The most common is across the course followed by F-Class and prone mid range. Across the course is shot at 200, 300 and 600 Yards.
Mid Range is shot at 300, 500 and 600 yards. find out what kind of competiton you plan to shoot and we can advise you on the best equipment selections. They are very different for the different disciplines.
