U.S. Army Seriously Considering the Adoption of a 6.8mm cartridge

The 20% reduction in ammo weight is quite modest and allows room for polymer/metal (or stainless/aluminium) cased versions of conventional rounds. The all-polymer CT rounds exceed 30% saving.

Recent discussions here at Lake City and at PM-MAS Picatinny indicate that the 6.8 cartridge will be made at Lake City - whatever it ends up being on the case.

Money is moving and plans are being made. Current rumors are that it will have its own new building.


Tony, the singing and dancing is fine, but we don’t do tea here, we drink manly-strong coffee.

Ground breaking on new 6.8 building is happening pretty quickly…

In the past, PCP ammo preformed poorly in Light MGs like the SAW, particularly ones with fluted chambers. I understood it was heat buildup compromising the case.

Apparently they have that problem fixed.
