6.8 Mm Cartridges - Developed in collaboration with General Dynamics Ordnance and Tactical Systems and Beretta Defense Technologies, the new polymer cartridge was selected for the US Army's Next Generation Squad Weapon (NGSW) upgrade program. Among the benefits, reduced weight and better accuracy.
True Velocity released the 6.8mm composite cartridge as part of the NGSW weapon system in collaboration with General Dynamics-OTS and Beretta Defense Technologies.
6.8 Mm Cartridges
From compound gun manufacturer True Velocity, here's an interesting look at a new compound gun being evaluated by the US Army for the Next Generation Squad Weapons (NGSW) program. The NGSW program requires the selection of new 6.8mm weapons to replace the team's M249 weapons and M4 machine guns beginning in 2022-2023. A few days ago we talked about new developments, showing you the models produced by SIG Sauer, one of the three companies selected by the US Army to advance the sector after the test. The other two companies are AAI Corporation Textron Systems and General Dynamics-OTS Inc. In a press release, True Velocity informs us that the company's compound gun has been selected for the US Army's Next Generation Squad Weapon (NGSW) upgrade program, adding some exciting images of the upcoming guns. .

” – and the fact that Beretta has also joined the NGSW program is an exciting story in itself.
"Polymer cartridges" weigh less than traditional brass cartridges, are resistant to corrosion, and offer significant logistical and operational advantages. Also,

"Combining True Velocity's innovation and technology with the expertise of General Dynamics OTS and Beretta will result in a weapon system solution that exceeds NGSW requirements and gives the U.S. Army the advantage to the battlefield."
For the carts presented by True Speed, it is worth noting the special design of the neck and shoulder - a well-known weak point, especially in compact cases - which are shorter and less compared to volcanoes handed down. The earlier designs were different, only presenting the neck and shoulders in a brass case (see photo above).
Interestingly, if the US Army were to adopt polymer-based cartridges, it would be the first major breakthrough in military firearms since the introduction of metal cartridges more than a century and a half ago. .

It is in between the 5.56 × 45mm NATO and the 7.62 × 51mm NATO in bore diameter. The bullet has the same diameter (but not the same mass) as the Winchester .270 hunting cartridge.
The 6.8mm SPC cartridge was developed to address the shortcomings of the 5.56x45mm NATO ballistic cartridge in service with the military forces of all NATO-affiliated countries.
The cartridge is the product of the Rifle Cartridge Improvement Program. The 6.8 SPC (6.8×43mm) was originally developed by Master Sergeant Steve Holland and Chris Murray, a US Army Rifleman.
They offer more lethality than the 5.56 NATO/.223 Remington in an M16-model rifle with less loss of magazine capacity and less recoil.

The project began with a design using the .30 Remington case, modified in lgth to fit the magazine that would accommodate the magazines of the M16 family of rifles and cartridges currently in service and the US Armed Forces.
In tests comparing different bullet types using the .30 Remington case, Holland and Murray determined that the 6.5 mm bullet had the highest accuracy and penetration, and previous data returned from decades out of the US Army and ultimate ballistics tests, but a 7 .mm is a better program. The combination of cartridge, powder, and projectile was significantly improved over the Soviet 7.62×39mm and 5.45×39mm cartridges, and the muzzle velocity of the new cartridge was 61 m/s (200 ft /s) faster than 7.62 x . 39.
The 6.8mm Remington SPC was designed to perform better in short range CQB rifles after performance dropped from the 5.56 NATO when the M16A4 was converted from a rifle configuration to the Currt M4 carbine. The 6.8 SPC delivers 44% more power than the 5.56mm NATO (M4 configuration) at 100-300 m (330-980 ft). The 6.8mm SPC is not identical to the balls of the 7.62×51mm NATO cartridge, but it has less recoil, is said to be more maneuverable in rapid fire, and is lighter, allowing it to managers to carry more ammunition than possible. larger caliber round. 6.8 mm increase for 2,385 J (1,759 ft⋅lbf) of muzzle pressure with a 7.5-gram (115 gr) bullet. For comparison, the 5.56×45mm round (the 6.8 was designed to replace it) would have approximately 1,796 J (1,325 ft⋅lbf) and a 4.0 g (62 g) bullet, giving the 6.8 mm the advantage of the circle. 5.56 mm at 588 J (434 ft⋅lbf). One of the main features of this cartridge is that it is designed for the carbine rifle with a barrel shorter than the standard lgth of the rifle (usually 41 cm (16 in). The round only takes 7.6– 10.7 m/s (25–35 ft/s) for every 25 mm of barrel length over a standard 410 mm (16 in) barrel (all the same) up to a barrel length of approx. 560–610. mm (22–24 in) with no gain or loss in accuracy. It also works well in rifles with barrels shorter than 410 mm (16 in). direct development (period 2008–2012) increased the performance of the 6.8 SPC by approximately 61 to 91 m/s (200 to 300 ft/s) thanks to the work of the ammunition manufacturer Silver State Armory LLC ( SSA) and others. Used rifle manufacturers with the correct chamber design and barrel specifications. The weight of a Remington SPC 6.8mm cartridge, depending on the manufacturer and load, is between 16.8 and 17.6 grams. (259 and 272 gr). Also, more precisely, LWRC, Magpul and Alliant Techsystems (AT K) introduced a new AR-15 designed for the 6.8 SPC that accepts 6.8 Magpul P-mags and a full 5.9 cm (2.32 in) cartridge case. The personal defense weapon (PDW) known as the "Ono8" is SPC II w 1:250 mm (10 in) thread and is capable of using all SPC 6.8 factory bullets.
