The 6.5 LMG concept doesn't depend on a particular projectile material. In fact, the length of 6.5mm projectiles allows more options, unless one is relying on the case capacity of a larger, heavier cartridge like the 7.62 NATO or 7.62x54 Russian to suck up the extreme length of a longer solid projectile, which puts us back to the problem with GPMG's and their bulk/weight currently straining the maneuverability of dismounted infantry soldiers. It also reduces case capacity significantly in the x51 case. moving closer to a Grendel case capacity, so the law of diminishing returns pushes towards the smaller case and a smaller bore diameter anyway.
We already know that a 1.285" long Lapua 144gr will perform better for wind drift and penetration than a stubby M80 ball round, with significantly less muzzle velocity starting into the race. At distance, the 7.62 will lose all day long, with more recoil to deal with, and a much heavier gun.
I'm not under the illusion that logical weapons are the ones to get chosen, but I'm not going to push for a polished turd like the M9, SAW, M16A2, etc. I have a conscience and a gag-reflex.
