SpyGuy ... I just bought some "tarnished" .308 from these guys and it looked like factory fresh ammo! ... a friend went for the "deal" ($9 a case cheaper) on the slightly dented .308 and couldn't see any dents! He also got some of their .223 and was very happy, but I haven't seen it myself.

AMAZING prices ... the only thing is that the manufacturers, at least on the .308, are mixed ... but on the bright side, they ALL grouped tightly around the same POI.
For this tip, I'd say you owe me one, but I actually found the link from an earlier post on TFL, so I can't personally take credit
Enjoy!
