The vise sizing die should be straight forward,
But I still can not envision what you want made.
Regular reloading dies will not fit in any existing press.
The case diameter is about 1.40 inches so the threaded die would have to
be nearly 2 inches in diameter.
Using the Lee Loader system
As GLS says resizing should not be an issue for a single shot.
Easy to make a depriming punch
Easy to make a repriming punch,
Easy to make a wad seating punch (or just use the repriming punch.
So if you are shooting a single shot, no need to crimp
just use waterglass on the over shot card wad.
