Don't think u can reload blanks, but they do put normal brass up for auction from military bases. You can get 5.56, 9mm, 7.62, and some other calibers. Not sure what process you have to go through though to get it. They have huge hoppers of this stuff that goes out for bid, it's amazing the amounts that they have.
