I can't find anything on how accurate it was or if it could be fired twice even. All we really know s that it "fired" the one round. I'm taking his word that the cartridge even had a bullet in it.

It's certainly a long way off from a fully functional firearm as we know it. Not like the ones they show in the lead up to the short demonstration.
