The 6.5 Grendel is an interesting round, and I think its a better choice then the 6.8 SPC for M16 type rifles, and would be a better all around caliber choice for military applications. The Grendel does perform better at 1000 then the M118LR or Fed GMM 175gr .308. But, it isn't significantly better, and hits with less energy. I personally kind of like the cartridge and hope to explore it some more, but not until there is more commercial backing in terms of ammo. I'm actually not sold at all on the 6.8 and would rather see the Grendel used. I seriously doubt either one will be adopted universially.... hope I'm wrong.
For sniping/long range work, I still think that a 6.5 with ballistics as good as the .300 Win Mag at 1000 with recoil the same as .308 and in a short action is the ideal. And is what I'm attempting to acheive with the SC2 in .260 or 6.5x284.
