Yes, Dr. Young was mistaken about the nickname of JFK's limo, probably because the nickname "Queen Mary" was the nickname of the limos used by the previous three presidents (Ike, Truman, and FDR). An innocent, meaningless mistake.

You're not suggesting that because Dr. Young used the wrong nickname to refer to JFK's limo that this somehow invalidates his account, are you?

Just so no one is confused: SA Sam Kinney was driving the Queen Mary.  SA William Greer was driving the President's car. There were no bullets or bullet fragments found in the Queen Mary.

Head shot fragments hit JCs upheld wrist, AKA top of wrist. Nelly said she thought the third shot is the one that hit his wrist. Head fragment removes a possibility of slug shedding tiny fragments within the skull.

As part of an ongoing project testing the forensic/ballistic elements of the assassination. I’ve done extensive and redundant ballistic testing, trajectory analysis and forensic reconstructions. To test the head shot trajectory and fragmentation pattern, I shot three intact pig’s heads.  I had pre and post X-rays taken.  Using surplus 6.5 Carcano on one of the heads, the shot did not explode the head and left a relatively small exit hole (8-9mm) with minor skull fracturing.  A witness panel 2 feet behind the head revealed only a slight yaw and the x-ray showed no fragmentation/jacket separation.  The maintained its trajectory through the skull into the witness panel.

Then using .257 Roberts with a thin jacketed sierra matchking projectile at 3300 fps, it took out the occipital skull and most of the brain with it.  It left the characteristic lead snowstorm on the x-ray and the smallest of fragments on the witness panel.

I was a little uncertain as to the cortical thickness of the skull so I did a separate test shooting a 7 mm thick pork shoulder blade embedded on one end of a 8 inch ballistic gel block and pork ribs on the other end. The Carcano round made a 6 mm round hole in the shoulder blade, cut a straight path through the ballistic gel, and clipped the edge of one if the ribs leaving a perfect semi circle. The witness panel again showed a slight yaw and no fragmentation/jacket separation whatsoever with no deviation in trajectory.

I’ve long been skeptical of the trajectories of CE 567 and 569, so that was the purpose of the test—but I couldn’t get the Carcano jacket to shear.
