chapter III

that the assassin in all probability hit two out of the three shots during the maximum time span of 4.8 to 5.6 seconds if the second shot missed, or, if either the first or third shots missed, the assassin fired the three shots during a minimum time span of 7.1 to 7.9 seconds.[C4-795] A series of tests were performed to determine whether the weapon and ammunition used in the assassination were capable of firing the shots which were fired by the assassin on November 22, 1963. The ammunition used by the assassin was manufactured by Western Cartridge Co. of East Alton, Ill. In tests with the Mannlicher-Carcano C2766 rifle, over 100 rounds of this ammunition were fired by the FBI and the Infantry Weapons Evaluation Branch of the U.S. Army. There were no misfires.[C4-796]

In an effort to test the rifle under conditions which simulated those which prevailed during the assassination, the Infantry Weapons Evaluation Branch of the Ballistics Research Laboratory had expert riflemen fire the assassination weapon from a tower at three silhouette targets at distances of 175, 240, and 265 feet. The target at 265 feet was placed to the right of the 240-foot target which was in turn placed to the right of the closest silhouette.[C4-797] Using the assassination rifle mounted with the telescopic sight, three marksmen, rated as master by the National Rifle Association, each fired two series of three shots. In the first series the firers required time spans of 4.6, 6.75, and 8.25 seconds respectively. On the second series they required 5.15, 6.45, and 7 seconds. None of the marksmen had any practice with the assassination weapon except for exercising the bolt for 2 or 3 minutes on a dry run. They had not even pulled the trigger because of concern about breaking the firing pin.[C4-798]

The marksmen took as much time as they wanted for the first target and all hit the target.[C4-799] For the first four attempts, the firers missed the second shot by several inches.[C4-800] The angle from the first to the second shot was greater than from the second to the third shot and required a movement in the basic firing position of the marksmen.[C4-801] This angle was used in the test because the majority of the eyewitnesses to the assassination stated that there was a shorter interval between shots two and three than between shots one and two.[C4-802] As has been shown in
