If you do not reload most of what has been said is foreign to you, I determine head space first then form cases to fit and then fire, I do not have a clue what a 'ton of work' is. I will form cases for your 30/06 chamber that will be marked in '+', starting at +.010 (no-go gage +.001) to +.016 (field reject gage) +.002).
If you were familiar with depth micrometers or the versatile dial indicator I could send you ONE +.020 instead, with the dial caliper or depth micrometer head space can be determined in .000 (thousands) from .000 to +.020 on the M1917. simple reason, head space is A - B = C or the difference between two measurements, I am not particular as to how or where these two measurements come from.
If you have a dial caliper or height gage you can determine the effect the bolt has on head space, knowing this AND convincing someone it can be done when ordering a bolt that could fit is the though part, all that is required is to have the ability to measure the distance from the bolt face to the back of the lugs, to do this requires a cylinder that would allow the bolt to stand on it's face and a flat surface and or course a depth gage or dial caliper. The measurement is for comparison meaning the information is nice to know when done on one bolt, the information becomes useful when compared to the information of another bolt as in 'does one bolt have more or less effect than another bolt when compared, the effect will be in thousands.
