Could the Grendel be used a lightweight sniper rifle?

[LR1955]

is the 6mm arc significantly better than the 6.5 grendel in a sniping role??

Exterior ballistics of my 6 AR is a quantum improvement over any Grendel load. So, hit probabilities would be significantly better.

How much more lethal? Depends on the bullet design. And that will influence external ballistics.

I will say this much, a 6mm anything will burn through barrels much faster than larger diameter rounds until you get to the big magnums.

So, you guys getting high speed 6 ARC barrels are advised to buy two initially and one a year there after. You will be amazed at how fast the throat disappears with one.
