If I really wanted to hunt with expandables, I would call the local FIsh and Game Officers and ask. Like stated in an earlier post, they are the ones writing the ticket. That said, the way I read it, they are illegal for any game.
Regarding arrow grain weight, the minimum weights are established for safety reasons, BUT I have been checked in the field a couple of times, and I have yet to see the officer pull out a tiny arrow scale..
