I'm not sure if this will help but I stumbled upon some actual footage of
how bodies react to being shot in the head with a rifle. As graphic (and
sad) as this is, it's actually very illustrative of the extensor reflex
that occurs when an individual is shot in head with a rifle, as was the
case with JFK's fatal wound, the so called "back and to the left". As
further correlation with JFK's assassination, the AKM being used here has
a muzzle energy of 1600 ft-lbs, utilizing a 123gr 7.62mm bullet with a
muzzle velocity of 2400 fps and at this range the drop-off is
insignificant. The Mannlicher-Carcano with the 161gr 6.5mm bullet has a
muzzle velocity of 2200 fps with a muzzle energy of 1700 ft-lbs, which at
100 yards drop to a velocity of 1900 fps and energy of 1300 ft-lbs (Values
from "Hornady Handbook of Cartridge Reloading, Fourth Edition", rounded
for simplicity). Given JFK's fatal head shot occurred at ~88 yards, these
are very comparable bullet energies at point of impact.
Note what is seen here in over a dozen examples where initial contact is a
head shot. The head moves forward a couple of inches and then the body
jerks backwards toward the shooter, sometimes violently and other times
less so but nonetheless all victims of an initial head shot involuntarily
move toward the shooter before becoming flaccid and forward head movement
is minimal. This is because of the brief decerebrate posturing
(opisthotonos in its extreme), which is an extensor reflex involving the
anti-gravity muscles that occurs in major brain trauma as seen in a rifle
shot to the brain, propelling the victim backwards.
Why "back and to left" still is touted as evidence of a shot from the
grassy knoll stymies me. This is basic neuro-physiology that any second
year medical student should appreciate on sight, yet CT buffs falsely
claim the "neuromuscular reaction theory" has been debunked.
Be forewarned, this video is real and graphically depicts multiple
assassinations.
