I'd considered that possibility craigd. But the difference between the heel diameter and the major diameter is around .051", so the case neck thickness would be extremely heavy at around .0255". I also considered that maybe this was designed for use with a heavy sabot, and that the major diameter was intended to ride on top of the lands. Otherwise, leading would be a real problem without any grease grooves, unless velocity was pretty low. But the design does present some possibilities for building a lathe turned paper patch bullet mold.
