|It seems that in morden fire arms development espeacially in the area of assault rifles, the focus has mainly been on the rifle itself, lighter weight, greater accuracy, mechanical reliability, red dot + laser optics, new lighter magazines, even highly effective muzzle breaks and compensators that allow u to chop the barrel length of the M16 to ridiculous propotions, yet be able to shoot normally.
But apart from the bullet head and core (And for the 5.56, the verdict is still out on the best bullet type), the closest that anyone has come to really improving on the metal cartride had been the caseless ammunition by Heckler and Koch.
Now the question here is how does the weight of American smokeless gun powder compare to that of the weight used by the Russians since 1947 for their ruskie rounds????
Can the United States develop a 7.62 X 57mm cartridge that is the same weight or lighter than the 5.56 round???? Using polymer plastic casings, kevlar or some new materials that need not be reloadable????
The rifles have improved, why not the bullets??? Does everyone believe that just because a round is standard and used universally it is good?
