Apropos of this thread, I just noticed on the CMP forum mention of primer pockets shooting loose early and even case heads separating on more recent production .223 from Winchester. Remington complaints, too. One comment that Winchester was great in the early 2000's (I have a good bit of that brass and have had no issues associated with it). So, maybe the commercial makers have lightened the stuff recently to adapt it to the SAAMI spec. Not a good thing for AR shooters.
