I'd have to say the only "bad brass" I've encountered over my 40+ years of reloading were Remington, but not a lot of them. I had three boxes of Remington factory loaded 6.5x55 which developed neck splits, some on the first firing. Not the usual sort of split, from the mouth back, but a short crack opened up not extending all the way to the mouth nor to the shoulder, just a crack about 1/8" long. All three boxes were purchased at the same time.
More recently I bought 100 Remington cases for my newly acquired .35 Remington. On the first firing with a mild load, one case developed a very fine, raggedly shaped crack about 3/4" long midway of the body. No harm was done and there actually were 101 cases in the bag so I guess I got my money's worth but I've never seen a crack like that in the body of any cartridge case.
