You may have an actual chamber gauge then. Wilson makes both "chamber" and "headspace" gauges.As for Toprudder's concerns.....I don't know. I just know that that the box of Federal factory brass I had (don't know if it was a bad batch) wouldn't plunk in the Wilson gauge. My reloads do. And my reloads auto-feed where the said Federal factory wouldn't.
