Worlds fastest firing Airgun - Faster than Metal Storm?

In this video, I’m attempting to measure the rate of fire on an air-gun designed to be the fastest firing gun ever made. I show the gun firing at 1x speed with audio at the end of the video. And maybe, shooting a few cans a long the way. -Time Stamps - 0:00 Intro 0:10 Metal Storm 1:34 Measuring speed of Gun 3:41 2 Million rounds per minute gun 4:08 Measuring energy 5:50 Shooting coke cans 8:36 Firing in real time with audio
