Neither aluminum nor steel should be reloaded. It can be and folks have done it, but often to their regret. On another board a fellow showed close-up photos of a ring of little pits around the chamber of his 45 Auto 1911 barrel. They turned out to be gas cut pits, same as you see on some old rifle bolt faces where they are caused by leaky primers. In this case, though, the steel cases he had been reloading had developed small cracks just forward of the head that had let the little gas jets out to blast the pits into the chamber. Aluminum will do the same thing. Neither is as malleable as brass, and resizing fatiques them quickly, causing the cracks.
