!!!!!!!!!!!!!!!!!!!!!!!!!!!!THANK YOU FOR THE UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
300 ordered, been waitin' many a months. D |

Darn....Now I cannot be the only kid on the block with a 1000 rounds of brass sitting around! I could of made GOOD $$ on that brass! Rest assured I didn't gouge the market!
|
|
Now that all of this brass is coming in and we are about to have a bunch of busy reloaders, what is your favorite load for the 6.8?
|
|
Thanks for the tip. I've been waiting since December for new brass. 1 case of 1000 on the way:) |
|
|
I've been very happy and have great results, accuracy and velocity wise, with the Hornady 110gr OTM on top of 29.5grs of AA2230. YMMV. Now that I've got some more brass on the way, maybe I'll start experimenting with the heavy loads again. Stephen |

What are the fragmentation velocities for bullets that would be best for military or self-defense use? I apologize if this info is available somewhere on the site, but I have searched the FAQs and the load data without finding it.
A better way of asking my question is how far out does the 6.8 maintain reliable fragmentation in self defense loads? Thanks |
|
Refer to the original FAQ thread here for a blow by blow account of everyone's favorite (and hated) loads. Or you can check out my 6.8SPC loads page for what I've had most luck with. For the VMAX, my gun likes H322 and Reloder 10X. If you use a shorter bullet (like the 110gr Sierra PH soft point), you can probably get away with a bulkier/slower powder. -z |
|
|
The 110gr VMAX is the best anti-personnel bullet for 6.8SPC. The 115gr Hornady OTM is next. I don't know exactly where the new 115gr TMJ from Barrett falls in. I don't have an exact number for the fragmentation floor for the VMAX, but it is still fragmenting at 2000fps. -z |
|
|
So, the 110 g. VMax will fragment out to almost 300 yards--impressive!
Another bullet question I have been wondering about is how the 6.8 performs against targets inside standard vehicles, for example military or police using the 6.8 at roadblocks. How does the 6.8 perform against auto glass and sheetmetal compared to 5.56 loads? Great info, Zak. |
|
Just like every other rifle caliber evaluated for barrier penetration, there are other loads chosen or optimized for barrier penetration vs. bare/clothed flesh. A bullet that performs optimally in flesh will fragment, deflect, etc, when it hits a barrier. In 556 and 308, there are barrier specific rounds which stay together and deflect less through typical barriers. Same in 6.8, except the info has not been published yet (AFAIK). But if you look at what type of bullets perform well through barriers in 556/308, it should be pretty obvious the kind of bullets that would do so in 6.8. And there are a couple available now. A hunting bullet for deer sized game with good penetration is a good place to start... -z |
|
|
Assuming the same type of bullets were used, say the best antipersonnel rounds instead of bullets intended for penetration, do you think the 6.8 would perform significantly better than the 5.56? I would think the greater weight and the good velocity at close range would make it so.
I have been thinking a 7.62 carbine would be the best all around weapon, considering its better performance at long range and against vehicles, but the AR15 platform is so handy. It seems maybe the 6.8 is a good compromise. |

You didn't say exactly this, but I wanted to clarify that there isn't a HUGE difference in wound profile between the former and the latter. The VMAX is essentially a varmint bullet, and it happens to produce a wound profile with a very short neck, explosive fragmentation, and enough penetration of the major chunks. A controlled-expansion hunting bullet might have a little less fragmentation and end up with one major chunk penetrating the desired distance. Compare the 6.8SPC profile in the NDIA powerpoint set to this 308 JSP profile ( www.firearmstactical.com/images/Wound%20Profiles/308%20Winchester.jpg ) to get an idea what I mean. The barrier/penetrative/bonded load is no slouch in bare gel, nor does it have too much penetration. As for your actual question, I agree-- I can't see how a similar bullet design in a larger caliber would do worse. -z |

Thanks.
Maybe someone would enjoy shooting some car doors and windshields with the 6.8? |

