definitely take them back Tassie
I have had a good run with the winchester brass myself but I think because I have used once fired range pickup cases that I match grade prep before using
the worst thing I have found is the little splits they can have in batches because of being crimped but you trim that out
that is embarrassing that a brand will let them cases out the door with there name on them, no quality control at all
I have seen cases like the 1st and 3rd photo before but only in factory loaded ammo from winchester
even the 2nd picture with dented necks has ripples in the mouths from over tumbling, very cheapo brass
I have some used cases I will hunt up for you if you want them
