    This is good review for me and perhaps for others here.
    Video with federal ammo experts and wound cavities. And pistols are pistols and rifles are rifles is how it goes.



    2200 fps is a critical point at which the temporary cavity and permanent wound cavity are about the same. Look what happens when one drastically reduces the length of a 5.56 barrel and velocity decreases.
