Seems the Army has finally figured out the 5.56mm needs some rework: New Army Ammo Puts Mean in
They've taken a page from the 5.7 X 28 on pentration. As a Viet Nam Vet the 5.56mm was never on my list of perferred rounds!:aargh4:
These rounds don't improve it much and it is still an inferior round to the 7.62 either Nato or Russian.
