Field target is an outdoor airgun field shooting sport. Competitions are usually fired at self indicating steel targets placed between . There are two classes; Piston for spring-piston air guns, and PCP for pre-charged pneumatic air guns. In sanctioned competitions, the same competition rule set is used around most of the world. A small match can consist of 40 to 60 rounds, while the world championship consists of 150 rounds. It is common to use scope sights with high magnification and a short depth of field such that an adjustable parallax knob can be used to precisely determine the target distance. The target kill zones have three standardised sizes, which are 15 mm (placed between 12-23 m), 25 mm (placed between 7-37 m) or 40 mm (placed between 7-42 m). History The sport originated by the National Air Rifle and Pistol Association in the United Kingdom in 1980, and spread to the USA during the mid-1980s. In 1987, the American Airgun Field Target Association (AAFTA) was formed. During this time, the competition rules differed between the two countries. The first Field Target World Championship was held in 1991 with athletes from the United States and Great Britain. The sport spread to Norway during the 1990s, and to Germany shortly after. In 2011, the World Field Target Federation (WFTF) consisted of 30 national member associations. As of 2020, WFTF consists of over 40 member associations. Equipment Pistols are far less common than rifles in FT, and they are shot in special events designed to accommodate the differences in shooting style. In the UK, 0.177 inch (4.5 mm) caliber rifles are the most popular, as the higher velocity (relative to a .22" rifle of the same power) of the pellets means they fly with a flatter trajectory over the distances involved. One downside is that .177" pellets are very light and can be affected more by light crosswinds than the heavier pellets of a .22" (5.5 mm) rifle, in cases where .177 pellets and .22 pellets are traveling at the same initial muzzle velocity. Pre-charged pneumatic (PCP) rifles are more popular than spring guns as the much lower recoil provides more confidence in aim for most people. There are some FT shooters who compete at very high levels with spring guns, and a well-engineered gun, shot with some skill will be no less accurate than a PCP. There are some "dedicated" FT
