Let me elaborate more as to why velocity plays a significant part in causing damage to flesh. A round moving faster creates more air pressure behind and in front of it this air upon entry into flesh creates a balloon within nano seconds. The smaller the entry wound the more damage affectionately called the suck or the pop within the us military. And a 5.56 is not a 223 round you may safely chamber and fire .223 ammo in a 5.56 chamber but do not attempt to fire 5.56 out of a .223 chamber. And a 223 you may notice starts with the digits .22 because it is in fact .22 caliber pull out some veneers and measure a .22 rim fire and a .223 round they are the same. Just like a 9mm, 38 special and .357 mag are allowed also the same diameter aka caliber. And hydrostatic shock is a myth created to get people to buy ammo or caliber specific firearms. Remember hydro shok ammo lol. Just an old guy who has forgotten more about firearms and ammo than most people know.
