I have to agree that the .308 simply has way more retained energy on target, unless we start talking about some of the heavier 6.5 projectiles past 500yds, like the 140gr VLD's and 144gr FMJ. The .308 also has a lot more recoil than the Grendel, but their trajectories are very similar.
I think the "extended range .30-30" is an appropriate layman's explanation of the Grendel, since we have similar case capacities. An "extended range 7.62x39" would be even more descriptive. I have owned 3 different .308 AR10's, and I have no plans to ever build one again, I can say that. I do have a .260 Rem AR10 that I love, but I ain't humpin it all over the place anytime soon, which is where the Grendel comes in.
My next build will most likely be an 18" or 20" Grendel with a totally different enlarged bolt and barrel extension, so I can ignore the limitations of the AR15 bolt size, and hot-rod the Grendel to push 100fps faster across the projectile weights. I already know the case can take it.
