The maximum radius was now attained at some 15.95mm from the tip and the overall length of the bullet increased to 26.8mm. To preserve the total length of the cartridge, the case sleeve was shortened to 38.7mm (and by rounding it is customarily referred to as 7.62×39.) Additionally, the new bullet had a core made of lead wrapped in low-carbon ...

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.

The .308 Winchester is measured across the grooves and uses a .308-in diameter (7.82-mm) bullet; the military-specification version is known as 7.62 × 51 mm NATO, so called because the bore diameter measured between the lands is 7.62 mm, and the cartridge has a case 51 mm long.
Winchester branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester. The dimensions of .308 Winchester are almost the same as 7.62×51mm NATO.
