7.62×54mmR
Russian rimmed rifle cartridge

The 7.62×54mmR is a rimmed rifle cartridge developed by the Russian Empire and 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 one of the longest service lives of any military-issued cartridge.
The fully-powered 7.62×54mmR cartridge is still in use by the Russian military in the Dragunov (SVD), SV-98 and other sniper rifles, as well as some modern general-purpose machine guns like the PKM and Pecheneg machine gun. Originally, the round was designated Трехлинейный патрон образца 1891 года – (three-line cartridge model of 1891). It then became widely known under the designation 7,62мм винтовочный патрон (7.62 mm 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 (7.62×54mmR) 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 rimless 7.62×39mm intermediate cartridge used in the SKS and AK-based (AK-47, RPK) rifles and light machine gun.
Background
The 7.62×54mmR is the second-oldest cartridge still in regular combat service with several major armed forces in the world. It is second to the .303 British which entered military service in 1889 and remains in service, primarily in some noncombatant Commonwealth nations around the world.

Why this record matters
The phrase “russian rimmed rifle cartridge” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q259199. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1891 and 1889.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
