Yes, it is. You're going to shoot for .003 or less with 223 brass

I have the "old style" v-block Sinclair concentricity gauge, the current Sinclair gauge, and a Case Master. They're all good.

And I have tried the same peice of brass, using the same dial indicator, with all three gauges with pretty consistent readings.

Buy the one you like.
