I cant decide between the .223 and the 6.8 uppers.

I know that the ammo thing is a definatly a negative thing.  but the ballistics are much better than the 5.56.  Besides in about a year the 6.8 should hit with a thunderous roar.  Whats you guys think out there?

If you really beleive that 6.8 will become very popular in about a year, I'd wait until then to buy - because then more manufacturers will pick it up, and the ammo will get much cheaper.

Being an early adopter is almost always much more expensive, and you have to be the "beta tester" and deal with teething problems of the new technology.

I like to shoot and with Ammo that is reasonbly  priced with good availability.

As to the Terminal Ballistics, No Argurement, but their are other rounds out their as well that are terminally better then 5.56.  No magic bullet, no one shot death ray.  Guys of been killin bad guys for 35 years with it, I suspect we'll kill a few more  before it ends it's reign. Get some MK262 or TAP if you worried about the terminal Ballistics.

me personally, I think the above poster 's anology is pretty good. I think the 6.8 is gonna die and go away, just my $.02

And if I'm wrong and it takes off, then great, once it's established, then maybe I'll get one.(Established in my book is me finding it at all the Places I go to now to buy ammo)

I look at this way:

If I shoot someone with my rifle more than 25 ft. away, even inside my home, I am going to have a hard time explaining that to the DA.  If I shoot someone inside a car, same story.

If it is a SHTF situation, I am not going to be able to realize it soon enough to grab all the supplies I'll need anyway.  I'd rather just be competent with a decent rifle at reasonable ranges.   The 5.56 should do that.  That said, I have a 6.8 SPC upper in a box, in case ammo prices come down as it is a superior round, but at a higher cost.

My "concept caliber" upper shoots as well or better than my "common caliber" uppers do.  It's funny, because it makes larger, non-conceptual holes in things too.  Plus, recent research demonstrates, that a "concept caliber" upper can be swapped out for a "common caliber" upper in a matter of seconds.  Or, I can just grab one of my complete "common caliber" guns.

The 6.X rounds are much more real than any imaginary UN force that will come take our guns away.  They aren't dirt cheap to shoot, but neither are a lot of rounds out there, which doesn't make any of them any less "real."

Yes, the ammo thing was kinda tricky until SSA stepped up.  I have over 600 rounds of 6.8 now, but would like to have more.  I don't know if I will ever have enough, but that's more a function of what I want, not a function of what's available. ;)

I've got lots of 5.56 too- since that's what I shoot more of anyway.  I would recommend that anyone in the market for an AR begin with a 5.56 gun.  Since it is the standard, it just makes more sense to get accustomed to the normal gun before venturing off into other calibers.

We can go back and forth on this subject forever, with no certainty whatsoever. Only time will tell what happens to the 6's.

I'm building a 6.8 because I want one. Not to replace my 5.56 weapons. Just cause I want one.

I don't see the ammo ever getting down to 5.56 prices - unless it gets picked up by the military. I like to keep an extra 2k of ammo around for my primary long guns (ARs, AKs, M1A/FALs). Right now, I don't think my 6.8 will be one of my 'primary' weapons.

So, if I had to choose (which is the basis of this thread) I'd go with the 5.56. Get the 6.8 when you have the extra $$$.

Why buy anything, well because I want to.  Sometimes I have to compromise to avoid budget guilt.
So my thinking is if you like to tinker with it and you can afford it why not.   From what I've read on here a civilian using an AR for self defense with controlled expansion rounds in a 1/8 or  1/9 barrel at room to room ranges is better off with the 5.56 in the light loads to avoid over pentetration.
If you want to shoot game bigger than coyotes, then 6.8 or 6.5.  If you are in the military and you want stopping and penetration  and penetration with stopping then 6.8 or the 6.5.  If you have the money 1 of each in three different barrel lenghts plus in three different gas rod actions. More AR's for everbody bartender.

Blanket statements like that are usually false. Next time you pull into the lot at the SuperWallyWorld to grab some bread and a six pack on your way back from the range, look at the far side of the lot and imagine a traffic stop.....and the officer pinned down behind his car by a guy with a shotgun.

Hey, it was the first thing that came to mind. Other things are more plausible. Just so long as the guy isn't standing there "when the flag flies" trying to figure out if the guy is 25 feet away or 26 feet. FWIW, I am hard pressed to think of ANY scenario where a civilian is in danger and must return fire at more than 100 meters (1 city block or so) or face death. Much more likely is that someone else is in danger.

