Might have to add neck turning to that list.
I recently bought 500 rds of WW for my 300WM (all that was available at the time). It's been awhile, so I'm going from memory, but IIRC the necks were (worst case) .0110 on one side and .0175 on the other. A few were as good as .0120 and .0145 but most were really out. Turned them all to .0115.
They shoot fine now, but something you should keep an eye on.
BTW, they varied in weight by up to 8 gr., with the majority being within about 2.5 gr.
For comparison, I bought Nosler 300wm brass over a year ago (made by Norma at the time) and they were .0150 to .0155 consistently and weigh within .5 gr. Less than .002 neck runout. Flash holes were prepped. Primer pockets were good enough to not need attention. They were trimmed to consistent length and the necks were deburred and chamferred. They were sized to give me .002 tension so all I did was drop powder and seat bullets and they shot under .5 moa out of the box. I have heard since that their quality has decreased, but I have not verified that personally.
Having said all that, If I could have bought 500 rds. of Nosler brass like the first lot, I would have gladly paid more money not to do the prep that the WW required.
My .02.
