Sorry I should have clarified, I use my hornady bullet comparator set. The 33 cal indexes close to the shoulder/body junction and the 30 cal at the neck/shoulder.
All your using the numbers for is to get a before and after sizing measurement so using an actual headspace gauge is not necessary.
You can also use sizing bushings if you have th right platform..just sayin'..lol
In reality using one or the other is good because you know the datum point is rarely actually used in those tools. Using the same 350 on a 6.8 vs. a 6.5 Grendel can't possibly be hitting in the mid point unless it was sheer luck.
Since the whole shoulder will be bumped XXX 0.000's it really doesn't matter where we measure but the approximate mid point is much easier to visualize.

Bingo. I only use 2 index points on these cases due to the 6.8 die does not size that small portion of the shoulder on the 6x6.8 case. It allows for me to get that new portion of shoulder much closer to where it should be once fired in the chamber. I also like it because I setup my bushing to give a false shoulder for 0.001 or so crush on new cases. Its really not needed but on my new sea/nosler brass, they are almost 0.010 shorter headspace than the fired cases in the 6x6.8. This gives my OCD a bit of security in that I'm forming the shoulder not the web to this chamber.

Haha. Could have been in a past life! I'm very much a tinkerer and I don't always have the funds to buy the "proper tools" so as they say, "necessity is the mother of invention"
