I do not know anything about reloading, but it seems that with the surplus of metal casings, the case being stronger and not prone to being bent etc, reloading would be economical on metal, but no one does it that I can find.
I have almost 1000k rounds of .223/556 that are metal and it seems such a waste besides recycling.
