8.6 Blackout?

Looks really promising. 8.6 Blackout. They are claiming sub-3" subsonic groups at 300 yards with a 300+ grain projectile

I'd be interested to see the ballistic curve out to 300 yards. With that weight projectile and being subsonic, I feel like that's gotta be like an artillery shell (well, not literally, but you know what I mean ). The 1:3 twist is pretty crazy as well.

Another recent thread on this new cartridge.

I'm assuming this 8.6 Blackout is for the AR 10? It shows the new cartridge next to a 300 BLK, no way will that fit an AR-15 magazine .
I've had a 300BLK for ten years, really like its versatility.

Yes AR10/Bolt Gun.
