

Neco. About the first one that was out there, so that's the one I bought. No regrets.
