U.S. Commandos Want Lighter Machine Gun Ammo
***Warrior Maven Video Above - New F-22 Weapons Breakdown***
U.S. Special Operations Command is looking for ammunition that weighs 40 percent less than current cartridges for machine guns and rapid-fire miniguns.
Having lots of ammunition is good. Carrying lots of ammunition, not so good.
So, U.S. Special Operations Command is looking for ammunition that weighs 40 percent less than current cartridges for machine guns and rapid-fire miniguns.
The goal of the feasibility study is to assess whether it is possible to develop “belt link cartridge cases that are significantly lighter than brass cases and have increased internal volume, pressure ratings, corrosion resistance, long-term storage, and structural integrity,” according to the SOCOM research solicitation.
SOCOM has multiple questions that vendors will need to answer, such as what makes the new ammunition superior to existing cartridges made from brass.
In addition, the cartridges must have a long shelf life. Vendors will have to explain the "materials used in the manufacturing process, the manufacturing method used (i.e., high-temperature welding, friction welding, gluing, etc.). Explain how the materials and the manufacturing methods prevent degradation of ammunition to make it ready for use even while the ammunition is in storage for 10 or more years."
Phase I of the project will involve devising a feasibility study to show it is possible to develop lighter ammunition. The second phase will be to prototype and demonstrate lighter 7.62-millimeter NATO and .338 Norma Magnum rounds.
Other users besides SOCOM would benefit from lighter ammunition. “This system could be used in a broad range of military applications where the weight of small arms ammunition is a critical consideration both for the operator and the logistics system,” SOCOM says. “Lighter weight saves transportation cost for military and commercial ammunition shipments.”

SOCOM has several small arms projects for its marksmen, including adopting the 6.5-millimeter Creedmore round for its sniper rifles. The goal is to double hit probability at 1,000 meters (1,093 yards) versus legacy ammunition, as well as increase effective range 40 percent, reduce wind drift by 30 percent and have less recoil. SOCOM also has its Advanced Sniper Rifle project to replace the multiple models of sniper weapons that currently equip U.S. commandos. A standardized rifle would minimize logistics and maintenance issues.
SOCOM is also exploring a lightweight assault machine gun chambered for 6.5-millimeter ammunition. Other projects include a new upper receiver group for the M4A1 carbine, a suppressed upper receiver group for rifles, more advanced rifle scopes and night vision devices, as well as improved 105-millimeter and 30-millimeter shells for heavier weapons.
