Peter-

I will do that as soon as I can get out to the machine shop and gather the gear I've been using and making.
I have a swaging die in the lathe right now that I taper bored, then with it still in the chuck I've reformed some 20b Magtech brass down to the size and shape of these chambers.
The plan with that die is to contour and thread it to fit in to my reloading press and also to work with a set of hand tools that can fit in the rifle case.

It might be tomorrow or the next day before I get any images up here to help describe the process I'm taking on this project.

Thanks for the nice comment too!
Definitely do keep your eyes out for pinfire double rifles.
They're extremely rare, but for now they're still not too terribly expensive when you can find them.
The amount of work needed to get them running is nothing considering the satisfaction of using them out in the field.
This is very rewarding work for sure.
