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.
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.
The below table gives a list of firearms that can fire the 7.62×51mm NATO cartridge. This ammunition was developed following World War II as part of the NATO small arms standardization, it is made to replicate the ballistics of a pre-WWII full power rifle cartridge in a more compact package.
The 7.62 mm designation refers to the internal diameter of the barrel at the lands (the raised helical ridges in rifled gun barrels). The actual bullet caliber is often 7.82 mm (0.308 in), although Soviet weapons commonly use a 7.91 mm (0.311 in) bullet, as do older British (.303 British) and Japanese (7.7×58mm Arisaka) cartridges.
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 first AC-130A Gunship IIs did away with the MXU-470/A mounts and instead used GAU-2/As, and not only had four 7.62mm GAU-2/A minigun mounts, but added four 20mm M61 Vulcan 6-barrel rotary cannons; this configuration was upgraded two years later in 1969 by removing two each of the GAU-2/As and M61s and adding two 40mm (1.58 in) L/60 Bofors ...
The C.I.P. lists the projectile diameter as 7.83 mm (.311–.312 caliber), which is the same bullet diameter as the British .303 British cartridges and Soviet ".30 caliber" rounds like 7.62×39mm. .308 Winchester(7.62 mm)-size bullets are safe and usable but would not necessarily be the most accurate. Reloading in this chambering is a nuisance ...
