I don't know if this has already been posted, but Browning is making a 6.8 SPC A-Bolt.  www.browning.com/products/catalog/firearms/itemdetails.asp?cat_id=035&type_id=012&value=001B&cattype=035012&item=035012281

I guess there will not be a Winchester.

That's good news.  The price is especially nice.  

cool... coated stainless steel 6.8 mag w/ c/s spring for under $30. im placin the order right now. also a good excuse to get some of the misc. springs that are feelin worn out.

Denny`s has a small run of 16 inch Recon barrels and bolts in 6.8.  

Have been wanting to get a caliber designated lower for my rifle now I finally have one. Now I just have to finish putting it together.

Do I smell a "group buy" for these mags?
HMMMM

It's too bad that the 6.8mm SPC is dead in the water and only the Grendel has survived...  

Nice looking rifle!

Not sure if I detect a note of sarcasm...........

Instead of being bitter about the Grendel's success, why don't we all raise a pint together and celebrate being freed from PRI's mag monopoly as a fringe benefit of the work that Alexander Arms put into making high quality/low cost 6.5 Grendel mags available from CProducts.

If Wolf's 6.5 Grendel ammo offering is profitable, maybe Alexander's efforts will again help 6.8 SPC fans by proving (to Wolf) the buisness case for obscure niche products and they'll be willing to offer low cost 6.8 SPC ammo.

I'll raise my big cup of coffee to that!

good report, keep'em coming.

I am getting the impression that out of the 16 in bbl, the 6.8 is generating about 1500 foot pounds of energy.  If so, I am really wondering what the big advantage over .223 is.

I have been considering the .243 AR idea.  I know it takes the AR-10 sized lower.

Energy isn't the only issue, but it's a significant factor.  You also need to consider diameter.  A .270 caliber bullet is 21% larger than a .223.  If you believe that a bigger hole may improve leathality, then theres a +1 for the 6.8.

The 6.8 also has a significant energy advantage over .223 for both short and long range shooting.  At a point blank range, the 6.8 has almost 700 more ft/lbs of energy than the .223 and maintains a significant improvement in energy out greater than 600yds.   I see that all ranges the 6.8 has a huge advantage over the .223.

In any case, the terminal balistics for 6.8 are significantly better that the .223 and unless you really want an AR-10 lower, the balistics for a .243 don't warrant the investment (in my opinion).  I'd rather have a lower that can shoot 223, 6.8 and 9mm with a simple change of the upper and magazine.  If you are going to invest in an AR-10 lower, you would be better off shooting .308.

Energy (ft/lbs)
Bullet                      Muzzle 100    200    300    400    500
.223 55 GR           1282    939    675    473    323    220
6.8 REM115 GR   1966  1561 1224    947    723    549
.243 115 GR         2002 1641 1333  1072    853    674
*** Note:  These figures are not based on velocities for a 16" barrel.  The actual energy would be less for all cartridges due to reduced velocities.

Or 7mm-08.  Myself, I'd like to see some .270-308...6.8 Super.

Slap that doggy's ass, BLouie!!!!  

army_eod,

Hi Guy!  AR-10s are not light, even when compared to a 20" HB 6.8mm SPC.

There are more than a few guys that have posted on ARFCOM a pelethera [bwaahaahahahaa, never used that word in 48 years] of legit data on the 6.8 that I believe you have missed.  

Sometime soon, get your favorite drink, cigar, what-have-you and enjoy the search.  The first post on page #1 of this thread will direct you to 99.8% of what is worth knowing.

Hope you get a 6.8 very soon.

Stay safe with that EOD stuff.

Dave S

Bitter? No such thing.....I'm merely parodying the doomsayers who pronounced 6.8 as RIP after shot. Rather I am celebrating the fact that its demise is greatly exaggerated.

Back to the scheduled programming.

Paul - Please send the brass ASAP!

I am building another 6.8SPC upper. This one is a CMMG,Inc Mid-Length upper w/ Gov't Profile, Chrome lined. Has anyone had a load worked up for a upper from this company? Any info would be appreciated.Thanks in advance!

A little hot.

String 6 and 7 were Hornady 115gr HPBT and Hornady 110 Vmax.  Velocities basically identical to the Barnes. Both loads are a little hot.  I am going to try H322 powder next.  

Basic conclusion. 20" bbl is a waste of bbl steel in the 6.8.

rjay, I checked my data for my 20" M1S chrome moly barrel ('04 manufacture). I can use 28.0 grs of RL-10X with 110 gr. Hornady V-Max, Hornady HP and 100 Sierra SP for around 2600 fps. That is with Rem. brass ('04 manufacture) and Rem 9 1/2 primers. OAL is 2.305". You by chance have one of those tight bore chrome lined bbls?

RJay,

Do you have any data on heavier bullets - between 130-150gr?  I'm curius as to how much the increased bullet weight affects velocity.  I'm more interested in getting a 6.8 round into the subsonic range.

Sorry, this is something that has no interest for me. You can get a lowend chrono pretty cheap. It's a great tool.

Any suggestions on a good chrony?  I've been considering the new Pact, but I've read several negative reviews so I'm a bit leery.  

Look here for some Ideas and reviews. I personally use the Prochrono Digital w/o the accessory remote control. It works fine for me.

I bought the Chrony Beta Master for $127 and of course a week later it went on sale for $10 off.  The lowend Chrony for $70 something would be hard to beat for a bare bones.  I wanted the remote display on the bench.  Everything else is just bells and whistles .

rj

I've used a Chrony F1 for the past twelve years and last year got a Bata Master Chrony to get the remote readout. No problem. Comes in a steel box and takes a lot of knocking around and still performs well.

