The 5.56 in hollow point, ballistic tip and soft point is far more effective than fmj. FMJ relies on either less than 100 meters (still not stabilized on its axis) or striking a bone to cause a large amount of damage. Velocity is very important for such a small diameter. The trend for shorter barrels has hurt the round significantly as the rated spec of 3200 fps is for a 20" barrel. The M4 has a 14.5" and is commonly issued. That 5.5" results in a significantly reduced velocity that severely reduces the effectiveness of the round, especially at ranges greater than 100 meters. This is mitigated by use of expanding projectiles, however it is banned by the Geneva convention, so it isn't helpful for our military. Law enforcement has no such limitations and that makes the round far more capable. At short ranges, like in the video, 5.56 is quite brutal.
