I've got a large hefty bag and four 50Liter rubbermaid tubs of old AA hulls in varying state of use. Everywhere from once fired to 20 shots and counting.. Probably not what you're looking for though. I don't think I have enough of the once fired version to keep you happy. Have you checked Graf and Sons or Wideners?
I worked for an guy in high school who had been a major gun aficianado, and who was getting on in years, so he no longer did much shooting. At the end of my last summer before college, to say thanks for being a good worker, he gave me those four tubs full of trap loads, 200 punds of shot, 20K AA Wads, 25lbs of 700x, 25lbs of red dot and a P. Warren 8000B.
The extra hefty bag full is a collection of AA hulls that I picked up at the trap/skeet range over the years. Some are the "new" design some are the old. Unfortunately, they're a hodgpodge.
