There are no aluminum hulls, but there are a lot that use steel. These are easily reloadable - IF they are the better ones.
Worth reloading - Winchester AA, Remington - ALL of them, Federal Gold Medal. The cheap Winchesters, any of the European ones, Estates and the cheap federals are not worth the aggravation
Winchester AA and all Remington hulls can use the same wad - designed for tapered hulls; however, Federal requires a wad designed for straight-walled hulls