I sold my PACT......

I shot over an Ohler 35P, woo hoo that was nice!  Wish I could afford one.  Well given what our guns cost I wish I could make the Ohler a priority to buy...

I like the Oehler, in fact I think the Proof Channel technology is a great feature of their system.  I'm concerned that they have temporarily discontinued production due to a problem with a parts supplier.

I presume the chrome-lined 6.8SPC  barrels from CMMG and other similar vendors are still by ER Shaw or its subsidiary.

I know there were initial teething problems with these barrels; are these current 6.8 barrels in proper chamber spec now?

Thanks!

I have a couple questions for you owners of 16" 6.8 barrels.

Are you using a carbine gas system or midlength gas system?

If you had/have problems with a particular system what were they, what cured it and which system?

I am considering adding a 16" to go with my 20" 6.8.

I had a 20" 6.8 Shaw Chrome lined barrel and switched to a 16" 6.8  Chrome lined Shaw for a handier package. I had no problems with either one shooting my handloads or loadX. The only two loads I've had access to. I've only put 2 boxes through the 16" but like it. Shoots 1" to 1.5" at hundred but am waiting for the snow to move out before giving it further testing. Carbine length gas system on the 16".  

Quoted: Are you using a carbine gas system or midlength gas system?

Midlength and I've had no issues.

CMMG has a lifetime warranty and they manufacture all of the uppers. They are a first rate group to work with. From what source do you get your information from?Thanks

For some reason I thought CMMG and several others (Bravo Company, etc.) all had their chrome bbls mfgd by ER Shaw (or its OEM distributor) and then chromed by US Chrome.  The early batches of ER Shaw 6.8SPC bbls apparently had problems.

I guess I was wrong about CMMG, at least.

Just want them to do an 18" middy 6.8 chromed bbl ;)

CMMG is in the process of looking at doing some different barrel configurations at this time.

I shot a wild hog last weekend with my 6.8.

When I headed out the door I thought I was going coyote hunting so I grabbed a mag full of Vmaxes.  When I got to my friends (four hours away) we decided it was way too warm and windy to have any luck calling.  But, he said he knew a guy that had about 60 wild hogs on his place and would let us hunt them.  So, Vmaxes be damned, I was off to hunt a hog.

When we found and cought up to the hogs it was getting very dark so I did not feel like I had time to try and sneek them again and risk running them.  So I decided to take a 200 yard shot.  The land owner was adamant that we take only boars becasue he is trying to grow the heard.  I had a 4x scope and it was getting dark so the only way I could tell what sex I was shooting at was to wait untill a boar mounted a sow.

The shot was difficult.  The hog was quartering toward me while on a sow.  It was 200 yards out in low light.  And, I only had a 4x acog.

Anyway I hit it and it screamed like a stuck pig.  The rest of the hogs ran off from it, but it quickly regained it s feet and fled, moving just fast enough that I could not close on it befor dark.

We fond it the next night, by itself comming in to a creek for water.  This time I was able to get within 80 yards.  My first shot was  broad side runnig.  The pig did not react. I quickly shot again, this time at about 90 yard and a little more quartering away.  Still the pig did not react.  My third shot, at about 100 yards, sent the hog end over end.  He got up, took about ten steps and fell over dead.

We quickly gutted him, took him back to my friends and skinned him.  This is what we found:

The first night I shot him, I hit him a little far back but right through the ribs.  Since he was quartering toward me the bullet missed the vitals.  It must have fragmented compleatly because there was no exit wound.

The first shot on the second night was right in the vitals.  It compleatly shedded both lungs (which explains why he did not scream like the night before)  there was no exit wound.

The second shot went in the same hole in the hide, but because he had quartered away a litlle this shot shredded his heart.

The third shot went under his belly and hit his right front knee.  It almost severed his leg off.


I know vmaxes are less than Ideal for this aplication.  But,  shots one and two of the second night killed the hog as dead as any gun/bullet would have.  These are tough bastards that can run several yards without lugs or a heart.

I don't know if this tells us much about 6.8 but I thought I'd share.

Even something like the BArnes X bullet probably would not have made any difference on your first shot.  I mounted a 2 to 7 on my 6.8 just so I would be good for point blank stuff and still have a decent power for longer shots.  I sometimes wish I had have gotten a 3 to 9 or 10.

I am amazed that someone thinks they need to encourage the hogs. He will be overrun pretty quick.

It is here in Colorado. There are not many of them YET.  It is on pasture where there is not much they can hurt.  

i think the 5.56mm is a EXCELLENT antipersonnel round, when the RIGHT ammo is used. a 5.56mm soft point, or a hollow point leaves a really nasty hole. does the 6.8, 6.5, and 308 have more power, than the 5.56mm? of course.  if your a civilian, and can use decent ammo types, the 5.56 is good. if your stuck with fmj, then the bigger the better.  i buy and keep soft point and hp ammo for defense, and hunting, and use the fmj where it belongs, for plinking. personally im looking at the 6.8 right now to add to my kit. i was looking at a remington tactical bolt, but am really thinking of a upper now. i wish they would quit making new crap. just when i think im satisfied with what i have, they make some new nifty crap, and there goes a new lay away. im the lay away king. sigh

Better watch out around here, everybody thinks that tumbling or fragmenting M193 is better than a controlled expansion softpoint or polymer tipped bullet.
