I bought 5k pcs of 40 brass a few months ago (LE range pickups from a retired LEO), and I just now got around to really checking them out. I know, that was dumb. I'd say atleast 75% look like this, and these cases spent 6hrs in my vibratory tumbler (walnut/nufinish).* Would you reload these? Will the tarnish/corrosion cause weak spots in the brass? I don't care about how pretty they are or aren't, I'm just not big on case failures. They were supposed to be for my USPSA 40 Major Load, so pretty high pressure stuff. There aren't any cracks, splits or bulges, and they looked pretty much the same before going into the tumbler.
