Success came late in the competition for Orphanidis, as he placed second in his penultimate event, the rapid fire pistol. He scored 249 points on 20 hits in the event, finishing behind Joannis Phrangoudis. In the free rifle, Orphanidis defeated Phrangoudis and the rest of the marksmen to win an Olympic championship. His score of 1,583 was bolstered by a second-string score of 520 in which he hit the target with all 10 shots. The results for the first, third, and fourth strings were 328, 420, and 315 points, respectively. Orphanidis missed only three times out of the 40 shots; twice in the first string and once in the fourth.
