The 7.62×54mmR is a rimmed rifle cartridge developed by the Russian Empire and was introduced as a service cartridge in 1891. Originally designed for the bolt-action Mosin–Nagant rifle, it was used during the late Tsarist era and throughout the Soviet period to the present day. The cartridge remains one of the few standard issue rimmed cartridges still in military use and has the longest service life of all military issued cartridges in the world.
The American Winchester Model 1895 was also chambered for this cartridge per a contract with the Russian government. The 7.62×54mmR is still in use by the Russian military in the Dragunov and other sniper rifles, as well as some modern machine guns like the PKM. Originally, the round was designated as "Трехлинейный патрон образца 1891 года" - (Three-line cartridge model of 1891). It then became widely known under the designation "7,62мм винтовочный патрон" (7,62mm rifle cartridge). The round has erroneously come to be known as the "7.62mm Russian" (and is still often referred to as such colloquially), but, according to standards, the "R" in designation (7.62 × 54 R) stands for Rimmed, in line with standard C.I.P. designations. The name is sometimes confused with the "7.62 Soviet" round, which refers to the 7.62×39mm cartridge used in the SKS and AK-based (AK-47) rifles.

The 7.62×54mmR is the oldest cartridge still in regular combat service with several major armed forces in the world. In 2011 the cartridge reached 120 years in service. The 7.62×54mmR is currently (December 2013) mainly used in sniper rifles like the Dragunov sniper rifle and machine guns like the PKM. The .30-06 Springfield cartridge (7.62×63 mm) with its higher service pressure and case capacity can outperform the 7.62×54mmR, especially when same length test barrels are used in this comparison. The 7.62×54mmR's case capacity prevents it from reaching the most powerful .30-06 loads, but even with this limit, it has been used to successfully kill large bears. Because of performance similar to the iconic American .30-06 cartridge, a similarly rich military and historic heritage and amazing longevity, the 7.62×54mmR is nicknamed "the Russian .30-06" by some. It is also one of the few (along with the .22 Hornet, .30-30 Winchester and .303 British) bottlenecked, rimmed centerfire rifle cartridges still in common use today. Most of the bottleneck rimmed cartridges of the late 1880s and 1890s fell into disuse by the end of the First World War.
The 7.62×54mmR originally had a 13.7 g (210 grain) "Jager" round-nosed full metal jacket (FMJ) bullet. Due to experiences in the Russo-Japanese War, the projectile was replaced in 1908 by the "L" 9.5 grams (147 gr) spitzer bullet, which basic design has remained standard to the present.
To increase accuracy for the Dragunov SVD, the Soviets developed the 7N1 variant of the cartridge in 1966. The 7N1 was developed by V. M. Sabelnikov, P. P. Sazonov and V. M. Dvorianinov. It used match-grade extruded powder instead of the coarser ball propellant and had a 9.8 g (151.2 gr) boat-tailed FMJ jacketed projectile with an air pocket, a steel core and a lead knocker in the base for maximum terminal effect. Produced by “Factory 188” (Novosibirsk Low Voltage Equipment Plant), cartridges are only head-stamped with the number “188” and the year of manufacture. It came packaged 20 loose rounds to a paper packet, 22 packets to a metal “spam” tin, and two tins per wooden case for a total of 880 rounds. The individual paper packets, hermetically sealed metal 'spam' cans, and wooden shipping crates were all distinctly marked Snaiperskie ("Sniper") in Cyrillic. Even the wax wrapping paper for the paper boxes was covered in red text to make sure it wasn't misused.
As hard body armor saw increasing use in militaries the 7N1 was replaced in 1999 by the 7N14 special load developed for the SVD. The 7N14 round is loaded with a 9.8 g (151.2 gr) projectile containing a sharp hardened steel penetrator to improve penetration which is fired with an average muzzle velocity of 830 m/s (2,723 ft/s).
The 7.62×54mmR has 4.16 ml (64 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under challenging conditions. The cartridge's shape remains the same to the present day.
7.62×54mmR maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm).
Americans would define the shoulder angle at alpha/2 ≈ 18.5 degrees. The common rifling twist rate for this cartridge is 240 mm (1 in 9.45 in), 4 grooves, Ø lands = 7.62 mm (0.300 in), Ø grooves = 7.92 mm (0.312 in), land width = 3.81 mm and the primer type is Berdan or very rarely Boxer (in large rifle size).
According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the 7.62×54mmR can handle up to 390.00 MPa (56,565 psi) Pmax piezo pressure. In C.I.P. regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to consumers. This means that .303 British chambered arms in C.I.P. regulated countries are currently (2014) proof tested at 487.50 MPa (70,706 psi) PE piezo pressure.
The attainable muzzle velocities and muzzle energies of the 7.62×54mmR are comparable with the 30-06 U.S. military cartridge. The spitzer bullets used in the military variants have a particularly elongated shape which results in a favorable ballistic coefficient and sectional density, contributing to an adequate long range performance and energy retention.
When used with modern hunting bullets, the 7.62×54mmR is capable of taking game in the medium to large sized class (CXP2 and CXP3). The 7.62×54mmR can offer very good penetrating ability due to a fast twist rate that enables it to fire long, heavy bullets with a high sectional density. In Russia, the 7.62×54mmR is commonly used for hunting purposes mostly in sporterized Mosin–Nagant rifles and civil Dragunov variants (Tigers).
Basic Specifications of 21st Century Russian Service Loads
The 7.62×54mmR rounds in use with the Russian Armed Forces are designed for machine guns and sniper rifles. As of 2003 there were several variants of 7.62×54mmR rounds produced for various purposes. All use clad metal as case material.
- A conventional steel-core bullet designed to engage personnel and weapon systems. The bullet has a steel core. The tip has no distinguishing colour. It can penetrate a 6 mm (0.2 in) thick St3 steel plate at 520 m (569 yd) and 6Zh85T body armor at 110 m (120 yd).
- An enhanced-penetration bullet designed to kill personnel wearing body armor, featuring a heat-strengthened core. The tip is uncoloured. A sealing lacquer belt on the mouth of the case is red-coloured. It can penetrate a 6 mm (0.2 in) thick St3 steel plate at 660 m (722 yd) and 6Zh85T body armor at 800 m (875 yd).
- Variant of the T-46, a tracer bullet designed for fire adjustment and target designation. The bullet has a green tip and the tracer burns for 3 seconds.
- Variant of the B-32, an armor-piercing/incendiary bullet designed to defeat lightly-armored targets. The bullet has a black-red tip.
- A sniper round designed for improved accuracy. The tip of the bullet is uncoloured.

7.62×54mmR is widely available both as military surplus and new production, but less so for match-grade rounds. Most surplus ammunition is steel-cased and uses Berdan primers, which effectively hinders its use for handloading. However, with the increased popularity of surplus Eastern-bloc Mosin–Nagant, SVT-40, and PSL rifles in the United States, Boxer primed ammunition and unfired cases are increasingly available; these cases take large rifle primers.
The 6.5×54mmR cartridge used in many Vostok brand target rifles in the 1960s and 1970s is a necked down version of the 7.62×54R.
