IIRC that's PRVI Partisan under a new name.
They make steel-case, Berdan-prime military and brass-case, Boxer-prime civilian loads.
If it's brass case, it's reloadable, but I've seen where the Nagants' Gas Seal system is supposed to eat the cartridge necks FAST.

You may find yourself buying a lot more brass than with another type of revolver, but YMMV.

Did some quick research:
7.62 Nagant is .295 bore
.32 S&W round is .312 diameter

This is safe?!
(I ask because I'm planning to own one in the not-so-distant future and want to be able to feed it!)

According to Wikipedia (that great storehouse of knowledge) there is "a rumor" that Wolf is adding 7.62x38mmR Nagant ammo to their regular product line sometime this year.

Of course, you can still only download the 2008 product lineup, so no confirmation is available, but it would be cool to have more choice, yes?
