I only ever went so far down that branch of the rabbit's hole.
I have used Lake City .308 brass for 3 decades. Yes, I typically ceiling off about 1 grain lower in any load.
I weight separate that brass +/- 1 full grain, going any finer increases "consistency of case volume" very little.
I am very precise about powder charge weights.
I stopped fiddling with primer pockets 2 decades ago other than crimp removal. No brushing or scraping, no cleaning, no "uniforming", no problems caused by this either.
3 decades ago I removed the crimps with a countersink cutter. About 15 yrs ago I decided to swage them back out instead.
About the same 15 yrs ago I started deburring flash holes.
I have always crimped rifle ammo because in the early days of feeding my BAR I tried the "better wisdom" of not crimping, and got bullet setback from feeding for my efforts. Shoved completely in cases.
I do not alter case necks except length, no reaming, no lathing. Deburring from trimming is minimal.
I never seat bullets out to any "preferred distance " off the rifling, because I have magazine lengths that do not permit it. Some of my loads jump .150" or so, and shoot sub-MOA.
I do try, where possible, to seat rifle bullets 1-caliber deep in the neck, minimum.
I just a month ago started fiddling with a concentricity tool (got a good deal), have not started formal testing any 'improvement' claims or 'fixing' yet.
I am a suspicious guy where marketers are concerned, and am of the opinion that easily 75% of the "must have" 'Precision' tools out there for handloaders are only of use to the top 10% of shooters (10% may be too many).
Of course, we all think we are in that 10%, or will be if we buy enough tools and measure enough stuff.
