Wow, nice that you can be in possession of such an interesting piece of history there.
On the other hand, one has to speculate on how practical a .36 caliber bullet on top of 70g of Blackpowder would be?
That's a massive amount of powder in what amounts to a "Squirrel Rifle" caliber in those days.
I can visualize a small bore, full of fouling, that would require constant attention to keep clean.
