[QUOTE="Catfur, post: 858090, member: 41271"] 5.56 FMJs do more damage than larger FMJs (to a point) at just about any reasonable distance (repeated tests have shown this, even as far back as the 6mm Lee Navy days). UNLESS you spin them up (stabilize them) at ungodly RPMs by firing them out of a fast twist barrel. At an appropriate twist rate of something like 1-14 or 1-15, a 5.56 FMJ round will tumble wildly in flesh. At 1-7, it will just pencil through most of the time. Of course, Uncle Sam spins those little babies up to twice the RPMs they need to stabilize them, and then doesn't listen when the troops crab about them not doing any damage. Back in the Vietnam days, the M16 prototypes gained a reputation as unholy killing machines. Later hindsight showed that the first prototypes (provided to special forces) were 1-17 to 1-20 twist barrels, because Armalite was unable to produce the specified twist rate, and they were basically firing bullets that tumbled straight out of the barrel. Of course at the ranges special forces usually operate, nobody noticed that accuracy over any distance would have been crap. I still say ditch the Hague Conventions (written by a bunch of diplomatic pantywetters) and use expanding bullets when appropriate (IE when armor piercing is not necessary). [/QUOTE]
