6.8 Dead?

Is the 6.8 SPC now dead for military applications? I've got a round sized non-SF guy telling me how SOF is going to the 6.8 exclusively...

I hope they do. Good bullet, IMO.

I think he is dead wrong.

Lots of reasons it isn't going to happen, well documented here.

IMHO, we are going to have a mix of M-4s and SCAR-Hs along with M-249s and M240s. No 6.8 in the future, AFAIK.

May make a decent LE round though.

6.8

GEN Schoomaker plainly said we are not going to have a bullet for SF and a bullet for the rest of the Army.

Then came the .40 for the boys and so on and so forth.

Probably we are going to migrate to the .40, but 6.8? Who knows.

Right now they are trying to figure out how to give Colt shyte-tons of money to re-cofig all the M-4's into gas piston guns.

And we saw how the "new" SF .45 project went down the tubes.
Now, supposedly the idea is back at SF command.

We'll see.

Gas piston conversion is a smart move, should of happend years ago. I can put hundreds of rounds thru my M4 and the bolt/carrier are barely dusted with residue and not really hot. Doesn't need to be oiled either (hardly) and we know what dif that makes in the sandbox.

Piston is the way to go, with the 6.8

From the reading that I had the chance to be associated with, The 6.8 seems to be the best round to use. I would think that a piston system would be a good selection as well.

With all the different piston systems available, I just can't understand why our military can't decide. Remington ACR looks quite nice with their recent reductions in weight. With SOCCOMs decision not to use the SCAR Lite, obviously, we need to make a decision and stick with it.

We are definitely going to have to re-arm with all the weapons reaching their life span. We need to make a decision... 5.56 is reaching it's end in adjustments or modifications and a decision to move into the 6.8 with a new piston based rifle seems to be the best move.

If anyone knows the right way to go, it's you guys. I sure hope someone is listening.

My M9 still shoots 9mm...
...my M4 still shoots 5.56

If I run out of ammo during a gun fight, I can grab magazines from an afghan commando, or another American, or a Brit, or any one else in ISAF that carries 5.56. So, why would I want a gun that leaves me unarmed once my magazine runs dry? 6.8 is a gadget round. It may be the best single bullet on the planet, but if you cant support the logistics train behind it, why make the change?
Besides, it is my observation that most folks who claim 5.56 simply is not capable of knocking down bad guys have not really been very many deployments...
...or else they think that the dirt kicked up at the feet of bad guys should be killing them as it ricochets past them. I have watched guys unleash automatic weapons fire at a bad guy... pock mark the shit out of a stone wall, and then bitch about how ineffective 5.56 is against bad guys. Well, even an M2 wont kill a guy if you embed the rounds in the wall instead f the bad guy.
...maybe there is a self-aiming version of the 6.8 that I am not aware of.

...just my two cents.

We tested the 6.8 back in 2005. The test targets were steel silhouettes hanging by two wires. When shot with 5.56 they gently swayed. When hit by 6.8 they violently rocked back and forth. The recoil was not very much more than 5.56 and the upper took 28 round mags. We said it was superior to the 5.56, but reccomended against it due to the very logistical reasons you stated.

As far as the lethality of 5.56, I've personally seen a guy shot 5 times in the chest with green tip at 40 meters from a full sized M4, who then dropped his PKC and ran 30 meters away...died while running. It was a disconcerting experience. No drugs were found on him or in his stuff. His buddy went down with one round, which went through the heart and spinal column together.

I'm not going to discuss the 5.56 at length, that's been done elsewhere.

Let's see....

This discussion has been had on many threads here before.

We have a rifle and a carbine that are working and have most of the bugs out of them over the past fifty years or so. We have a SAW that uses the same ammo. We have a heavy rifle, a GPMG and our sniper rifles using another round that is adequate out to almost 1,000 meters. We tested alternate weapons, and the troops preferred the existing rifles in the lighter caliber, and were only marginally in favor of the SCAR-H in the heavier caliber.

The 5.56x45 is a proven round, when used within its effective range. You will not have a sexy little 10.5" seven pound carbine dropping people like a death ray at 500 meters unless you are making head shots. A 20" 5.56 rifle is pretty effective with body shots out to 250 meters or so. Closer is better, though I am not convinced that the 6.8 is a significantly better round at the combat ranges we normally engage at.

We have two established calibers that we sold to our other services, allies, and NATO. We have hundreds of thousands of SMGs, carbines, and rifles with Eugene Stoner's direct impingement gas system. When clean, maintained, and using good mags, they are reliable weapons.

There are probably billions of 5.56 rounds currently in bunkers in the U.S. military ammunition system.

At a time when we are cutting retirement benefits, asking soldiers to pay for their families' health care, and kicking combat proven soldiers out of the military to save money, why in the world would any rational person think that we are going to cut more to pay billions of increasingly rare dollars for a new operating system for more than a million weapons, and buy billions of rounds of a new caliber?

Maybe the people who dreamed this 6.8 scheme up?

I don't see this happening.

Why would I carry a signature round that states definitively that I have been on the objective? Why would I carry a weapon that I cannot get resupplied with ammo for, but from one source. As been stated, we have too many weapons using this round and Special Ops does not need a signature round that just complicates everything.

I have heard all sorts of stories about the 5.56 round not dropping someone, my experience is that it does right readily drop someone. Hell, I have seen some guys hit with 45s and not drop, does this make the 45 round a wimp round? Some guys just have a high tolerance to body trauma and this makes great anecdotal stories, but proves jack. These stories have been around since the late 60s claiming the 5.56 round is a wimp round. I call BS.

You have some people that have invested a lot of money in a round that was predicted to take the world by storm, it did not. Now they must make something off their investment and stirring the pot is the only thing they have.

My 2 cents again.

Instant death caused by GSW is due to a vital organ (or organs) being hit, usually the heart or parts of the brain. Most other GSW will not cause INSTANT death; however, they may lead to death by blood loss, shock, respiratory failure, or even, over the long term, sepsis. Pain is not a cause of death. As many of you on the site can attest, spending time with multiple GSW's, unless you are in the craft of understanding ballistics and body composition, no one round is better than the next if you can't place a well aimed shot.

Brush Okie, Our M16's were lethal. It could be one of those things, some people die real easy, some die real hard.

Our only problem was poor information on maintenance when the M16 was issued, so it picked up a very bad reputation until that FUBAR was fixed. We can argue about ballistic until the cows come home, but IMHO, the most important factor is the person holding the firearm.

Phencyclidine is some bad stuff that's for sure. A LEO in the county where I live was killed after the suspect he was trying to arrest pryed a service shotgun and it's mount from the dash of the patrol car, chambered a round, and shot the officer. I've heard other stories from friends who are LEOs about suspects under the influence of PCP breaking their hands or wrists while trying to get out of their handcuffs. Failure drill I believe is the best remedie for anyone in that condition and posing that serious of a threat.

The agency that I was in, we were issued Mod 19 Smiths (.357 Mag). PCP, brought up the concept, hey we should have .41 Mag Smiths.
