ww 2 pull down powder probably from 20mm.
Smells fine. Used some a few years ago in my 6.5mag and went bang just fine.Up until a decade ago I was still shooting Korean war era propellant. Now I shoot Vietnam era propellant that is inspected annually. Some fail and are destroyed.
I'd put that old 4831 the sniff test before I started loading ammo with it.
