India's hope for a medal in the men's 50m rifle prone event in the Asian Games has shattered as the country's shooting trio, including Gagan Narang, failed to advance to the finals at the Aoti shooting range in Guangzhou today.After securing two silver medals in the 10m air rifle event on the opening day including the team honours, Narang, was second-best among Indians. He could secure 24th rank with 587 points. Hariom Singh, was at 13th position by shooting 590 marks. Third Indian entrant Surinder Singh Rathod was 27th with a tally of 586. India's foreign coach Stanislaus Lapidus said while the performance was not up to the mark, the weather conditions too affected the Indians.
