I found a few sealed pounds of some obsolete Vithavuori powder - "3NSM"
I took a look at some old Vithavuori and various reloading manuals but could not find any reloading data.
From what I could find on the net, this stuff is medium burn rate shotgun powder that is simular to N330, Greendot or International according to one post on another forum.
However, if anybody has any pistol (9mm, 38, 357, 40, 44, 45, etc.) or 12 ga shotgun reloading data in some outdated book sitting on a shelf, I'd greatly appreciate your help.
