Watching the video at .25 speed I would say the shots a little too far back also add in if the pellet hit higher than crosshairs its possible the pellet didnt hit any significant brain tissue. If you watch it at .25 speed the position of the head is also angled toward you its not completely broadside at least appears not to be.
I took this screen shot just before the shot goes off. The crosshairs might be slightly higher and slightly farther back at the trigger pull but even in this pic I would say too far back for optimal shot placement.
The red line looks to be the back edge of the skull. The yellow mark at your first hash mark of the reticle shows how little of the brain cavity the projectile would have passed thru if it hit where the first hash mark is even if it didn't deflect at all. The green mark is where I personally would have placed my shot.
View attachment 447110 Its easy to armchair this shot after the fact so dont take my opinion bad. This was a shot that needed to be quick and sometimes it may not be ideal. One of two things happened. First possibility is my judgement on shot placement is correct and it wasnt a lethal incapacitating hit and the yote shook it off and ran away. Second possibility is the yote did die and his buddy ran off with the body. Depending on the ground hardness and how the other yote took the body you may not see much disturbance.
