Keep in mind that the military is actively field testing the heavier 75 and 77gr loads (Hornady BTHP and Sierra MK) in Afganistan, and supposedly are quite happy at how those loads are performing, in the real world, against actual people, out of the M4. The heavier, longer, thin jacket bullets seem to be much, much more insensitive to velocity loss than the ball (M855) loads. So perhaps the M4 does have a future after all...
