New Cartridge Developments and Implications for Dismounted Infantry Soldiers

[stanc]

Intriguing comment on the possibility of the USMC seeking a new intermediate cartridge:

We did have an ulterior motive. There was a pending requirement for a new intermediate caliber. If we could improve the consistency of the terminal effects of our current 5.56mm round and use it as a temporary solution, it would bridge the gap until we could get the requirement going for an intermediate caliber. The intermediate caliber requirement remains in the discussion phase.
