If your experience with firearms is limited to the A3 you fired at PI, we really can't talk on any kind of even terms.
If you've never walked Dealey to see for yourself the small size and narrowness of the area, we cannot discuss the physics of the shots.
If you've never thought things through completely, depended on others giving an opinion based on the ability to sell a good story, and not base your opinion on facts in evidence, we cannot even begin to discuss the reality of hard evidence versus potential theories.
This incident pushed me into the sciences for an education, it has provided me with a knowledge base to decide for myself the most likely versus the improbable. It has been a long journey through many books, conjectures, times at the firing line competing in rifle and pistol.
For all intents and purposes, anything I say will not convince you of any other option other than your unfounded beliefs. I cannot help you there, only hope you find your answers yourself, and not depend on others who produce entertainment as your answer.
"... So not only do you have a moving target but a sloping target. That means the trajectory is changing constantly." I'd better jump back in here and point out that I'd written in an earlier post that the movement and downhill slope of Elm street away from the TSBD was determined by the forensic investigators in both the Warren Commission and HSCA to be that President Kennedy's car didn't drift in the sight picture to any significant degree in Oswald's telescopic field of view.
Here's a computer-simulated picture of the view from Oswald's position to the distance at which Kennedy was initially hit with Oswald's second shot at 44 yards, accounting for the magnification power of the Ordnance optics 4x/18mm telescope mounted on C2766, the rifle that Oswald used to murder President Kennedy.
