Italy's Niccolo Campriani won the men's 50m rifle three positions gold medal Monday, cruising to victory in an Olympic record.
Engineering student Campriani added the gold to the silver he earned in the 10m rifle, beating South Korean Kim Jong-Hyun and hard-luck American Matthew Emmons.
Campriani started the final with an eight-point lead having, stormed through qualifying at the Royal Artillery Barracks with an Olympic record score of 1180 points.
He finished six points clear with a combined Games best of 1278.5.
Behind him there was a tense battle for silver, with Emmons -- trying to erase heartbreaking memories from Athens and Beijing -- lying second with a 1.6-point lead with one round remaining.
But Emmons produced the worst shot of the final, a 7.6, allowing South Korean Kim Jong-Hyun to steal silver with a 10.4.
Emmons at least nabbed a bronze, just 0.3 ahead of France's Cyril Graff.
Emmons won the 50m rifle prone event at Athens in 2004, but blew his chance on the final shot in the 50m rifle three positions at the same Games, and incredibly suffered the same fate four years later.
In 2004, Emmons shot the wrong target, and in Beijing his trigger finger slipped.
But after battling thyroid cancer, Emmons said he was just happy to find himself back on an Olympic podium garnering more hardware for the family trophy case to go with his own prior medals and those of Czech wife, Katerina.
"I thought my Olympic medal-winning days were over and I am going to enjoy being back on the podium," he said. "I would have liked better but I am happy with bronze.
"My vacation starts now," he added. "It has been a really tough couple of years for me. The pressure has been difficult to deal with.
