In terms of energy 300BLK and 6.8 are very similar, but the 300BLK has the advantages of a better subsonic load, large bullets, full-capacity in standard AR magazines, standard 5.56 AR bolt, etc...

Ammo pricing and availability will be key. I agree.

you just made me a very happy man, 300 ACC blackout it is.
