Military adopted a new AP Round...It kind of looks like an SS109 with the copper jacket removed. Crusing around online I found a cross section picturce of the new M855A1 and it appears the Steel Pin extends almost to the base. With all that extra weight, I wonder if it's going to be heavier than 77 grains, and what the military will do for M4 Barrels... 1-7 Twist?
