>Caliber doesn't change accuracy to begin with
Yeah it does. Whether you mean that in the literal sense of bullet dimensions, or in the general sense of different types of bullet, it matters a lot. It affects bullet weight and ballistic coefficient, which have an effect on resistance to wind and how the bullet deals with passing the transonic range.
>6.8mm is just as good at range as .338NM
No it isn't. 338NM starts with and retains much more energy and penetrative power over range. It's effective range is 1700m, while 6.8mm is effective to 800m, which is less than half the distance.
>MMGs aren't portable
The existing .338NM MMGs are lighter than the m240. The SIG Sauer MG 338 weighs 9.7 kg while the M240L (the lightest version of the M240) weighs weighs 10.1 kg.
It looks like MMGs are seriously useful in certain situations. They have the range of a 50cal while being man portable. They can deal with light armor and penetrate significantly more cover than 7.62x51mm GPMGs. You might think the ammo being heavier is a drawback, but not being able to hit the target if they're too far away is a bigger drawback. Gunners don't carry all their own ammo, anyway.
