Cool video for sure!
But you need to brush up on some terminology
The AR bolt is not operated by the casing pushing back on the bolt. It’s a gas-operated rifle; a portion of the expanding gases made by the burning propellent is siphoned off the barrel, piped back to a boss on the bolt carrier which is, in turn, forced back, pulling the bolt with it, to extract & eject the spent casing, and then be force back by a spring to load the next round.
Keyholing is something different from what you described; what you saw was the bullet strikes moving upwards because of the way the rifle’s recoil caused the firer to move.
Keyholing is when the bullet tumbles in flight, and hits the target other than head-on (sideways).
I didn’t make the video, and agree on the terminology lessons. Bill, perhaps you could leave that information in the Youtube comments (https://www.youtube.com/watch?v=gD7pd03L43k) so the creators could get an education?
