In four and a half decades of skeet shooting I've seen the brass heads pull off a lot of both 28-gauge and .410-bore compression formed AAs. A lot more then off Remington hulls, but the compression formed AA was around a lot longer. It seems early on there were base wad problems with the AA HS. If my Wife would only hit the lottery, I'd order pallets of .410-bore and 28-gauge STSs and never reload.
