most popular types of archery ranges include 3-D ranges, field ranges and indoor ranges. Components Firing point The firing point normally is at a defined point on the ground, and on a civilian range will usually be level and flat. Outdoor ranges without a covered firing point are usually grass, often on a slightly raised, flattened mound. Outdoor ranges with a covered firing point are usually concrete or tarmacadam. Outdoor military range firing points are not usually covered and may have other configurations, e.g., sloping, a gravel base or hole in the ground. A "fixed firing point" or echelon rifle range is where the targets are located at the various distances with the marksman or woman shooting from the one firing point. The most advanced rifle range of this design was constructed for the Commonwealth Games New Delhi 2010. The firing point cover can be as simple as a tent, to a frame with only a roof (to keep off rain or sunshine) to a substantial building with appropriate apertures to shoot through. Targets Civilian targets are usually made of paper or a plastic coreflute, sometimes with a canvas or hessian back on the larger long-range types. Most competitive targets are a solid black circle on a white background. The black circle may have scoring rings. Targets of other shapes may be used such as used in pistol (hand gun) target shooting. Reactive targets allow shooters to easily identify bullet strikes. This allows shooters to improve their skills by quickly being able to compare their aiming point and where the actual bullet impacted the target. Those who choose to use military surplus rifles in competition on firing ranges at set distances include bolt and semiautomatic actions, with targets used as per military standards, current and historic. The same applies for the matches they shoot. Other target types include a metal plate that is knocked over by the bullet such as in the air rifle sport of field target or handgun discipline of IPSC, and stationary metal plates of scaled animal outlines on which bullet strikes mark as well as those that mark the paint which is painted over again after scoring. Butts / backstop The butts / backstop is the area behind the target into which the shot impacts having passed through the target. Outdoor and sometimes indoor ranges have earth or sand butts. Indoor ranges can use angled plates
