Amazing how some of the older ones, like vintage 4831, last so well, much newer Vv powders not so much.
60+ yr old H-4831 shooting well, 10 yr old Vv n-133 going bad. Must have to do with chemical composition. Maybe later Vv powders have been improved and are better. Let’s hope so.

Yes it is.. I have at least 9 + lbs of Surplus 4831 --> NO problems. No brown residue. No acrid smell.
