Mr. Eisenberg. Do you have any shims with you, Mr. Frazier?
Mr. Frazier. Yes. When we received the weapon yesterday, there were shims mounted in the rifle. The one under the front end of the mount is in this envelope.
Representative Boggs. But they were not there when you received it originally?
Mr. Frazier. No, sir. These were placed there by some other individual.
Mr. Eisenberg. For the record, these were placed by the ballistics laboratory of the Army, a representative of which will testify later.
Now, turning to another possible source of error in aim, Mr. Frazier, if a rifle such as Exhibit 139 is sighted-in with the use of a target at a given distance, and it is aimed at a target which is further away or closer than the target which was used for sighting-in purposes, will any error be introduced by reason of the fact that the target is further or closer away than the sighting-in target?
Mr. Frazier. Yes, it will, because the bullet in leaving the muzzle follows a curved path rather than a straight path, and in order to hit a specific target at a specific range, it is necessary for the bullet to travel up and drop down to the target, rather than have the bore pointed right at the target at the time of discharge.
Mr. Eisenberg. Can you calculate the amount of error which would be introduced by a specific projectile?
Mr. Frazier. Yes.
Mr. Eisenberg. Have you made such calculations?
