I use a Sinclair Concentricity Gauge on Nathan's recommendation. The case sits on top of two pairs of ball bearings for support & is simple & accurate. Really happy with it.

I ordered the unit from the states. here's the link to a Youtube promotional clip;

I looked at the design of the Hornaday unit & thought it was poor. I could see how it could give you errors & be miss leading as it relies on the base of the case being true from memory... not the smartest design in my view.

Cheers,

Jon



jon, i had similar thoughts about the hornady. the sinclair looks nice and simple, i was hoping to avoid buying from o.s.

Hi Ben have you thought of making one. have a look at http://www.ballisticstudies.com/Resources/Discussion+Forums/x_forum/18/thread/4476.html


funnily enough chris, yes i have, as i already have a dial gauge.
i was thinking a v block or marbles used in similar fashion to yours.
i like your design, simple and the steel is perfect for the magnetic base.

how have you found yours?
i think ill give it a go, if its not much chop it wont have cost me much.
