New Army "Caliber Configuration Study"

[Tony Williams]

I would love to see a .338MG, but have my doubts it would be a 'medium' machine gun.

The problem is not so much the gun but the weight of ammo. 7.62x51 MG ammo is already considered undesirably heavy for man-packing, but .338 ammo weighs about twice as much. That's the main reason why any MG in this class is highly unlikely to be routinely carried on foot patrol, but will be held back in the fire support role, to be brought out when really needed.
