Elavenil Valarivan captured silver in the women's 10m air rifle final, falling 0.6 points behind Japan's Hinata Taichi, who set an Asian Games record of 253.0.
She entered the last two shots just 0.3 points shy, then zoomed ahead with a 10.4 to 10.6, and pushed again with a 10.1 to 10.2, but the margin never tightened.
Earlier, Valarivan joined Sonam Maskar and Vidarsa Vinod to clinch a team silver, giving India a double haul in the event while the trio edged out South Korea's bronze.
With two silvers on day one, India echoes its 22‑medal haul from Hangzhou and looks to turn the momentum into a record‑breaking tally.
The women's hockey side raked up a 19‑0 win over Uzbekistan, and the men's squad will now face Indonesia in their opener.
