OH< and if you really want to find ammo for it, if you go to some Vintage ammo web sites you will find plenty, but it won';t be cheap
, that is if you cannot find in more modern ammo sites!
this place seems to have some
Hsm Ammunition Hsm Cowboy Ammo .32 Win. Spec. 170gr. Lead Rnfp 20-pack
bomberix.com
and I would make sure your rifle is OK with smokeless powder and not need to use black powder, before shooting any ammo you have or get!
a few pic of some other older .32 calibers , not what your looking for, but just saying there's a bunch of calibers out there that fall into the vintage line up, and can be had if you look!
I have handy! and I also have some of the rem .32auto loading ammo! different animals HAHA!
