He participated in shooting at the 1900 Summer Olympics in Paris and won three gold medals – in the Military Pistol team and the Military Rifle team, and in the Military Rifle individual. He also won a bronze medal in the free pistol competition; fellow Swiss shooter Karl Roderer won gold. Participating in shooting at the 1906 Summer Olympics at Athens, Stäheli took five more medals – a gold medal, two silver medals and a bronze medal in the individual rifle events, and another gold medal in the team rifle competition. His nine total medals in Olympic shooting competition remained a record until the United States' Carl Osburn won 11, all in rifle events, between 1912 and 1924.
He won 38 gold, 17 silver and 10 bronze at the World Championships and 3 gold and 1 bronze at the Summer Olympics, but in 1900 Summer Olympics the events were valid as World Championship, therefore the total is 41/17/11.
