Well, we “dun dun it” – fired a tracer round into ballistic gelatin and captured it in slow motion video for the world to see. We fired 18 of the 20 rounds in the box (commercially-available repacked M856) to check for trace function and all rounds lit up brightly and quickly out of the muzzle. What was not expected, however, was for the tracer column to not have time to ignite prior to the bullet leaving the gelatin block. As you might imagine, it doesn’t take a bullet long to travel 10 feet + 10 inches in air and doesn’t take that much longer to travel 10 feet in the air + 10 inches in gelatin if the bullet doesn’t tumble inside the gelatin.
Most full-speed videos of M856 appear to show the tracer igniting almost out of the muzzle .. either our tracer failed to work or the trace-out-of-the-muzzle that appears on the full-speed videos is an optical illusion. We welcome your thoughts and comments.
