Ignorant question for the list: Is there a practical solid-rocket propellant based on ammonium nitrate?

Define "practical".

There have been formulations based on PBAN and Mg, and they require the near-mystical Phase-Stabilized Ammonium Nitrate
  to allow anything close to long-term storage.

I've seen amateurs try to fire some test motors. They are hard to start, and seem to suffer lots of combustion instability.

But I've never tried one myself, so, YMMV.
