In no way do I mean to diminish your hunting and marksmanship skills, however I think we should acknowledge how hard it is to get a head shot on a moving target.
Practice is required of course. Oswald was a military sharp shooter, the shot was at close range, and he had a scope. Oswald would have had no problem making it (he had 3 shots)
I probably couldn't make the shot today, I'm out of practice.
"I would say that as compared to other Marines receiving the same type of training, that Oswald was a good shot, somewhat better than or equal to--better than the average let us say. As compared to a civilian who had not received this intensive [military] training, he would be considered as a good to excellent shot."[1]
"Characterizing the four-power scope as 'a real aid, an extreme aid' in rapid fire shooting, Sergeant Zahm expressed the opinion that the shot which struck President Kennedy in the neck at 176.9 to 190.8 feet was 'very easy' and the shot which struck the President in the head at a distance of 265.3 feet was 'an easy shot.'"[1]
