I have been getting deep into reloading, I have a tendency to embrace things with gusto or not embrace them at all, this is no exception. First off, I realize that there is such a thing as overkill, especially without a custom rifle
(I have a new 700 5R) but I enjoy the pursuit of excellence for just that, the pursuit J
To date I have manages to get my reloading down well enough that I average 0.52 MOA at 300 yards (on average over last few hundred rounds). I have spend a lot of time and a lot of money on equipment (a lot for me anyway)
I have a very accurate glass enclosed scale that gets me to 0.02 grains, I have competition dies, a Redding instant indicator, a run out gauge/corrector (Hornady), Wilson seating die with arbor press. I practice as consistent a reloading process as I can. I sort bullets (weight and base to ogive). Each case is measured from base to Datum (DL) length as well as volume with 99% iso-alcohol (I have a neat item I made to allow this to be done with a deprimed, cleaned and reedy to go case, will add pic)
I hand turn the case neck thickness on each case, polish the inside case neck wall, deburr with 0000 steel wool Then ultrasonically clean each case, all after the obligatory vibratory tumble and primer pocket uniforming and deburring. I measure case wall expansion after seating as well as pressure needed to seat the bullet

My question is this. At the end of the process I have a lot of data. When I select the bullets and cases to match together, what would you find folks say is best sort order to use in properly grouping cases and bullets for consistent groupings.
My thinking is that these two are most important
Base to DATUM
I donít think that case weight is that important since I measure volume, my cases are all same COL (+/-0.001)
As far as bullets, I think the Base to Ogive is most important then weight (SMK is very consistent, I just look for the occasional, rare, outlier)
Any suggestions on how to best group the data so that like bullets, cases and eventually rounds, are near each other when I go to the range
BTW, I just started doing this in May, like I said, I have embraced this with a fair amount of seriousness.
All the best
