Nice pistol! Never heard of one in that caliber. Lots of obsolete stuff out there.
I never got into reloading. I expect that's the only way to be able to shoot something like that on occasion.
TBH, I restrict my purchases to common calibers. I frequent Gunboards some as I like to learn about the old guns and military history. As I posted an Arisaka I inherited, I lamented that I cannot find any rounds for sale.
One of the guys has hooked me up with a few boxes of Norma. That will give me a chance to shoot it some.
I dislike a razor I cannot shave with, a cylinder which don't pop, or a firearm I cannot shoot! ;)
