From Herschel Smith: Army And Marine Corps On M855 Ammunition
So in summary, the SOST is much like the .223 pointed soft point for game hunting, except that it has a copper shank. If a reader would like to weigh in on the effects of the copper shank, please do so (in an educated fashion – and do not allow this to become yet another worthless argument over 7.62 v. 5.56). Finally, don’t forget the main reason for the lethality of the 5.56 mm round, which is the fact that it is frangible and immediately fractures into pieces leaving multiple tracks through ballistics gelatin. See the excellent paper Small Caliber Lethality: 5.56 mm Performance In Close Quarters Battle. It appears that the Army has forgotten the simple things.
