The reason why blunt force blows transfer a high percentage of their momentum to the target, and bullets don't, is all about surface area. Bullets use a lot of their energy penetrating stuff.
You apparently fail to understand that it took ENERGY to puncture a hole in JFK's skull on entrance and to blow out a 5 inch diameter hole in the back of his skull. Where did the energy come from? Obviously from the bullet. And it was the CHANGE in kinetic energy of the bullet. People's heads don't just get holes in them without energy being used to make the hole.
Energy to blow out the holes in JFK's head:
Change in KE of the bullet entering the head to exit: = 1/2 x mass x (velocity in)**2 - 1/2 x mass x (velocity out)**2
The xrays showed some mass of the bullet was left in JFK's head but for first approximation, lets neglect that small mass because it wasn't a significant percentage of the bullet's mass. So the bullet had to slow down to transfer energy to JFK's head because we all know that for problems like this, CONSERVATION OF ENERGY IS TRUE. What that means is that the bullet had to do work to blow the hole in JFK's head and therefore, the bullet had to slow down.
CONSERVATION OF MOMENTUM is also true in problems like this.
That means: TOTAL MOMENTUM OF THE BULLET AND JFK TOGETHER IMMEDIATELY BEFORE IMPACT = TOTAL MOMENTUM OF THE BULLET AND JFK AFTER THE BULLET EXITED JFK's HEAD
Momentum = mass X velocity
Because the bullet had to slow down to transfer energy to make the holes in JFK's skull and conservation of momentum is true, it means the bullet's momentum was transferred to JFK's head and body. Because the acoustical evidence proves with a 95% probability (or better) that the bullet that hit JFK's head was fired from the right front, it means that JFK's head would be thrown backward directly away from the gunman which is exactly what we see happened.
IF you watch Doug Horne's presentation on the forgery of the Zapruder film, you'll see that Dino Brugioni says that the today's Zapruder film is different than what he saw on the Saturday night after the assassination. Dino said the original was crystal clear throughout (but today it isn't because during the time shots were fired, it transitions to an obvious forgery that only a fool would believe is original). Brugioni also says that in the Zapruder film he saw Saturday night, he saw several frames with the cloud of spray from the head shot which is radically different from what we see in the forged Zapruder film we see today.

Statistically, it isn't possible that so many witnesses would independently give a similar description of a large hole in the back right of JFK's head if it wasn't actually there. It isn't possible for JFK's head to move backwards so fast without the bullet's momentum knocking him backwards. It isn't possible for the so many things outside of the gubermint's evidence and fixed investigations to show a single gunman
Instead of continuing to believe that a bullet blowing a large holes in JFK's head did not transfer momentum to the body, what does it all mean? In other words, why did the US government forge the Zapruder film? Why was it important enough for the US government to alter the autopsy photographs and maliciously attack witnesses who said there was a large hole in the back of JFK's head about 5 inches in diameter? ETC.
One of the main reasons Americans have been made fools of for decades is that they actually expect the presstitutes or the gubermint to tell them the correct answers. That is obviously not going to happen until WE THE PEOPLE laugh at their lies.
The JFK assassination has never been a mystery, it has always been a lie!
