You guys also have not seen the M855A1 rounds now deployed standard to Afghanistan, they outperform a standard 7.62 but in a 5.56 config, they do not have any lead but use a copper jacket instead and the accuracy and stopping power are greatly increased in this armour piercing round.This round ships with intent on use in standard issue rifles such as the current m16 and m4.and yes the round is standard issue not some special thing so id bet this will cut thru a typical vest like warm butter

agreed, this as well as penetration of armour and mapping the kill areas on the body center of mass should be very high in priority

Cute pic, Totaly agree
