I came across a case of it about 1990. Corrosive, but that which I shot was sure fire and decently accurate. Brass cased, berdan primed. After you fire it, clean everything the gasses touch with a water based solvent.
that's true. This ammo did not work hardly at all on my friends FAL. Would put a huge strike in the primer with zero luck of detonation. I tried it in my FALs and one would cycle 100% another would hang up once in a while with the same symptom.
