Natascha Hiltrop of Germany took over the lead from Smith after three of the elimination rounds, 163.9 points to 163.5, and had slightly increased her margin to 0.7 as the two women prepared to take their last two shots of the main competition.

Smith scored 10.1 and 10.5, but Hiltrop could only manage 9.4 - her worst shot of the entire event - and 10.5, which meant both finished on 246.5 points.

In the shoot-off, Hiltrop scored 10.00 but the Australian won it with 10.1.

Bronze went to Taylor Farmer of the United States.