Ah, how about UT-Austin, August of 1966? From the tower to the farthest victims was roughly 400 yards, if published accounts are to be believed. Citizens returned fire, but made no hits (the guys who entered the tower excluded).

People really seem to get lost on the concept of the 6.8x43 SPC. Its not a wonder cartridge....
Its not even as good as the other 6.something *6.5 Grendel* It just happens to be the biggest/ most 7.62 like round that will fit in a standard 5.56 mag well. Thats it. Thats all it has going for it.
As a civilian round, at least now, its pointless. Militarily, the 6.8 SPC is dead. It was nothing more than a "knee jerk" reaction in response to incidents of poor lethality from M855 and M4 carbines.
Mk262 is a much more reasonable solution than adopting a third standard rifle cartridge. Using the Mk262 gives you the advantage of increased lethality and use of standard weapons

components. The 6.8 SPC is inferior to 7.62x51 NATO in almost every way. While its not quite as heavy, its close...atleast its heavier than 5.56x45. The weight increase between 7.62 and 6.8 is minimal and the difference is notable compared to 5.56. Also, magazines, weapons and ammo are readily availible in many forms for 7.62 and will be for some time. The 6.8 SPC has peaked, it will not be adopted as the 5.56's replacement. It will never be adopted in great numbers. Soldiers carrying the Mk12 are realizing there isn't much difference between the Recce and a light combat load with a Mk11 or M25. The only thing the Mk12 offers is reduced lethality and capability

compared to 7.62 counterparts with a negligible savings of weight. If you are bent on 6.8 wait and see if it catches on as a sporting round....it wont, but you never know or start to reload. Paying a fortune and stockpiliing 100 rounds at a time just isn't practical, especially when the round really isn't that great. If you don't want 7.62 NATO then get 6.5 Grendel superior in every way to 6.8 except when used in beltfed MG's. Just like people say, "Remember the 6mm SAW?" in a few years from now they will say "Remember the 6.8 SPC, what ever happend to that round?" Don't waste thousands of hard earned dollars on a dead idea.

I'll agree that weight is a disadvantage of the 6.#'s. But NOT when comparing 7.62NATO ammo!

While both 6's weigh about 28% more than 5.56NATO, the 7.62 weighs between 53-66% more (depending on bullet). Plus (correct me if I'm wrong), I don't think there is a battle-proven 7.62 rifle platform in the same weight category as the AR-type. So, the gun is heavier too.

Now, you might make a good argument that the Grendel (with 144gr. bullet) could be a good replacement for the 7.62 - with the possible complication of potential feeding issues. I wouldn't argue that point too much. It's long-range performance is outstanding. But if long-range performance were the most important criteria, we'd still be issuing only M16s (or M14s). I believe short to mid-range terminal ballistics was the most important criteria. In that arena, the 6.8 takes a back seat to none of the above.

But, let's be honest. The 6.8 not being adopted by the mil was not based on any performance criteria. It was $$$ (or the lack thereof in the right hands).

That's good info - 28% weight penalty is significant.  That means one or two less magazines.  Plus the magazines themselves are heavier.  

As for light 7.62 rifles no one would want to shoot it very often.  The 9-10 lbs. kick enough as it is.  I guess you could get used to it but if you start to flinch you are just punching air anyway.

In real life, the 6.8 mag holds only 28 rounds. So, the actual weight difference between the 5.56 30-rounders and the 6.8 28-rounders is about 20% (plus the 2 round difference). IIRC the weight of a loaded 20-round FAL magazine is also about 20% heavier than the 5.56 mag (with a 10 round deficit).

DISCLAIMER: Most of my figures are from memory of comparisons I've seen, but my memory may be off somewhat. I do believe I'm in the right ballpark, however.

OK, fine, you're basically admitting, as is plain fact, that the 6.5 Grendel has superior external ballistics.

Now I have a question (and I promise I'm not going to get into another 6.5G vs 6.8 SPC thread here — maybe after SHOT Show 2006 . . . ).  

Here's one simple question for you, Forest: What would it take, in your mind, for you to hold that the 6.5 Grendel is a superior combat cartridge to the 6.8 SPC? Exactly what would it have to do, what performance specification would it have to meet — compared to the 6.8 SPC — to earn that title, as far as you're concerned?

Do you want to hear about fragmentation?  

As far as I can tell, the ONLY real benefit of the AK over the AR is a slight edge in reliablity and maintenance (offset by a slight disadvantage in accuracy and sights).  Both rounds have strengths and weaknesses, and there is no particular advantage of the 7.62x39.

