The 6.8 is the way to go, and it’s battle tested.
For a rifle that size, you cant beat it for sheer knockdown and stomp em power.

Sure you can, with a 6.5 Grendel. At least with the Grendel you can hit out well past 300 yards - out to 800+ no problem. If you need extra short-range performance, you can use a lighter bullet - but the 120 gr. bullets provide an excellent balance.
If a 62 gr. 5.56 bullet was even close to sufficient, a 120 gr. 6.5 bullet is plenty. If you want to see the terminal effects, take a look at the JFK shooting video - that’s about right (that was with FMJ military ammo, slightly heavier bullet at lower velocity).
The 123 gr. Scenar from the Grendel exceeds the ballistics of the 147 gr. 7.62 ball round by a good bit - out of a lightweight AR platform.
