This was shot out of my dedicated Spikes upper. The ammo I was using was CCI Blazer. Let me just say that my Spikes absolutely hates CCI mini mags and Blazers. I get FTF/FTE using this ammo. This round was fired slightly out of battery. I remember seeing a puff of white smoke and feeling a gush of air on my left arm. The round didn't damage the rifle/bolt assembly/bdm magzine at all.
