[QUOTE="WildRose, post: 1194986, member: 30902"] The 5.56 was specifically developed for 16-20" barrels and performs very well in them. Again, just like with the .308 there is only a minimal gain in velocity with longer barrels with perhaps one exception which would be in using the heavy for caliber VLD's using slower burning powders than those developed for use in military rifles. Honestly you could probably get better information on both calibers over as Sniper's Hide or Sniper Central for more detailed discussion as you will fine a whole lot more guys shooting both calibers there.
