The other elephant in the room is that they'll be moving from a 6-pound rifle to a 9-pound rifle, more, of course, with the high-tech optics the military has become so fond of (and for reason). That's difficult to avoid if you're after terminal energy with reasonable recoil. But that's three (or whatever it actually turns out to be) more pounds of rifle that translates to three less pounds of other gear.
As a side note, I wish commentators would lose the silly affectation of worrying about a battle rifle penetrating too much drywall to keep the babies in the next room safe. This thing was designed to penetrate level 4 body armor at range, f'Petessake. Give it up.
We can’t all run around with 50 caliber in our cars and trucks................yet....................
Isn’t bullet velocity the culprit in barrel degradation? I see a listed muzzle velocity of 2830 fps. That’s not excessive.
