Team GB shooter Ed Ling has a chance to reach the final of the men's trap after a solid first qualifying stage at the Woolwich Barracks.
Buoyed by Peter Wilson's gold medal success in the double trap on Thursday, Ling lined up in the single-clay version.
He dropped two shots in the first round of 25 clays but steadily improved, firing 24 in round two and finishing with a perfect 25 for a score of 72.
It left the 29-year-old from Somerset three off the pace set by America's Michael Diamond, who was the only competitor to shoot 75.
Ling, who came fourth in the test event at the venue earlier this year after missing out on a bronze medal in a shoot-off, was eventually ranked 15th.
But with five shooters on 74 and a further seven scoring 73, he is in position to take advantage of any slip-ups on Monday and grab a top-six finish.
Ling was fortunate to miss a downpour which soaked two of the other qualifying groups, and after overcoming some early nerves he is confident of shooting well again over the final two rounds.
"With shooting anything can happen until the last target so its full concentration right until the end," he said. "I was lucky with the rain, I just got away with that one.
"It was the first round so the nerves were going a bit but I got that out of my system and I'm raring to go for tomorrow."
