Meanwhile, in the US, folks are developing the .300 Blackout.
Two ships passing in the night.
Apt description.
I always thought the 6.8 showed a lot of promise.
The .300 Blackout was developed as an ideal round to fire out of suppressed/short barrel AR platform rifles. Its not intended as a general service cartridge, but it shows promise as a bodyguard/private security, home-defense, and truck-gun cartridge.
