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 LPS 4×6° TIP2 elevation turret features bullet drop compensation (BDC) in 50 m increments for engaging point and area targets at ranges from 100 m up to 1,000 m. The BDC feature must be tuned at the factory for the particular ballistic trajectory of a particular combination of rifle and cartridge at a predefined air density.
