Sweet...ever ran across any of that 10.4 ammo ??
In the days of the old west a 6 shooter was as common as cell phones are today and just annoying if they go off in a theater.

Not Yet. Found some on line recently at around $15 a pop, limit of three. Pun intended

I converted my Vetterli to centerfire and made cases out of Win 348. Sized the front with a 44-40 die and ground down a 348 die to size down the base area. The bullets are slightly under .41 in. Some of the published data on the round results in a cartridge too short to cycle through the magazine. You will need a powerful press, however, and the cases need annealing first.
Here's a drawing: https://upload.wikimedia.org/wikipedia/ ... i_1878.jpg

The conversion is easy because the Vetterli has a center firing pin with a U shaped striker on front for the rimfire. Just rim the rimfire tips and solder in a center pin.

Or you can emulate the American Indians and clean out fired rimfire cases and stuff moistened priming compound into the rim and let it dry. They used self striking match heads!
I swear by Jupiter Optimus Maximus .... in the army of the consul Lucius Quinctius Cincinnatus and for 10 miles around it I will not steal anything worth more than a sestertius in any one day.
