A large piece of JFK's skull was blown from the rear of his skull......As if he had been hit by a heavy hollow nose bullet . A FMJ would blow right through the skull leaving a small entrance and exit wound. Many soldiers survived being shot in the head by a FMJ bullet.....But none ever survived being shot by a 45 caliber ACP bullet.
Walt, this is the reason I question if an 6.5mm FMJ ball nosed bullet with impact velocity at 2000 ft sec, hitting just a very small area of a spherical object of brittle bone matter, on a tangent line, would shatter into at least 6 sizeable fragments, plus a few other smaller fragments, plus leave a trail of dust fragments in the brain.
I dont think there has been any experiment that shows that, other than the" Inside the Target Car"experiment, which has the WRONG trajectory line, because they dont have the head turned leftward as seen in Nix Flim and Moorman photo. They relied only on the side view from the Zapruder film at Z312 and that does not quite show how leftward JFKs head is actually turned.