People who imagine that being hit with an M16 would allow a people to "get up and run away" but being hit in the same place with an AK would die are completely out of touch with reality.  If you get hit in an extremity with EITHER round, of course you can "run away" - but if you get hit in a vital area with either round, you are NOT getting up.

Knock down power?  

Is that a technical ballistics term?  How do you measure that?



If the 6.8 is SO MUCH BETTER than 5.56, how exactly do you explain that the military has no interest in it?  The military leadership wants soldiers to die?  The Bush administration doesn't want to win the war on terrorism?  Big conspiracy among traditional ammo makers?

Not trying to flame - just trying to understand why all the decision-makers in the military don't seem to understand what is to obvious to you.

AFAIK, the 6.5G hasn't really shown much in the terminal ballistics area. And before anyone says that humans aren't made of ballistics gel, let's all agree that (while not perfect) it is the best indicator of real world performance. Professional, side by side testing will show who's the winner in wound infliction. I'll already give the Grendel the nod in long-range accuracy and ballistics. We'll just have to see how the rest of the comparisons come out.

I say, let's wait and see what happens. Alot of Grendel fans hope that SHOT will take care of the biggest complaint against the G - limited sourcing. I hope so too. I can now buy all the 6.8 ammo I want. I hope soon to be able to build my own Grendel upper. If that becomes an option, I'll do it. We're just not there yet.

In the time-honored tradition of AR15.COM - buy both!

Basic stuff.

A published report using standard IWBA testing methodologies showing the effects of the round on 10% calibrated gelatin with the standard cloth layers; with details to include depth to yaw, size of tempory cavity, size of permanent cavity, % fragmentation, max depth achieved.  Also showing ranges at which the round will still fragment would be nice.

I'll leave the penetration tests (auto glass, sheet metal, drywall) as optional - but again they would be nice.

Remington is the biggest reason the 6.8 SPC has gone no where to this day because of the lack of ammo.  As far as SSA production of 6.8 they are using Remington brass if I remember correctly. So the way it is right now the 6.8 never was really alive to begin with, and is just a wildcat that happened to have some factory ammo made.

Forest: OK, so we'd have to find a bullet in the 6.5 Grendel that "meets or exceeds" the 10% gelatin performance of the 6.8 SPC, if we assume, for the sake of discussion, that the 6.8 SPC exhibits "optimal" specifications in gelatin for this class of cartridge.

Given that, which 6.8 SPC test results would we be using for comparison? The original preproduction loadings showing the 115gr Hornady OTM at 2697 fps from a 16" barrel, or the actual final production versions, which are somewhat downloaded?

To sum up: If the 6.5 Grendel simply exceeds the gelatin performance of the 6.8 SPC, you'd declare it a better combat cartridge than the 6.8?

Not another 6.5 Grendel verses the 6.8 SPC thread.

Take it easy, there, Joe. I said I'm not taking it there. I'm not going to argue; I'm just seeing where Forest is really coming from.

And even if it were a 6.5 vs 6.8 debate, I can't imagine why it would ever be locked, so don't worry.

No problem "carry on"

Here's one simple question for you, Forest: What would it take, in your mind, for you to hold that the 6.5 Grendel is a superior combat cartridge to the 6.8 SPC? Exactly what would it have to do, what performance specification would it have to meet — compared to the 6.8 SPC — to earn that title, as far as you're concerned?



Basic stuff.

A published report using standard IWBA testing methodologies showing the effects of the round on 10% calibrated gelatin with the standard cloth layers; with details to include depth to yaw, size of tempory cavity, size of permanent cavity, % fragmentation, max depth achieved.  Also showing ranges at which the round will still fragment would be nice.

I'll leave the penetration tests (auto glass, sheet metal, drywall) as optional - but again they would be nice.




I'd add to that some reliability testing.  

The 6.5 is going to hog out even more of the bolt face than 6.8 does.  

Also the mags that I have seen for the 6.5 have done away with the 2nd corrigation or fold in the mag body.  To my mind this fold does two things.  It stiffens the mag and allows dirt and sand in the mag to fall free instead of binding aganst the brass cases.

Also the shape of the 6.5 cartrige does not look like it would lend itself to feeding as well as the shape of the 6.8.

These are just some thoughts without any proof either way.  But I'd like to see that 6.5s can run as reliably as 6.8s.

how well would the grendel work in a belt fed mg?
