Great Britain Olympic hopeful Elena Allen narrowly missed out on a place in the final of the women's skeet at the ISSF World Cup.
Allen, who was born in Moscow but hails from Newport, Wales, was an agonising one shot from reaching a qualifying shoot-off for the final.
The 39-year-old, who took double gold at the 2010 Commonwealth Games, was eventually ranked eighth in the competition which was won by Wei Ning of China after a shoot-off with Slovakia's Danka Bartekova.
British shooting chiefs will name their team for London 2012 next month after the tournament at the Royal Artillery Barracks in Woolwich, which will also host the shooting competitions at the Games.
Saturday will see British medal hope James Huckle attempt to cement his place in the team. The 21-year-old, from Harlow, Essex, will be competing in the 10m air rifle.
"I'm really confident," he said. "We have had some great preparation this year and we've all been shooting really well.
"As a team we seem to be shooting our best around this time of year.
"The Board will decide at the end of this event who goes to the Olympics, so fingers crossed!"
Friday's other final was the men's 10m air pistol which was won by Lee Daem Yung.
The Korean took gold ahead of Vladimir Izakoz of Russia, with Ukrainian Denys Kushnirov winning bronze.
