This is my usual process for all of my brass:
Measure the case length of ALL cases and trim to min (trim-to length) if ANY are over this. Chamfer inside and out on the necks.
Tumble for a few hours, inspect for any defects like split necks, easier to see on clean cases.
Deburr flash holes and uniform them, my tool does both jobs.
Size the cases, whether it be neck or just bumping the shoulder, check for runout and sort them into groups. I don't know why, but my 264WM brass is notorious for having large amounts of runout before I even touch them from the bag?
Prime them.
Charge them.
Seat bullets and check runout again. I do the half seat, twist the shell 180º and seat all the way.
I call this handloading because every aspect of the process has been given as much attention to detail that I can humanly do without skipping any steps.
The other part of handloading is working up a load to get the very best accuracy you can from your carefully prepped brass. In small cases (up to 22-250 size), I like to load 3 cases in each weight and go up in .5gr increments, in large cases (308, 257 and up), I like to load 3 cases in each weight and go up in 1gr increments. Then, once I find the most accurate load, I load ladder tests in .3gr increments above and below the node, I look for wide nodes so that my vertical is fairly consistent at longer ranges.
Hope this helps.
Cheers.
