In 1901, President Theodore Roosevelt appointed Brigadier General William Crozier as Chief of Army Ordnance. In 1904, Crozier assigned two individuals, Captain John T. Thompson of the Infantry and Major Louis Anatole LaGarde of the Medical Corps, to investigate and recommend which caliber should be used in any new service handgun. At the Nelson Morris Company Union Stockyards in Chicago, Illinois, they tested several types of handguns, calibers and bullet styles against both live cattle and medical cadavers. Before continuing, some definitions about the types of animals and the bullet types used in the testing are needed:
Animal Terms and Definitions Bull: Mature male bovine Cow: Mature female bovine Steer: Male bovine castrated before maturity Stag: Male bovine castrated after maturity The first day of live animal testing involved shooting eight head of cattle with rounds fired at selected target areas while timing the events. The time scale in the tables below is shown in minutes and seconds. The testing went as follows: 7.65mm Luger Weight: 92.5 grs. Style: FMJ-FP Velocity: 1420 FPS Energy: 340 FPE Stag Weight: 1200 â?? 1300 lbs. 00:00 - Shot through lungs left to right. 00:30 - Dead. 7.65mm Luger Weight: 92.5 grs. Style: FMJ-FP Velocity: 1420 FPS Energy: 340 FPE Cow Weight: 950 lbs. 00:00 - Shot through lungs three times. 01:00 - Jam; shot five times in lungs. Reloading break. Shot twice. Killed with hammer. 9mm Luger Weight: 123.5 grs. Style: FMJ-FP Velocity: 1048 FPS Energy: 301 FPE Cow Weight: 1100 lbs. 00:00 - Shot twice through lungs. 01:00 - Jam; shot six times in lungs. Reloading break. Shot twice in abdomen and twice in lungs. Killed with hammer. Cadaver testing: During the cadaver testing, the bodies were hung by the head and were shot at from distances of 3 yards, 37.5 yards and 75 yards. The target areas were fleshy areas, bone ends and bone shafts.11 If a round struck a fleshy area, only the hollow point rounds produced a bare minimum of sway, but if a bone end was struck, all the rounds showed similar results, though the .455 Man-Stopper and the .476 Eley were just slightly better.12 When a round struck a bone shaft, the sway produced enabled Thompson and LaGarde to give each round a subjective measurement; in short, they watched the body sway and simply gave it a number value for comparison purposes without setting a standard to compare it to.13 The table below details these subjective measurements: http://mwilson.hypermart.net/views/guns/1911.html#DEVEL <img border="0" alt="[byebye]" title="" src="graemlins/wave.gif" /> rk |
