London 2012 Olympic hopeful Peter Wilson smashed a world record on his way to victory in the ISSF Shotgun World Cup in Tucson, Arizona.
The 25-year-old won the double trap men's final with a new record score of 198 hits out of 200 targets.
The previous record of 196 was set by China's Hu Binyuan in 2009.
Wilson said: "This is pretty special, I'm really looking forward to the Olympics in London and the home environment, it's an exciting prospect.
"I feel oddly relaxed considering the feat I've just achieved. I've had great support from the team around me and through the lottery-funded world-class programme at British Shooting."
Tim Newenham, the programme manager for the Olympic Performance Group, said: "Peter's performance in Arizona was outstanding.
"It's the culmination of thousands of hours of training, both physical and mental and the whole team can be very proud to have played a part in supporting Peter's work towards his world record.
"It's a great position to be going into the Olympic Games, where home crowd support for British shooters can play such an important role in boosting their performances."
