"Remington 6.8 SPC"
The 6.8mm Remington SPC (Special Purpose Cartridge).
Remington developed this cartridge for evaluation by the
Armed Services in response to a duty request for a cartridge
with a terminal energy more nearly like  the 7.62x51 (.308)
while retaining the low recoil of the 5.56x45 (.223).
The Remington design is based on shortening the base case
of the semi-auto .25, .30, .32 Remington series and necking it
to accept  6.8mm (.270) projectiles.
I have been told that it was being tested in Afghanistan ?