Wow, I called yesterday and got the LAST case of 1000. The gent on the phone told me he sold 5 cases himself in the morning. As of yesterday, he told me he had 80 cases of 500 rds, and a slew of 100rd cases. Word got out quick, especially around here! |

I called Midway this afternoon and talked with a nice young lady.
I specifically asked if she could tell me how many cases of brass that they had received and subsequently sold this week. She asked her supervisor who said they only got a couple thousand pieces of brass total and that it was just trickling in. I told her I did not think this possible since they had already shipped me 1500 pieces and there were a bunch of other guys that ordered 500 count boxes as well. She asked the supervisor again who then told her the nasty rumor that the military had dropped the interest and Remington would no longer be producing brass and ammo. I can't imagine how this is true and that Supervisor obviously does not know what's going on as the supervisor did not even know that they had reveived and sold a LOT of brass this week. With that in mind, does anyone here want to volunteer to collect the numbers of cases that all the guys here on this board purchased from midway this week? It would be interesting to know... You can put me down for 1500 pieces which the midway website says has already been shipped. Randall |

Randall:
Glad you asked Midway I have been wondering myself. I posted that Midway had brass in stock and just from the few that I know ordered my guess would be over 10,000 pieces. Would like to see Remington stay in the game, but they have pretty much dropped the ball so far. I am more interested in Hornady's release at this point. Hope they will have product soon. On aside note the 6.8 SPC cartridge headspace Gage you made for me works great and takes the guess work out of die setup. Thanks Joe |
|
Put me down for 500 that is enroute via UPS.
ETA: I just got off the phone with Mindy from Hornady. I asked about their 6.8 progress, and she said they are still looking at sometime in Sept. for a release date, and related that they are definately on board though. |

Got an EM from Huntington:
We now have a limited amount of 6.8 Rem cases in stock. If you still want some, please contact us. Huntington PO Box 991 Telephone (530)534-1210 601 Oro Dam Blvd FAX (530)534-1212 Oroville, California 95965 [email protected] I received 300pcs of brass from Precision Reloading and 5 boxes of 115gr OTM R68R1........ primers are staked & sealed.........from Rat Worx. Hope this helps some. Zak, you have incoming, sir. Dave S |
|
You can add my order to the total. I just received an email from Midway that my 500 cases had shipped.
|
|
Just received a package from Precision Reloading containing a bag with 100 pcs of shiny brass headstamped "R-P 6.8 REM SPC". |

Hi gent's.I recently finished building my new 6.8 ,model 1 20" upper +r.r. lower.I got it to the range last week end and dialed it in at 50yrds,group's were about 2",nice and tight useing precision ammo s.p. 110."s.BUT... i did have probs with f.t.f."s several time"s.I noticed a short scratch in the same place on each cartrage..P.S.I was using a p.r.i. dedicated 15 rd mag.Any suggestion"s as to cause or solution would be appreciated.Thanx
|
|
Zak,which scope is that you have on that bad ass looking weapon of your's.
|
|
Any have enough ammo to have suffcient range time on full yet - to compair to 7.62 by 39?
Passed on a 6.8mm for the M16 for the first few years - ammo just too hard to find to really use in quanity. |
|
I know I am jumping in a little late, but I should have 540 rounds coming Tuesday from Midway.
I know that Midway lists a 115gr FMJ Remington bullet - has anyone seen them or worked up a load? I like the VMax bullets, but they aren't exactly cheap! Mark groups.yahoo.com/group/68RemSPC |

PROVO,
TA11 ACOG on my 18" 6.8SPC. JTinIN, Don't understand your question. The two are really different trajectory-wise. I use the same data for my 6.8SPC loads as I do for 75gr 223 and it's good enough to hit 12" plates to 600 yards. -z |
|
I don't know if this is working, as I am not very good with forums, but will try anyway. I will receive 1000 Remington 6.8 cases from Midway on 7-19. Just a short note regarding reloads for the 6.8 in reformed .30 Remington brass. A reasonable load in factory 6.8 Remington SPC brass produces a severe overload (expanded primer pockets, gas eruption, etc.) in reformed .30 Remington brass. This has been mentioned by J.D. Jones in other places. Has anyone else experienced this phenomenon?

