Boy, that must be hell to live down if you're Italian and your name is Carcano. Sometimes erroneously called the Mannlicher-Carcano, the Model 1891/38, 38 for the year that model of the '91 was released, is a bolt-action rifle chambered in 6.52x52mm.

But its designer was Italian, specifically a Lt. Colonel Salvatore Carcano, not Austrian, as the Mannlicher moniker might infer. At first glance, it is understandable how the Carcano Model 1891 might be confused with another of that era's bolt-action rifles.

The Carcano resembles a German Mauser, and its receiver is similar to that of the M1888 Mauser. Carcano and Mauser stocks are similar in appearance. And the Carcano and the Mannlicher share the en-bloc clip, used to load the Carcano six-round magazine.

As determined by the Warren Commission, Lee Harvey Oswald applied his Marine Corps rifle training (i.e., with the M-1 Garand) to shoot the 35th President of the United States using M91/38 Short Rifle Carcano, Serial No. C2766, Nov. 22, 1963.

Only nine months before, Oswald had reportedly purchased the vintage Italian rifle by mail order from Klein's Sporting Goods. Although countless conspiracy theorists have muddied the historical waters surrounding this presidential shooting, most historians believe Kennedy died from a Western Cartridge, Co., 160-grain, round nose bullet(s) fired from the business end of an Italian military rifle, Carcano Model 1891/38.

Said rifle bore the markings: MADE ITALY, CAL.6.5, 1940 and the serial number provided above - C2766. Marks found on the murder weapon's stock resembled those in photographs taken by Oswald's wife in March of 1963. And a ton of evidence, despite Oliver Stone's and myriad conspiracy theorists' conjecture and postulates agree that the ex-Marine killed JFK. Jack Ruby's snub-nosed Colt Cobra .38 prematurely ended Oswald's life in the Dallas police headquarters on November 24, 1963, forever ending any chance of further conspiratorial revelations - or not - provided by Oswald.

The Warren Commission decreed Lee Harvey Oswald had acted alone, negating the alleged shooter's assertions that he was set up ("I'm a patsy...I'm a patsy!")

But as any hunter knows, exit wounds are significantly more pronounced than entrance wounds. Shoot a pumpkin or a watermelon and see how that works. So how does one account for the huge, gaping wound on the back of Kennedy's head?
