Shooting accuracy
Svd possesses high accuracy for weapons of this type. The best pitch for accurate combat is 320 mm. Until the early 1970s Svd It was produced with such trunks. The snoop of 7N1 was at the same time 1.04 MOA (angular minutes). This is better than even many rifles (despite the fact that there are other things being equal, the self-loading rifle shoots). For example, the M24 sniper rifle is adopted in 1987 in the United States when using a MOA. However, with a 320 mm rifling pitch, it wasn’t much time to go. In the first half of the 1970s, it was 240 mm. Thereafter Svd However, it can be noted that, however, it was up to 1.24 MOA, and the conventional LPS cartridge (57-H-323C) was up to 2.21 MOA. For example, 320 mm.
With sniper cartridge Svd It is possible to see the following targets: head – 300 meters, chest figure – 500 meters, belt figure – 600 meters, running figure – 800 meters. The PSO-1 is designed for firing up to 1,300 meters.
This is true for all sniper rifles. In the distance between the windings of 1.5 m / s is 43 cm. For comparison, the median deviation of the surgeons for 600 m – at a height of 9.4 cm, side 8.8 cm.
A good sniper training allows you to conduct fire even on targets such as helicopters and low-speed aircraft. For example, there is a case of Svd jet attack of the Air Force of El Salvador. This happened on November 12, 1989 near the village of San Miguel. The Cessna A-37B “Dragonfly” aircraft was struck at that time. The aircraft has lost control and crashed. Similarly, the Iraqi militants used to claim the destruction of small reconnaissance UAV RQ-11 Raven by fire.
