I too have looked into the 6.8SPC and wondered why the 6.5 Grendel didn't win that contest. Both of these 6's give more energy at shorter ranges and the 6.5 gives a lot better terminal ballistics at ranges over 500 yards.
Both of these cartridges detriment was making ammo heavier, or the lack of use is probably the same reason why our military isn't using dragon skin armour.
Politics.
I have looked at the 300 Whisper and can't justify its existance over the 7.62x39. With C-Products making reliable mags, it makes for cheap practice ammo, a higher velocity than the 300 Whisper and it too can be loaded down to sub-sonic velocities as well.
My personal choice was the 6x45. Again just a barrelswap.
6mm projectiles from 40 to 107grains and velocities higher than the same bullet weight in the parent 223 cartridge.
For longer range work I chose the 243WSSM.
What is everyone elses thoughts?
