Someone has studied it.  I'm curious, the great thing about the 5.56 is is that, upon impact, it is suppose to fragment, although this fragmentation doesn't occur below 2,800 fps.  Why would our military be using a heavier grain bullet?  It would have a lesser velocity, so it wouldn't fragment as far away, since the heavier bullet would lose velocity quicker.  

Could someone who has studied this provide input?

Thanks.

Heavier bullets fragment more reliably and at lower velocities.

75 grain ammo fragments down as low as 2200 fps... longer bullet and thinner jacket means more stress during yaw with less jacket to hold it together.

It yaws and fragments much more quickly upon entering tissue. It fragmetns to a greater degree, causing more tissue damage and fragments more reliably. It is twice as accurate.
