It Can be reloaded, But it is expensive!!
The bullet diameter is 329 and they are
only available as custom made!
I have only seen 2 companies that make them.
Since all factory ammo for it is Berdan primed,
easily Reloadable brass is a pain in the butt.
It can be formed from 7.62x53(54) Russian Rimmed
brass, but there are several steps involved.
p.s.
I think that Old Western Scrounger loads
hunting rounds in this caliber
