"Also, what does one do with such a weapon if there is a misfire (dud round). How do you eject the dud?"

As I understand the action, you simply crank the cocking knob once more, and the dud is pushed out the bottom of the weapon.

All in all, it was a promising design, with not a few implications for the future. The caseless ammunition was a true innovation, which could have revolutionized firearms the way smokeless powder did. It probably still will, when someone else takes up the concept.

Such things do not die...they only stay (temporarily) dormant.

That was a promising design as you describe it. And far be it from me to discourage innovation in firearms design. :)

Even John Moses Browning had to start somewhere.
