Except of course a mounted GPMG, right?
Make no mistake the 7,62 NATO has it's place, but I think it is senseless to arm every foot soldier with this heavy and recoil intensive weapon. Sure, he can reach out and touch someone beyond 500 meters, but that is what the GPMG and DM is for, right?
The more I look at it, the more I begin to see where the Army is going with this. They want a round that has enough umphf to replace the 7.62 NaTO as a GPMG round, yet light enough recoil and size to replace the 5.56 as an AR round. May just be the "Wonder Cartridge" we needed in VN!
What of the 6.5 Grendel. I've read that it out performs the 6.8 quite a bit.
