Norma "White Box" Black ammo

Got a pretty nice deal on 650 rounds of 9mm 115 gr FMJ ammo from Norma that has a dark case. Not sure it is even brass. Came in 50 round, white boxes. The color of the case kind of startled me...guess that's why they called it black.

Is it any good or is the Norma ammo that makes your gun come apart? Is it a steel case or can I reload it?

Thx
