And Commission Exhibit No. 554, consisting of three shots fired in 6.5 seconds, which landed approximately 5 inches high and 5 inches to the right of the aiming point, all within a 3½-inch circle.
Mr. McCloy. The first one is not exactly 5 inches to the right, is it?
Mr. Frazier. No, sir. The center of the circle in which they all landed would be about 5 inches high and 5 inches to the right.
Mr. Eisenberg. Mr. Frazier, could you tell us why, in your opinion, all the shots, virtually all the shots, are grouped high and to the right of the aiming point?
Mr. Frazier. Yes, sir. When we attempted to sight in this rifle at Quantico, we found that the elevation adjustment in the telescopic sight was not sufficient to bring the point of impact to the aiming point. In attempting to adjust and sight-in the rifle, every time we changed the adjusting screws to move the crosshairs in the telescopic sight in one direction it also affected the movement of the impact or the point of impact in the other direction. That is, if we moved the crosshairs in the telescope to the left it would also affect the elevation setting of the telescope. And when we had sighted-in the rifle approximately, we fired several shots and found that the shots were not all landing in the same place, but were gradually moving away from the point of impact. This was apparently due to the construction of the telescope, which apparently did not stabilize itself—that is, the spring mounting in the crosshair ring did not stabilize until we had fired five or six shots.
Mr. Eisenberg. Pardon me, Mr. Frazier. Have you prepared a diagram of the telescopic sight?
Mr. Frazier. Yes, sir.
Mr. Eisenberg. I wonder whether you could show us that now to help illustrate the point you are making.
Let me mark that.
This diagram was prepared by you?
