12.7x99 HC SX

47.5 g / 733 gr

The 12.7x99 HC SX tactical cartridge is designed for military use. It is designed for use with repeater rifles and semi-automatic firearms for precision shooters and snipers. It has a hard core bullet consisting of a hardened steel core with a jacket. This guarantees utterly reliable effectiveness against hard targets. The cartridge can be used without restriction in a temperature range from -54°C to +52°C. It is also sealed against the ingress of water and moisture. The use of components without lead or heavy metals minimises exposure.
