Indians For Guns

(a) Bolt action or semi-automatic rifles of either .303 (British) or 7.62 mm (NATO) (i.e. 7.62x51mm) bore of any other bore which can chamber and fire service ammunition of .303 or 7.62 mm calibre; Since the 7.62 NATO round is almost identical to the .308 Winchester round, that would necessarily mean that the latter is also classified as a prohibited bore (even though the nomenclature is different). However I may add here that some (older) rifles chambered for .308 CANNOT safely fire 7.62 NATO service ammunition, due to the higher pressures produced by the latter.

As far as I know, .308 Win is not a restricted calibre. 7.62X51 is. There are a couple of differences between the two in terms of case thickness and chamber pressure. The .308 operates at a slightly higher pressure and the 7.62X51 cartridge can be fired in that but not vice versa.

Although not identical, the 7.62×51mm NATO and the commercial .308 Winchester cartridges are similar enough that they can be loaded into rifles chambered for the other round, but the Winchester .308 cartridges are typically loaded to higher pressures than 7.62×51mm NATO service cartridges.[4] Even though the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) does not consider it unsafe to fire the commercial round in weapons chambered for the NATO round, there is significant discussion[5][6][7] about compatible chamber and muzzle pressures between the two cartridges based on powder loads and wall thicknesses of the military compared to commercial rounds.

Hi All ,

Any idea if 308 Winchester is NPB in India ? And how is availability of 308 Win ammo in India .
