Pentagon Confirms Move to 6.8mm

To hear the 6.5 guys talk, those cartridges have made the 6.8 superfluous to the point of obsolescence.
Does my heart good to hear the 6.5 bunch whine. They have a high percentage of obnoxious fans that I have never seen for any other cartridge.
 
Lack of recoil? That's not what I saw. I saw distinct signs of the shooter taking the recoil. But no muzzle rise and super lightweight, plus bigger bullet at higher velocity--that's a winning combination.

What interests me is the whole concept of delivery of powder and projectile into a chamber for firing in a capsule, sorta like a return to the old days of musket loading with a modern twist. This removes the brass case tolerance altogether from the pressure rating equation.
 
I liked in the video how the guy kept going on and on about how everything is muscle memory compatible with the SAW and AR platforms, then had to ask how to load the weapon. I am also 100% certain that breakdown and cleaning are going to be very different as well.

The telescoping ammo is interesting. I appreciate the reduced weight, but that does seem to come at the cost of increased bulk.
 
I hate to be the one to drag this one out of the dust pile...

But are there any updates to this. I was pretty adamant that this would fail to become a weapon in widespread use across the Army, but I’ve been wrong before.
 
Does anyone remember the XM8? I'm still betting we're a long ways off from wholesale replacement of the M4 as the primary weapon system in the military. However, like withe the XM8 program the military will incorporate some if tbe new technologies into existing systems. The XM8 program showed how modularity in firearms could work and gave the military a new grenade launcher the M320.
 
All the 6.8 developers were required to use the same bullet. Presumably Mr Litz had a hand in its design. The cartridges are wildly different, he didn't likely have a say in that.

I was talking about the 338 (and the 300) Norma magnums--I believe they were designed from the ground up--including the cartridges--to be superior sniper systems. I lost track of it--but there's a video review someplace of the new weapons.
 
Except for maybe the Mighty 10mm.
You mean the almighty 10mm? I have several of them. I was once hunting with my G20 and spotted a nice buck at about 400 yds in thick cover but I wasn't confident that I could dope the trajectory with just the factory iron sights. I then popped the magazine and removed one of the cartridges, and holding it high above my head I waved it back forth and made a doe bleat at the same time. When the buck saw I was holding a 10mm cartridge, it had a heart attack and fell over dead right there!
 
Interesting,
Says: "The LWMMG weighs 22 pounds, placing it well within the weight class of the 27-pound M240 machine gun"
Lighter weight but more powerful, it is lighter to hump but will kick more.

Should be a clear overmatch to the dragunov--but most impressive is the performance and the cartridges it will replace. Well-timed to a "new crop" of high performance .338 bullets, some of which I've used in my .338 LM.
 
We know that big, heavy bullets are good man-stoppers.

Heck, just ask George Custer!:p
The last war we won, we dictated what small arms would be used based in large part upon their killing capability; not their wounding capability. We called the shots and the world followed.
 
If you're talking about WWII, the U.S. picked their calibers for that war by basically sticking with the calibers they were already using and justified that decision by the logistics savings.

Otherwise the M1 Garand would have been a 10 shot 7mm--which, by the way, would have likely had just about zero impact on the outcome of the war since it was won primarily by superior manpower, massively superior production volume capabilities, air power and ultimately nuclear weapons in the Pacific.
