Our military adopting the Grendel?

[stanc]

Better than the 7.62X39. Its the same weight but better ballistic coefficient. The 7.62X39 has never been faulted for penetration like the 5.56 has. This isn't a Ford Chev argument its based on reality.The cartridge which has the best fundamentals of weight, terminal performance,recoil, penetration, ballistic performance AKA long range performance and cost should be used. The Grendel has them all.

Do you have terminal effects test data for military ball loadings of 6.5 Grendel?

I have yet to see any, so I'm curious as to how you reached your conclusion.
