I'd LOVE to see you attempt the same 3 "easy" shots, without the pressure of a live and moving target.
A slow target moving directly away, no windage shift necessary. Not my opinion but computer reconstructions & marksmen aiming & firing the same Carcano rifle seem to bear this out.

I’ve stood in the book depository building right about where Oswald was; his actual window is blocked off but one can within 3-4 feet of it. On the roadway in Dealy Plaza there is a “X” painted to indicate where Kennedy was first hit. I could make one or two of those shots. A Marine trained rifleman could make all three. Whether he did or not is unknown but the difficulty of that shot has been over played
