Four bullets were recovered from the body of Officer Tippit. In Nicol's opinion one of the four bullets could be positively identified with test bullets fired from V510210 revolver, and the other three could have been fired from that revolver. In Cunningham's opinion all four bullets could have been fired from the V510210 revolver, but none could be positively identified to the revolver--that is, in his opinion the bullets bore the revolver's rifling characteristics, but no conclusion could be drawn on the basis of microscopic characteristics. Cunningham did not conclude that the bullets had not been fired from the revolver, since he found that consecutive bullets fired in the revolver by the FBI could not even be identified with each other under the microscope. The apparent reasons for this was that while the revolver had been rechambered for a .38 Special cartridge, it had not been rebarreled for a .38 Special bullet. The barrel was therefore slightly oversized for a .38 Special bullet, which has a smaller diameter than a .38 S. & W. bullet. This would cause the passage of a .38 Special bullet through the barrel to be erratic, resulting in inconsistent microscopic markings.
