I've had difficulty loading the AA HS hulls as well.....and I also have a bunch of older AA hulls that I am hoarding as well.
For target loads, I think that the Remington one piece unibody hulls are probably the best: economical (i.e.free in most instances), can be loaded with a variety of loads, from target to hunting, and that is about all you can ask for. I use them for slug and buckshot loads as well.
As for the cheap Winchester promo hulls, I even use those....load them up as blanks for dog training.
