The 12.7x99 SR Solid SX is a lead-free training and duty cartridge for law enforcement and military users. The twisted lead-free brass bullet has a special bullet geometry that greatly increases the air resistance of the bullet in flight. As a result, the danger zone and the maximum flight range can be reduced to 3.8 km. A corresponding weapon function from heavy machine guns of the FN Browning M2 type is guaranteed.
