Ashab was the third shooter to be eliminated after he shot a score of 43, which was not enough to improve on his bronze in the same event in Glasgow four years ago.
The Delhi-born Shreyasi won the individual Silver medal in double trap in Glasgow and followed that by winning a Bronze medal at the 2014 Asian Games in Incheon. This has taken the country's overall medal tally to 24, keeping them at third position behind Australia and England.
She won gold in the women's trap event in the National Shooting Championships in 2012. The Indian hit the target twice while Emma failed to hit one out of the two shots she got. Shreyasi shot 96 in the finals and beat Australia's Emma Cox 2 shots to 1 in the shoot-off at Belmont Shooting Centre.
The other Indian in the competition Varsha Varman finished fourth in the event and missed the medal by a whisker.More news: Google India files appeal against antitrust watchdog over 'search bias' verdict
Om Mitharwal became a double medalist, after Heena Sidhu, as he had bagged Bronze for India with a score of 214.3 in Men's 10m Air Pistol Final on Monday.
Earlier, after topping the qualification stage with a score of 549, Om Mitharval suffered a letdown in the last two rounds of the final to finish with bronze in the 50m men's pistol event at the Commonwealth Games on Wednesday. He had claimed the gold in the 10m air pistol event and was gunning for a similar performance, but could not continue the momentum he has displayed so far in this year's Commonwealth Games. This was also her first CWG final.
More medals are expected to come as boxers Mary Kom, Vikas Krishan, Gaurav Solanki, Manoj Kumar, Mohammed Hussamuddin, Naman Tanwar and Amit Phangal are all going to take part in medal events.
