    Hi Stu

    This is what I use to determine head space, pretty low budget - but once again 100% repeatable, so it does the job.

    The nut was off a concrete dyna-bolt and just happens to sit firmly around the neck, and quite nicely on the shoulder of the case and is longer than the neck, allowing me to compare one against another when setting up my dies.

    I've found the easiest way is to measure, then zero the vernier. From there it will show up as a variance (+ or -) in head space e.g 0.002'' etc..no maths required.
