While visiting my brother he said he had a large garbage can full of once fired AA hulls shot in the late 80's or early 90's. They are stored in his basement. I didn't look at them but wondered when they changed from old type to the newer one. He said I could have them as he won't reload shotgun shells. I liked AA hulls when I first started reloading but when they changed I stopped using them but don't remember when they changed! Anyone remember?
