World number one Peter Wilson is excited by the prospect of competing at the Olympic venue at the ISSF Shooting World Cup.
Great Britain's shooting team warm up for this summer's Games in the competition at The Royal Artillery Barracks in Woolwich from April 16-28, which doubles as the Games test event.
"It's the first chance I've had to get on the range - it's amazing," he said.
"I don't think I ever thought I'd be shooting in a competition in London."
Wilson, the world-record holder in the double trap, is hoping to end a 12-year wait for a British Olympic medal.
The last one came at Sydney in 2000 when Richard Faulds took gold but Wilson, from Dorset, is heavily fancied having smashed the world record on his way to victory in the Shotgun World Cup in Tucson, Arizona, in March.
Phil Scanlan, British Shooting's performance director, said: "We would be pleased to get one medal but we are hoping for more than that."
The GB Olympic team will be named in May.
