Kimberly Rhode blasted her way into United States Olympic history in the shooting competition at the Royal Artillery Barracks.

The 33-year-old hot-shot became the first American to win individual medals at five different Olympic Games when she triumphed in the skeet.

She was one of three American gold medallists, as Vincent Hancock made it a skeet clean sweep with victory in the men's event while Jamie Lynn Gray won the 50m rifle three positions.

America's other medal came in the shape of a bronze for the much-maligned Matt Emmons, whose final effort was by no means his worst last shot at an Olympic Games - but it was definitely in the bottom three.

The man who famously twice blew a winning position with his final bullet to miss out on the medals at the last two Olympics found himself in silver medal spot with one shot to go.

Having twitched in Beijing to fire a poor score of 4.4, and aimed at the wrong target when leading at Athens four years earlier, Emmons could be forgiven for being a little nervous.

And yet again the pressure got to the 31-year-old whose score of 7.6, out of a possible 10.9, was comfortably the worst shot of the final.

At least this time he held onto bronze but Kim Jonghyun was the grateful beneficiary as he snatched silver, one of five medals for the most successful country at the competition, South Korea.

Jin Jong-oh led the way with double gold in the 10m and 50m pistol while Kim Jang-mi won the women's 25m event.

Italy were behind the US in the medal stakes in third thanks largely to Niccolo Campriani, who followed his silver in the 10m air rifle with gold in the three positions, while policewoman Jessica Rossi smashed the world record with 99 clays out of 100 to win the trap.

Next came China whose successes included Yi Siling, who had the honour of claiming the first gold medal of London 2012 when she triumphed in the 10m air rifle.
