The guy talking about the strobe light must have never seen an airplane at night. I wonder if he monkeyed with the video.

Either two guns or he loaded the last third of the clip with a completely different load (round weight vs powder). No way he could shoot both weapons simultaneously. I’m trying to thank of a way that he could move the rifle in and out of the window fast enough to change the sound that much. I can’t think of one off the top of my head.

The other sound files from other video's you can put them in a basic sound editor and visually see two different types of rounds firing simultaneously.

This one the camera man was much closer to the second shooter and it was distinctive without a sound editor.
