Development

It was developed in conjunction with the SIG SG 550 rifle, as a potential successor to the 7.5×55mm Schmidt–Rubin cartridge.[1]

Description

The rimless cartridge has a base diameter of 11.82 mm (similar to the 7.62×51mm NATO) and a case length of 47.72 mm.[2]

The bullet is an unusual 6.65 mm diameter (6.45mm refers to the bore diameter), fractionally smaller than the common 6.5 mm (bore diameter) bullet.

The 97 gr (6.3 g) bullet was fired at a muzzle velocity of 900 m/s (3,000 ft/s) with 2,550 J (1,880 ft⋅lb) of muzzle energy.

Production

The cartridge was not adopted, the SIG SG-550 went into production with the 5.6×45mm GP 90 round.
