A medium machine gun (MMG), in modern terms, usually refers to a belt-fed machine gun firing a full-powered rifle cartridge, and is considered "medium" in weight (15–40 lb or 6.8–18.1 kg).

The SIG Sauer MG 338 is a medium machine gun manufactured by the SIG Sauer company. The SIG MG 338 is primarily chambered in .338 Norma Magnum and has an effective range of approximately 1,700 meters, approximately twice the effective range of 7.62x51mm, while at 1,000 meters, it is still capable of penetrating Level III armor.

2024年4月17日 · By 2016, the problematic capability gap between America’s medium and heavy machine guns was well defined and the solution was identified in the form of the 338 Norma Magnum (338 NM) caliber cartridge. The 338 NM cartridge provides triple the ballistic performance of a 7.62 NATO cartridge fired from an M240B.

2024年4月19日 · The SIG-MMG 338 is capable of not only being converted to standard 7.62 x 51mm to align with NATO ammunition and current stockpiles, and it’s specifically designed to handle high-pressure ammunition such as the Army’s new hybrid 6.8 x 51mm NGSW ammunition and is poised for the use of hybrid 338 NM cartridges, should they be adopted.

Develop and deliver the .338 Norma Magnum (NM) brass-cased ammunition for the testing of the next generation Lightweight Medium Machine Gun (LWMMG). The LWMMG will utilize the efficient .338 NM cartridge to eliminate the capability gap that exists between 7.62mm NATO and .50-caliber weapons.

While the M240 has an effective range of 1,100 m, the LWMMG fires a 300 gr (19 g) .338 bullet that can provide effective and accurate fire out to 1,700 m. General Dynamics officials say their machine gun is not meant to be a replacement for the M240, but to give the ability to put effective fire on targets at extended ranges.

In comparison to the current M240 (7.62x51cal) machine gun, which has been in service with the U.S. Military for 60 years, the SIG MG 338, is noticeably lighter, weighing only 20 pounds, and provides significantly more range and lethality.
