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).
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 uses the 7.62×54mmR Eastern Bloc standard cartridge that produces significantly more bolt thrust when compared to the Eastern Bloc 7.62×39mm and 5.45×39mm intermediate cartridges. With the use of a single spare parts kit and two barrel assemblies the service life of the modernized PKM machine gun series is guaranteed for at least ...
I do have to mention, however, that the .303 British cartridge is older than the 7.62x54R cartridge; it dates from 1889 and is still in service use today in India. I'd be happy to have something like "Historically referred to as 7.62mm Russian[cite], the "R" in the modern designation stands for Rimmed[cite]." Covers both bases, acknowledges the ...
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.

As you dive into your New Year’s resolutions, taking precautions to protect yourself from a quartet of infectious diseases can lessen your odds of starting off 2025 sick.
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]
