During the investigation by the House Select Committee on Assassinations (1976–1978), the lead attorneys for the Committee, Robert Blakey and Gary Cornwell, were allowed to use WC-139 at an FBI firing range. The attorneys wanted to see how fast the bolt action could be operated. Blakey was able to fire two rounds in 1.5 seconds and Cornwell fired two rounds in 1.2 seconds. This was an experiment to test a possible theory that Oswald in his excitement may have pointed and fired, as opposed to aimed and fired. Some critics of the Warren Commission had claimed it was impossible to fire a Carcano rifle in less than 2.3 seconds. Both the CBS and HSCA tests proved conclusively that the claim was not accurate.
