You might want to check the primer pockets. I used to buy Winchester brass exclusively, but things went to crap a couple of years ago. Primer pockets in both 308 and 223 were too shallow on about 10% of the brass, which was a pain in the azz. I also had several flash holes not centered (don't know if that matters much). I also had brass with a fold in the neck. For your sake, I hope they have gotten a grip on QC by now.
