I always find it fascinating that the back of his head was blown away, normally the result of a front entry. By always, I mean since I was in public school back in the 60’s.
Actually, it was more so the side; on the Zapruder film, Kennedy is shown slumping forward and leaning toward Jackie when the head shot came.

Actually that is consistent with a rear entry. We are talking a rifle here. The head is essentially a jug filled with water. Shoot a jug of water and the a very large opening results at the point of entry and it exits toward the direction the bullet came from, then the bullet travels to the other side and creates another at the side of the exit.
