I never thought about it that way. The cavitation from the neck wound was rather small, probably indicating a FMJ, while Kennedy’s head wound could have been from a hollow point or soft tipped round.
Bullets used by Oswald would not have caused the head wound - type of injury. Head wound (different) bullet came from a different angle too that Oswald would not have been able to make. The two gunman theory seems correct based on Menninger’s analysis - it just wasn’t a shadowy figure on a grassy knoll.
Menninger I understand has passed away, and so too has the SS agent who fired the head shot. If I am not mistaken, SS would not confirm the agent even though he was identified in a public picture standing up in the car behind JFK. SS refused to cooperate on virtually everything. Now the physical threats made by the SS / fedral givernment towards the Dallas medical examiner who had jurisdiction over the matter (JFK’s body) makes more sense. The SS knew what was going down and needed to get JFK out of there asap. The SS succeeded and the media was filled with a federalism issue. While important, was more of a decoy in my opinion that the SS welcomed. “SS [Accidentally] Kills POTUS They Are Supposed to Protect” ... I don’t think we can imagine how history would have changed had that been the headline.
“while Kennedy’s head wound could have been from a hollow point or soft tipped round.”
No , it to was from a FMJ. The heavy for caliber round nose bullet traveling at about 2000 fps ripped his skull open then changed direction( ricocheting)much like shooting into water at an angle. There were no metal fragments in his head like a expanding bullet would have left behind.
