Hunt Volition Repeater

The Hunt rifle is unique in that it paved the way for the future of leverguns. It's "Rocketball" ammunition featured a conical bullet that was hollow-based where the powder charge was held. It was ignited by priming pellets which were independent of the ammunition.

As far as can be determined, only the patent model was built.  It now resides in the Cody Firearms Museum.
