The DM91A1 is a lead-free and low-emission load that is engineered for military users. The bullet is based on a steel core, which is completely encased in a tombac jacket. The sheath itself is also tin-plated. The cartridge is intended for use in heavy machine guns such as the Browning M2 and M3. It describes the same trajectory as the 12.7x99 LF Tracer SX, which is also available.
