Does brass length matter? It depends on how precise you want to reload, but more importantly in relaying information. I stated that these are the measurements in my chamber and you should use a comparator and gauge.
Why brass length matters is, when using a OAL gauge your datums are actually the shoulder and the ogive but are measured from the base to ogive ( preferably ) or to the tip ( COAL ). If you take that measurement with two different lengths of brass when measured from base to shoulder you will get two different measurements.
I know it's common to share load data in COAL but I'm not a fan of it, it's imprecise information. That's why I gave MY info in MY chamber as precisely measured as I could given in a COAL measurement and of course there are always .002+- differences.
I hope my answer wasn't to confusing.
