Those guns weren't really an issue over there. Compared to a squad with M4s, of course the .311 had more stand-off. Run some 240s against those fukkers, and they'd bug out. Then, give 'em the .50 and the Mk19 from the gun trucks. The M4 with 62gr SS109 has you at some distance limitations, the ammo is 550 meters point-target from a 20" M16A2. Run Mk262 through M4s, and your range increases. Run some Mk12 guns on the deployment with Mk262, and increase your range more. As I've stated - Mk12 can run 850 easy, with light wind. Mk12 can run 850 in a 14.9mph wind, with wind holds that work. Mk12 can run 1050 and it's not that hard in a light-wind condition - all with 75 or 77gr loads. Terminal performance might suck, at those distances, but the dude that has the leak from it won't be coming any closer - and neither will any of his buddies that saw it, or are taking care of him.
