This was from a drill called the Dickens drill. The parameters are from 40 yards taking 10 shots in under 15 seconds. I was shocked that I could do it in a little over half the allotted time. I apologize for miscounting at first, but due to my height I couldn't see the bullet hole just under the metal gong. I was using the 10 inch diameter gong as a point of reference for center mass. The 10th shot was high, but it possibly could have been a headshot. This drill was created by other YouTubers to honor Elijiah Dickens who stopped a mall shooting by taking out the gunman from 40 yards away with 10 shots in under 15 seconds per the reports.
