And the FBI did test the actual rifle.
Thank you for acknowledging that fact... ( Now I won't need to post the proof that you'd clamor for if I posted that)
Yes They did test the rifle before any shims were placed under the scope mount... And the bullets struck OVER FOUR INCHES from the aiming point at a mere 15 yards.... Since you may have trouble comprehending what this information means, Let me enlighten you... 4 inches off at 15 yards would put the bullets off target by TEN yards at a hundred yards....IOW JFK would have been in no danger and would have rode on to the Trade Center... But Abraham Zapruder might have been in danger of being struck.....
Of course this is a bit flippant and facetious, because it is based on the silly idea that Lee Oswald fired that rifle at JFK from the window of the TSBD.
First, you don't know whether Oswald used the scope or not. Second, you don't know the condition of the scope at the time of the assassination. Lastly, you don't know how much Oswald practiced with the rifle and could have made adjustments for any imperfections in the scope. The FBI found the rifle highly accurate.
Mr. EISENBERG - Have you any way of determining whether the defect pre-existed November 27th?
Mr. FRAZIER - When we fired on November 27th, the shots were landing high and slightly to the right. However, the scope was apparently fairly well stabilized at that time, because three shots would land in an area the size of a dime under rapid-fire conditions, which would not have occurred if the interior mechanism of the scope was shifting.
Mr. EISENBERG -
But you are unable to say whether--or are you able to say whether--the defect existed before November 27th? That is, precisely when it was, introduced?
Mr. FRAZIER - As far as to be unable to adjust the scope, actually, I could not say when it had been introduced. I don't know actually what the cause is. It may be that the mount has been bent or the crosshair ring shifted.
Mr. EISENBERG - Mr. Frazier, when you were running, let's say, the last test,
could you have compensated for this defect?
Mr. FRAZIER - Y
es; you could take an aiming point low and to the left and have the shots strike a predetermined point. But it would be no different from taking these targets and putting an aiming point in the center of the bullet-impact area. Here that would be the situation you would have--- an aiming point off to the side and an impact area at the high right corner.
Mr. EISENBERG - If you had been shooting to score bulls-eyes, in a bulls-eye pattern, what would you have what action, if any, would you have taken, to improve your score?
Mr. FRAZIER - I would have aimed low and to the left--after finding how high the bullets were landing; you would compensate by aiming low left, or adjusting the mount of the scope in a manner which would cause the hairlines to coincide with the point of impact.
Mr. EISENBERG - How much practice had you had with the rifle before the last series of four targets were shot by you?
Mr. FRAZIER - I had fired it possibly 20 rounds, 15 to 20 rounds, and in addition had operated the bolt repeatedly.
Mr. EISENBERG - Does practice with this weapon--or would practice with this weapon--materially shorten the time in which three shots could be accurately fired?
Mr. FRAZIER - Yes, sir; very definitely.
Representative BOGGS - There is no reason to believe that this weapon is not accurate, is there?
Mr. FRAZIER -
It is a very accurate weapon. The targets we fired show that. Mr. EISENBERG - Mr. Frazier, turning back to the scope, if the elevation cross-hair was defective at the time of the assassination, in the same manner it is now, and no compensation was made for this defect, how would this have interacted with the amount of lead which needed, to be given to the target?
Mr. FRAZIER - Well, may I say this first. I do not consider the crosshair as being defective, but only the adjusting mechanism does not have enough tolerance to bring the crosshair to the point of impact of the bullet. As to how that would affect the lead--the gun, when we first received it in the laboratory and fired these first targets, shot high and slightly to the right.
If you were shooting at a moving target from a high elevation, relatively high elevation, moving away from you, it would be necessary for you to shoot over that object in order for the bullet to strike your intended target, because the object during the flight of the bullet would move a certain distance.
The fact that the crosshairs are set high would actually compensate for any lead which had to be taken. So that if you aimed with this weapon as it actually was received at the laboratory, it would be necessary to take no lead whatsoever in order to hit the intended object. The scope would accomplish the lead for you. I might also say that it also shot slightly to the right, which would tend to cause you to miss your target slightly to the right.
