At the Oslo Games he competed in three events, two rifle and one pistol, with his best finish being 26th in the small-bore rifle, prone, 50 metres competition. He competed at two more World Championships, in 1958 and 1966, and one more edition of the Olympics in 1960. At the latter tournament, he was 24th in the free rifle, three positions, 300 metres event and 27th in the small-bore rifle, prone, 50 metres tournament.
