Corrosive?

While S&B does make non corrosive reloadable ammo if this is in a non descript box then I'd guess it is military contract and I treat any eastern bloc stuff as corrosive if military contract.

Brass cased bxn? In a green box? That seems a little unusual.

Are you sure the cases are brass, and not copper-washed? If they are copper-washed, you probably have this ammo.

If they are actually brass, you've stumbled upon an interesting find!
