Blokesplaining why 3 round groups... aren't

EDIT: It appears that some viewers are confused by the fact that I am firing the gun, as if this has any impact on the underlying maths and the underlying point. Here it's explained again, but without any guns fired at all: https://www.youtube.com/watch?v=Ahp_bw5ZGjk
