6.8 is the new standard?

I read an article that the US Army has decided that 6.8 will be the new caliber of choice for M4/SAW replacement.

What will NATO do?

I hadn't heard that one yet, but the fight for 6.8 has been going on for over a decade. If it happens, NATO will follow suit but probably a few years behind. How else will they continue to get free ammo?

it's on the FBO site
https://www.fbo.gov/index.php?s=oppo...tabmode=list&=

“NGSW-R” refers to a prototype 6.8 millimeter rifle with sling, flash hider, suppressor, cleaning
kit, flash hider/suppressor removal tool, and quantities of magazines required to provide a
minimum of 210 stowed rounds.
“NGSW-AR” refers to a prototype 6.8 millimeter automatic rifle with bi-pod, sling, flash hider,
suppressor, cleaning kit, flash hider/suppressor removal tool, and quantities of
magazines/drums/belts/other required to provide a minimum of 210 stowed rounds.

Maybe focus on markmanship and a heavier 5.56 bullet? Between the two branches I served in, the Navy had a better markmanship program. In the NMCB we shot the USMC way. I went in the Guard and found the markmanship training lacking. Same with being mobilized for OIF best shooters in my unit were all former USMC or Navy.
Training not new gear IMHO.

I agree with Sharky, if we change over NATO will follow.

Wonder what the weight difference of the rounds are? 6.8 will be heavier, but by how much?

They're using 6.8 PROJECTILES as the USG provided material for the next generation of ammunition, which is intended to be caseless, case telescoping, polymer or something like that.

I do not see a move away from conventional brass cased 5.56x45 at this time. Not when we just adopted M855A1, which seems to be good ammo. I'm glad I was wrong about that one. S/F....Ken M

Well the 5.56 EPR rounds I've shot at the range sucked. You could be getting a nice grouping than you'd get a flyer way out in left field. So doesn't matter what caliber we shoot if the quality control sucks.

Ken: It notes: Primed Case. Primed Case (case and primer) ammunition shall be provided
However the Attachment is missing for the ammo specs.

The way I'm reading it, "each Offeror developing two weapon variants and a common cartridge for both weapons, utilizing Government provided 6.8 millimeter projectiles."

In the Statement of Work, it outlines the deliverables:
Quote:
The Contractor shall develop a common cartridge that can be fired from the NGSW-R and NGSW-AR. Design consideration data is provided in Attachment 3 – Ammunition Data. The Contractor will LAP the common cartridge with the following Government provided projectiles to support Government testing:
I maintain that this is for development of CTA, caseless or other unconventional ammunition. S/F....Ken M

I have a POF in 6.8. Uber accurate. My business partner and his crew all sold their 5.556 rifles and now shoot 6.8's.

Green tip = 184.3 grains
SSA 110 BTHP = 266.9 grains

Do you see advantages of 6.8 over 5.56 for troops?
On paper is one thing in the field is another. How do you like it? I know it has a folowing with hunters.

Is the case made from a reformed 5.56 case, like .300 Blackout is?

6.8SPC is a unique case, based on the old 30 Rem or something like that. It's got more capacity than 5.56. It's what the "new" 224 Valkyrie and 22 Nosler are based on. S/F...Ken M

Is this a different kind of measurement that you're using? I looked around and it says SSA 110 BTHP is a 110 grains.

I wouldn't hold my breath waiting to see if they change to 6.8.

How much more capability would it bring and at what price point? Maybe someone sees the ROI, but I'm scratching my head.

Guessing he's talking about the weight of the loaded round, not the projectile- the kind of thing a guy who had to carry a battle load-out might be concerned with.

Greaaaat!

Now I'm gonna have to listen at the American Legion from all the "old guys" who's gonna remember how great the M4/M16 was compared to the new mattel 6.8. Kind of like the M14 guys or the Garand guys.

Aww, nuts.

No that's the weight of the entire cartridge; brass, powder primer and projectile as it stands in the picture.

No, the entire case is wider. The size proportion is the length, its the same as the 5.56, but it takes a different follower. The projectile is merely a .270 projectile at .277"
