I have a bunch of 7mm Rem Mag brass for sale. It came from another reloader so I don't know much about it. It has all been sized, trimmed, annealed, and tumbled, so I can't tell you whether it's once-fired or not. I can say that it looks good and I would not hesitate to use it myself if I owned a 7mag. I checked primer pockets on some and didn't find any loose ones. They are all trimmed to 2.492", with a few being slightly short by no more than a few thousandths, and those are separated out. He was clearly detailed with his brass
One thing I will point out because it caught my eye, is some unusual marks on a few of them, on the body just above the belt. At first I thought it was incipient case separation, but I checked very closely inside and out, and it is absolutely not that. Apparently the fellow who shot this brass had some dings in the rear of his rifle's chamber at that point. It looks purely cosmetic to me, if you can see them at all. I've included a photo of some of the worst and most of them you'd need a magnifying glass to even notice.
There are 135pcs of R-P, 77pcs of FC, and 37pcs of WW-Super, for a total of 249 pieces. I'd like $74 shipped for them.
