I have a 16 minute raw video and it shows the same thing...with the first weapon.
The second weapon he uses, the ejects are more to the side and back. TGhey don’t disappear like the first weapon but I don’t readily see if\where they hit.
You can see the people he’s shooting with the 2nd weapon, bodies move.
The last one he takes two shots to the head of an already injured person and you see the skull be mostly going away.
You are a better man than I am, stylin19a, for watching and analyzing that. I can’t make myself do it.
Bless you.
