My son in laws both bought 400rds of new Winchester 284 brass from Cablea's and when they started to prep their brass they found that the flash holes are crap!! They are oblong or oversized like they were drilled or punched crooked and then redone. Out of 400rds of brass there were only about 100 cased that were "Usable". When we took it back to Cabela's they had a couple of hundred rounds on the shelf that were the same way!!! Has anyone else found this in their brass???