unreal_scar:
Have had my dies for the 6.8 SPC for over a year, long before I could find any brass. I did have some .25 Remington cases though and necked up some dummy cases with no primers. Used these to check out function for magazines. Even early on it was stated that Remington had beefed up the case walls of the parent case. Loading data did not exist then and I personally decided to wait until 6.8 SPC brass became available. I was able to get 200 once fired cases shortly thereafter, and even then started with light loads and worked up. Many here have pushed their loads to higher pressure and velocity than I have trying to duplicate factory claims, and while they have come close are doing it at a cost in potential were and tear or damage to the weapon. When you wildcat a round like this with limited case volume you can buy into more trouble than you need. Especially if you try to get peak performance right of the bat. As far as the .30 Rem. case it can be done but it should never be used for max loads that the 6.8 SPC can produce. Think of it as a .44 Special compared to a .44 Magnum while they both will work in the same gun they are still two very different cartridges. Joe |

If you can find it. Finding loaded ammo seems to be much harder than finding 6.8 brass. There is at least one company that will sell you two boxes (20 rounds per box) of loaded 6.8 ammo, but you have to buy one of their 6.8 Ar's as part of the package. Can't remember off the top of my head which company that is. |

I received 500 -6.8 SPC brass today from Lock Stock & Barrel Shooting Supply in Valentine,Nebraska today (www.lockstock.com) 1-800-228-7925

I noticed the same thing when I was loading 28.0gr H322 with the 110gr VMax bullet. I was able to break in my rifle with the initial 100 I loaded, but noticed less stress on the cases and primers when I dropped it to 27.5gr (also had no shoulder brusing with this load).

J-A-R:
Your analogy to the .44 special seems to be right on. I believe that you are exactly right. I wish that I had communicated with you and the other members of this forum several months ago. I am not new to reloading for the AR15, but am very new to the 6.8 mm SPC. Thanks. |

Was thinking more along the recoil impulse of the 6.8mm possible being closer to 7.62by39 than .223 loadings. For rifle shooting in the M16 haver more or less four choices (excluding pistol rounds and the 300 Wisper ... which might be another option). M193 type .223 70/75 grain .223 115 grain 6.8mm 120 grain 7.62 by 39 Be getting the 6.8mm was wondering how the recoil / clime was on full auto for a 3+ round burst. On full can really notice the differenc between .223 and 7.62by39. Guess could stick with .223 ... but does not realy work well on the steel targets (too many .308 shooters helping with target manufacture ;-). Thanks |

I wonder why the large primer pocket was retained. It would appear to me that the small primer would leave more material in the case head.

I've shot my 18" 6.8SPC upper (with 308 Vortex FH) on an M16 lower full auto. You can notice the difference over an M16/M4, but it's not out of line. Definitely controllable. With a comp or 'can, it should be even better. You can't really compare AK recoil impulse to an AR15, and I haven't shot an M4/M16 in 7.62 yet, sorry.
6.8SPC "rings" steel with noticably more authority than even the heavy 75-77gr 223 loadings. -z |
|
Not that I doubt you Zak, but how is it exactly that ignition reliability is improved?
David |
|
Ever notice how heavy loads of slow powders, especially ball powders, sometimes do not ignite immediately in cartridges such as 243 and even 308? The problem is exacerbated by cold conditions. The fix is usually to go to a magnum primer.
I believe the large primer creates a larger flame which will more reliably ignite the powder column in extreme cold. I haven't done the basic research personally, so I'm going on halfway-related experience (308/243 loads), what I've heard, and some guesses. -z |
|
Thanks Zak,
That's reasonable, I guess. The last work I've seen on the subject was Korean war era, so it probably isn't valid. David |
