What do you think of the 6.8mm, looks like the Army will switch to it

I've seen a few articles about the new combat rifle. They will replace the 5.56 with the 6.8 in both the M4 carbines and SAW M249. 


It's only true if it's on this forum where opinions are facts and facts are opinions

    As a complete outsider to such things, it sure seems to me that there has been a lot of "wasted motion". First they went smaller, now they're edging in the direction of .30 caliber again with a .27-ish as they've found their engagement distances are longer than what was anticipated with the 5.56.
    Interesting. I assume the 6.8 is already a NATO round?

    No, the NATO round is well the 5.56 NATO.

    Of course, a big selling point for 5.56 and 9mm was for NATO countries to have the same ammo where they could be resupplied by any with ammo compatibility.

    Not sure that would/will be a very big problem anyhow.

    Yea, I knew 5.56 was NATO - I just didn't know whether or not this 6.8 is, was, or will be as well.
    Waiting for somebody to note the similarity in size between the 6.8 and our beloved .270! :D

    Just my thoughts if they change to 6.8 I'm sure we will see a lot of bullet development with "heavy for caliber" higher BC values, as it stands today we really dont have any long range 6.8 - 27 caliber bullets,, who knows maybe the 6.8 will become the caliber of choice for long range shooters. 

    The question now is if they change are we all going to rush to re-barrel some rifles to the " newest and greatest of all times " ????

    I doubt that, if the platform stays the  M16.  No room in the magazine 
    That's good for us, a new rifle will be developed just like the M-1 to M14 than we can all go out and buy another rifle, and everything we need to re-load for it.

    Good news - we can’t be accused of owning “Military Style” ARs after this changeover.

    I think it is a good choice, a compromise between the 5.56 and .30 caliber. Looks to be manageable for all soldiers and gives them better range and more punch.

    Yep, it appears to be a new platform designed around the 6.8, not the 5.56

    A military rifle in .270? It must be because of that whole allowing women in combat thing.

    Saw that - maybe even .270 Kurz or .270 Corto!
    I don't pretend to know all the ins and outs of the new caliber, but these kinds of things interest me - looking forward to learning.

    We all know the .270 bounces off a gophers hide at 50 yards...  how will this help our military?  

    But seriously, the 6.8 will provide additional punch and distance, but the idea behind the 5.56 was a weight savings over the .30.  Seems like a backwards move.  Why not a lighter .308?

    same diameter bullet. The 6.8 uses .277 diameter projectiles as does the .270 Winchester and the .270 Weatherby Mag.

    However, the AR 6.8 uses lighter bullets than are standard for its big brothers.

    What parent cartridge is the new, bestest ever 6.8 based on?  Or is it a fresh idea.

    AR's will soon be on the MilSurp racks right next to 95 Mausers and Arisakas!

    I personally think it's a stupid move. A rifle round in 6.5mm would make more sense to me. With bullets of the same weight, the 6.5 will ALWAYS have higher BC than the same 6.8mm bullet, and that will translate to better accuracy and flatter trajectory with some decent load development. The 6.5mm bullet already has a track record on game AND humans, and is just a better choice, IMHO. And for civilian use, the 6.5mm has a huge selection of bullets compared to the poor ol' 6.8mm. Given the same case capacity dimensions the 6.5 will be faster than the 6.8 round, and with superior BC, be at the target with superior velocity.

    And the .270 Win.  is still a .30-06 that was picked before it was ripe! :D

    .30 Remington case - not necessarily the whole cartridge...

    There are certain fruit that are used in both their green and ripe state for different things. The Green Papaya for instance is used as a stock for thickning and flavor in certain soups. It and the mango are used in their green state shredded to make a salad called Asara. So the .270 may be green but it serves its assigned purpose well.

    From what I have read they are not considering the 6.8 SPC  which is based on the old .30 Remington case but rather developing yet another cartridge with possibly a proprietary polymer case.

    I'll believe it when I see it.
    Let's see, the FN SCAR was going to replace the M4/M16 and a multitude of other "vapor ware"
    rumors have been all over the web for a few years.
    Is the M4/5.56 the "be all, end all"? No
    However with hundreds of thousands (millions??) of rifles and hundreds of millions (billions world wide???) rounds of ammo out there, I don't see any major changes in my lifetime.

    The concept of a new rifle is assinine.it not just the rifle, but the cost of millions upon millions of rounds of new ammo, magazines and related equipment. 
    The AR is modular enough to do pretty much anything they want to do with it without rewriting the book with a new weapons system.

    Or maybe that wound the bad guy thing. Wound them and it takes 2 others to carry the wounded guy :smiley:

    I have noted over my lifetime that there are some enemies we have fought that don't bother with their wounded if they are wounded so badly they won't survive. Just leave them lying where they fell to bleed out and die.
