12.7x99 SR SOLID TRACER SX

45.8 g / 708 gr

The 12.7 SR Solid Tracer SX is a lead-free training and tactical cartridge for military users. The lead-free bullet made of turned brass has a special bullet geometry that greatly increases the air resistance in flight. The pyrotechnic charge has a dark ignition tracer that conceals the shooter’s position. The visible tracer begins at a range of 0 m to 200 m and illuminates up to a distance of at least 1,000 m, reducing the danger zone and the maximum flight range to 4.0 km. It is fully compatible with heavy machine guns of the FN Bowning M2 type.
