Away from his day job as a mining engineer Andreas Kronthaler was an excellent rifle shooter who represented the Styrian regional shooting association in Austria. In 1984 Kronthaler won silver in the 10 metres air rifle at the Los Angeles Olympics, finishing just two points behind Philippe Hébérle of France. One year later he then won bronze in the same event at the World Championships in Mexico. Kronthaler also competed in the crossbow, winning five medals at the World Championships, including gold in the individual 10 metres event in 1985.
