Our military adopting the Grendel?

[montana]

I'm sorry but the 5.56 sucks. I have owned and still do many 5.56 rifles and they are fun to shoot, but any experienced hunter knows how in effective the 5.56 is for terminal performance. For the AR-15 type platform the 6.5 Grendel is the most efficient cartridge to date period. Any cartridge can kill, but to use the most efficient cartridge based on recoil, penetration, weight, ballistics, and cost the 6.5 Grendel is unsurpassed period. Prove me wrong. I'm dug in and waiting.
