I’ve tried it as described here, but there’s a much much easier way. Just grab one of your fired brass from the rifle you want to gauge, give the neck a little squeeze between your fingers, (or against a desktop if you have soft hands) and stick a bullet in the end of it. If it’s too loose, squeeze the neck a bit more. You can black the bullet with soot, so if it should stick in the lands and pull out when ejecting the case, it’s easy to see from the markings left in the soot exactly how deep it was pushed back into the case. Just carefully replace it in the brass manually down to the “rub line”, and you can still get your measurement. I generally get repeatable results within .005-.007″ variance using this method in a variety of barrels from .223 to .375 Lapua.

Why use a fire formed case? That requires having to think too much when doing your computations for seating depths. I fire form a case then re size it to the exact dimensions I will size my cases for reloading.. Example fire formed shoulder datum to base = X I like setting the shoulders back .001″ to .002″ to allow easy chambering and minimal case stretch. Setting the datum point back also pulls the neck back and reduces overall case length. You should make your tool case from one of the cases you have sized for reloading and then there’s no extra math involved.
