Roca, since you have fired some 32 S&W long ammo out of it dont go back to origional nagant ammo. My friend owns a gun shop and i have heard all the stories about people doing that and it ruins your gun if you back to nagant, if you want to shoot a less expensive ammo out of your Nagant revolver i suggest that you get a 32 acp cylinder. I have a nagant cylinder and a 32 acp cylider and i love them both.
