Britain's Charlotte Kerwood failed to make the final of the women's trap shooting.
The 26-year-old from Sussex was in the crowd at the Royal Artillery Barracks on Thursday to watch Peter Wilson win gold in the double trap.
But she was unable to emulate her team-mate with a second-round score of 19 from 25 shots ultimately costing her.
Kerwood eventually finished with a three-round score of 64, while Italy's Jessica Rossi led the way with a perfect 75.
Lord Coe watched the qualifying round with new Olympic champion Wilson.
