    The case gauge will tell you a couple of things. If it's a rifle case, you'll be able to see if you've set the shoulder back or if you failed to resize properly. The completed round will either go in too far or not enough. But yes, basically it's a go or no go gauge, however, if close, the round may still fit in the chamber and fire.

    I had some .308 rounds that I set the shoulder back slightly. They fit in the case gauge, but were down just a hair. Not a big deal, since they chambered and fired in my M1, but it does add a strain to the extractor since they were chambering slightly more than they needed to.
