THAT is not typical of ANY brass from RP or WW that's I've ever seen - and I've bought many thousands of cases over the years in those 'bulk' bags or 50 to 100 cases - from .458's and thin .45/70's through down to .22 Hornets- and they NEVER looked even remotely similar to those. At most, one or two cases might have a small dent and that's it.

Looks like someone did a stomp-fest on those.
