....And the weapon was not perfectly sighted. When the FBI began its testing of the weapon for the Warren Commission in early 1964, none of their shooters could hit the target, until they adjusted the sights on the rifle.
Well you're both right. The error at 80 yards was about 2", up and to the right (good enough for the job)
The only question was did Oswald know about the error.
1. He did and tried to compensate - which for the shot taken would actaully mean no effort to compensate at all - LHO just aims where he wants the bullet to hit and allows the movement of the limo "forward and to the right" (Sorry Kevin Costner momemt) to carry the aim point to the bullet impact.
2. He did not know and tried to compensate. If he aimed at the base of the skull, compensated perfectly and made the best shot of his life, then bullet three would have hit Kennedy in the exact point of the actual final shot.
Either way it's a non-issue
No rifle is perfectly sighted. That’s why one always has to zero the weapon for himself. One’s man perfect zero may be a miss for some one else.
There’s a real inconsistency in claiming that Oswald was a poor shot and cricizing the rifle for a less than perfect zero. Poor shots usually result in less than perfect zeros. That doesn’t mean though that the poor shot person cannot hit the target with his personal zero.
Case in point. Poor shots tend to flinch when they fire resulting in rounds that fly high and right. A poor shot may compensate by zeroing low and left. An expert would miss every time with such a zero but the poor shot might do fairly good with it at the distance where he zeroed. At other distances he won’t do so good since the amount of compensation is distance dependent.
Also, I heard that Oswald’s rifle was zeroed low and left.
