The 23-year-old Chandela shot 208.9 in the final to clinch the top prize in women’s 10-metre tri-series event.
Chandela, who had secured a quota for the Rio Olympics, won her first gold medal of the tournament late Tuesday with a world record score of 211.2, to surpass the feat of Chinese Olympic gold medallist Yi Siling (211).
For her outstanding performance in the tournament, the rising shooter was awarded a Walther rifle, besides being crowned the best shooter (men and women combined).
After giving a tough fight to Chandela, Norway’s Malin Westerheim won the silver with a score of 208.4, while another shooter from her country bagged the bronze after managing 186.1.
In qualifications, Chandela shot 416.1 and was on fourth, and fought like a champion to emerge victorious in what was a tri-series match.
On the first day on Monday, Chandela was ranked 10th.
Having missed the train, she waited unsuccessfully for a bus when the temperature plummeted to -10 degree celsius, before reaching the venue through a road covered in snow.
The result marked a positive start for Chandela ahead of the multi-sport extravaganza in Rio.
Chandela had clinched the gold in the National Championships held last month.
She had won an Olympic quota place for India after winning a bronze in the ISSF World Cup in Changwon, Korea in April last year.
