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).
The below table gives a list of firearms that can fire the 7.62×54mmR cartridge. The cartridge was originally developed for the Mosin–Nagant rifle and introduced in 1891 by the Russian Empire. It was the service cartridge of the late Tsarist era and throughout the Soviet period to the present-day Russia and other countries as well.
In 1975 the twist rate was increased to the standard 240 mm (1:9.4 in), which reduced the precision with the 7N1 sniper cartridge by 19% but allowed for the use of standard "light" ball steel core LPS Gzh (57-N-323S), as well as its variations (incendiary, tracer, armour-piercing) with acceptable precision.

The PK general-purpose machine gun U-shaped receiver is stamped from a smooth 1.5 mm (0.06 in) sheet of steel that is supported extensively by pins and rivets. For additional rigidity and strength the PK receiver features double walls made from 1.5 mm steel plates that are welded together with the U-shaped stamping.
Bullet diameter (G1): 7.85 mm (54R: 7.92) The Finnish commercial ammunition manufacturer Lapua does not make a difference between the 53R and 54R, but produces cartridges that will function in weapons chambered for either one. The Russian ammunition maker Barnaul states that Russian cartridges marked 7.62×53 are the same as 7.62×54.
The PKP Pecheneg (Pulemyot Kalashnikova Pekhotny "Pecheneg", Russian: Печенег) [8] [9] is a Russian 7.62×54mmR general-purpose machine gun. [4] It is a further development and modification of the PK machine gun (PKM). [10]
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is ...
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
