Finland's Satu Makela-Nummela set a new world record in women's trap qualifying at the International Shooting Sport Federation World Cup in Acapulco, but then failed to medal in the final after finishing fifth.
The 48-year-old former Olympic trap champion hit 123 of 125 targets in qualifying to reach the final in the Mexican seaside resort, but could not then match that same level in the medal contest.
Instead Italy's 2012 Olympic champion Jessica Rossi, who had qualified in second behind the Finn, took the first gold of the World Cup by hitting 45 out of 50 targets.
The 27-year-old, who is also a five-time world champion, beat Australia's Laetisha Scanlan and China's Deng Weijun who claimed silver and bronze respectively.
Scanlan hit 43 targets, while Weijun hit 32.
After her world class qualifying performance, Makela-Nummela was eliminated early from the final having hit 21 of the first 30 targets.
Only Wang Xiaojing finished below her, with the Chinese eliminated after 25 targets having hit 15.
Rossi gained an Olympic quota place for her country, as did Deng who finished third.
Also going ahead today was the first round of qualifying in the men's trap.
Another Italian, Massimo Fabbrizi, the London 2012 silver medallist, finished joint top alongside seven other athletes who all hit 50 targets.
Among the others to hit 50 were Nathan Hales from Britain, Turkey's Yavuz Ilnam and India's Prithviraj Tondaiman.
