I’ve tended to expect at least one cull when buying 100ct or more of any brand of brass, except Norma, Nosler, and Lapua, and even these, when buying a few hundred, aren’t without fault.
That said, I buy 500ct of Hornady bulk repackaged 6 Creedmoor brass from MidwayUSA every year for the last 4 seasons, and when it’s available, I’ll order more this year. It’s as cheap as I can buy it anywhere (save ordering 5,000ct of my own direct from Hornady), and it shoots in the .1-.4’s with single digit SD’s, regardless of whether I anneal or not... so I’m not casting a stone at that particular house.
