The red blob on the Zapruder film is not supposed to be an exit wound with brain extruding from it, the red blob is the inner surface of a piece of skull that peeled outwards on the side of the face, hanging on by a piece of scalp. The actual large defect is on the top of the head, covered by hair.
Not according to the x-ray. That would also mean that the glowing orb in Z317 was sunlight reflected off a skull flap, which I don't buy. JFK's head exploded. I don't buy that a FMJ bullet can create 7 neat and tidy wounds while crashing thru bones and come out slightly deformed, while the head shot disintegrates and blows out a perfectly circular hole on the right temple of JFK.
BTW, your GIF stabilizes the frames anchored on the head. If you anchored it on the body then JFK's head gets violently thrown back and to the left.
The more I look at the autopsy photo, the more it doesn't match the hole in the x-ray or the Z film. The skull flap is too high on JFK's head, well above the ear. The autopsy photo is the anomaly here.
Look at the damage at Z323 that the FMJ bullet caused. JFK's scalp was blown backwards off his head from a shot from the rear. Are you telling me that a FMJ bullet did all this damage, then disintegrated into the ether, while the MB was only slightly flattened?
