Storage problems meaning temperature swings and some flooding water. Not all was affected, but enough to make one wary. Just check it over carefully and get a test sample before buying a dozen crates.
It doesn't sound like a good sample to me. I don't get very many trips to the range because of time constraints with school and work. I don't want to risk one of my few trips being ruined by bad ammo. Maybe another time down the road when I have more opportunities. I think I'd rather take the money I was going to spend on the Iranian ammo and put it towards ammo for my M1A.
