The PSO-1 pattern range-finding reticle. The bottom-left corner can be used to determine the distance from a 1.7 m tall target A 1.7 m tall person correctly ranged at 400 metres (437 yd) The PSO-1 features a reticle with "floating" elements designed for use in range estimation and bullet drop and drift compensation (see external ballistics).
Usage has been greatest from military snipers and long-range target shooters, including F-class and benchrest competitors, but hunters have also benefited. Most VLD bullets are used in rifles. VLD bullets typically have a ballistic coefficient greater than 0.5, although the threshold is undefined. [1]
The sandbags provide all the support. By allowing the rifle to move freely backward, the shooter hopes that the movement under recoil will be as consistent as possible. A few short-range rifles and long-range rifles with heavy recoil must be firmly held, even though the aiming is still done with the positioning of the rests.
Velocities for modern varmint rounds are usually in excess of 3,000 ft/s (910 m/s) such as the .223 Remington and some like the .220 Swift can exceed 4,000 ft/s (1,200 m/s). This allows long range shots with a short time of flight, and little change in trajectory at different ranges (see external ballistics). A bullet drop of only a couple of ...
The optic has two standard reticles: both are a cross, feature a range finder out to 600 m (656 yd) for 5.56x45 and 800 m (875 yd) for 7.62x51, where they differ is in the bulletdrop design, where the one called CX5395/CX5396 uses circles to denote the range, while the other called CX5455/CX5456 uses lines and also features lines for windage.
The International Confederation of Fullbore Rifle Associations (ICFRA) is the international association for the fullbore rifle shooting sports of target rifle ('TR') (called 'Palma' rifle in the US) and F-Class, which are long range competitions shot at distances between 300 and 900 meters or 300 to 1,000 yards depending on the range.

The PSRL-1 is typically equipped with a proprietary 3.5× optical sight with an illuminated etched reticle, or an EOTech sight with a holographic reticle. The manufacturer claims a 90% hit probability at 800 meters (2,600 ft) with the standard magnified sight, although it is reportedly accurate at ranges from 900–1,200 m (3,000–3,900 ft).
