Great Britain medal hope Peter Wilson steps up his Olympic preparations on Monday in the ISSF World Cup at the Royal Artillery Barracks in Woolwich.
Wilson, 25, is competing in the double trap event in which he is currently ranked number one in the world. The farmer's son from Dorset broke the world record at the Shotgun World Cup in Tucson, Arizona, last month with 198 hits out of 200.
But despite being seen as Britain's best shot for a medal at this summer's Games, Wilson said: "Tucson was one competition and from my perspective I'm just focused on the next competition. People can say I'm this or that but I'm just here to shoot clays, and to shoot as many as I possibly can."
He added: "I don't look at peaking too soon as a problem, in shooting you are only as good as your last competition.
"I'm world number one and world-record holder but in a week's time that could all be very different. I tend to focus not on where I've been but on what I am about to do."
The 10-day World Cup is doubling as the Olympic test event, with the shooting competitions to be held at the same famous venue in south-east London.
"It's incredible here," added Wilson. "It's amazing to be in Woolwich and I don't think I ever thought I would be shooting in a competition in London. It's a phenomenal range and everyone here who has had a chance to shoot on it is enjoying it."
The women's 25m pistol final was won by Kim Jang Mi of Korea.
France's Celine Goberville took silver with Lenka Maruskova of the Czech Republic landing bronze.
Highest-placed Brit was Julia Lydall from east London, who finished 56th.
