Yes. It was made for loading military 303 ammo, but the lot of powder was rejected because of excessive muzzle flash. Tom bought all 25,000 pounds of it .
It is very similar to 3031 in speed. Use that data.
I had several jugs of it go bad. Turned orange, smelled like ammonia and very acid. Ate hole in the jugs and the steel shelves it was sitting on.
