I purchased this ammunition so that I could use a real gun for filming a "mock-shooting." I have developed a new pant for CCW and I need to illustrate the patentable features in video. There are not a lot of choices for 9mm blank ammo. I tested the ammo at 1", 18", and 36" from a paper target. At 1" it blew a hole through the paper. At 18" the ammo sprayed the target with small fragments. At 36" the ammo had no effect on the target. It is a single shot scenario . . . the slide does not cycle. This ammo performed well. It fed into the magazine and chamber nicely. I will buy this ammo again.
