mllm,

yes John's website at www.65grendel.com has a large amount of detailed information on the forums.

For a quick overview, click on the link at the top of p.4 of this thread (Wikipedia) or go to www.wikipedia.org and type in 6.5 Grendel.

The .300 Whisper and the 6.5 Grendel have significantly different capabilities.

Thanks for the info on that link. I don't really do any specific type of shooting. I am not in the military. I just like my ar-15. It is too small for deer & hog hunting. I just want to purchase a second upper for general purpose hunting, shooting.

For general purpose use, the 6.5 Grendel is probably the best pick for the AR15.  You can hunt medium size game including deer and hog.  You can do long range hunting as in mountains or beanfield.  It qualifies for major class in most competitions.  It is highly accurate for target shooting - 1/2 MOA or better by all reports.  You can get inexpensive ammo from Wolf at $10.99 a box or less.

The .300 Whisper is a fairly specialized and ammo/reloading costs will be higher.

Update and historical info from Bill posted at www.65Grendel.com

www.65grendel.com/forum/showthread.php?t=1772


The 6.5 PPC was the original wildcat that can be dated back to Dr. Palmisano (one of the P's in PPC) and I actually own a match winning target of his that was shot with this caliber. The 6.5 PPC was rediscovered by a number of shooters over the years, but my contact with Arne came during our experiments with this caliber in the AR. At the time Arne was shooting a 6.5 PPC that Scott Medeshia had built.

With that said a cartridge will always be a wildcat until commercially produced brass, dies, ammunition, guns and mags are available, and the most difficult piece of this jigsaw is the brass. From previous work I already had contacts with Lapua but the Grendel started as a reality when their head of R&D brought me a drawing for the 338 Lapua Tactical and asked if I could design a rifle. I could not see a good market for the cartridge in the US so asked instead if they could make a Grendel case. History will witness that putting a 6.5mm case design in front of a Finish engineer is a safe bet.

The case design was refined with the help of Lapua. I had already thickened the walls in the area of the mouth and shoulder but I had not moved the shoulder quite far enough forward to ease production (Longer case necks = more production rejects) Lapua finalised the neck length and I then recorrected the case taper angle.

The next piece of the puzzle was the design of the compound throat. With bullet ogives running from 6 diameters up to 19 diameters and the OAL of loaded round strickly limited by the need to fit the magazine, it is impossible to produce an accurate design that will safely chamber all ammunition using a conventional design. The compound throat is unique in the industry and allows Grendel AR rifles to digest a wide variety of bullet types all with good accuracy. The design could only be initiated when brass was finished, as the effects on operating pressures had to be taken into account. This little conundrum took nearly two years to sort out.

The final puzzle piece (I hope) was the magazines. Looking to drop +$300k on tooling is not a prospect one rushes into with a competitor shouting about military adoption. Suffice to say that that problem has faded and the mags you see today are a far cry from what we started with.

Grendel now continues to evolve. Saterns proved out the use of 5 groove 5R barrels. I am finalising load work on the 130 Scirroco and I see that Barnes has a very nice looking 110 solid spitzer. LBC and Blackhills will bring further combinations I am very excited about and then there are the bolt actions. WOLF has the first 180,000 rounds in my shop now (pics to follow).

Wolf is adding steel cased 6.5 Grendel ammo in addition to their brass cased Gold line - steel cased stuff is due 2nd Quarter 07.

www.65grendel.com has now added its 1000th member!  An increase of almost double since five-hundred and something last year.  Congratulations John on a successful website.

I'm interested in buying a 6.5 Grendel Upper from Alexander Arms (despite the long wait I will probably have to endure). Their website unfortunately doesn't give very good details as to the specs of their 24" Advanced Weapon System Upper.

Anyone have the scoop on this Upper? The Rail System it uses, the gas block, is the barrel threaded? Anyone have pictures of Alexander Arms various Upper Assemblies?

Thanks!

I'm not going to consider you credible unless you can find a report to verify your opinion or at least what brand of bolts that are breaking.

Unless you can back that up with facts (documentation of bolts breaking), you are just trolling.

In the first place I've owned a SR25 in 308 win and I wouldn't own another, (too damn heavy) 2nd place, you have any real first hand documentation that Grendel bolts are breaking? Or is this M9 covert

Wolf 6.5 Grendel ammo is now available for sale on Alexander Arms' Website.



In the beginning, there was Alexander Arms ammunition with premium Lapua brass at $1.00 a pop.

Now we've got Wolf 6.5 Grendel brass-cased ammo at 50¢ a pop.

I hear Wolf 6.5 Grendel steel-cased is on the way. Price?

So, my question is, does Wolf ammo count? I would love to get a POF or another piston-driven upper in 6.5. I guess POF needs to be convinced that there's actually enough demand, and that commercial ammo is available.

Thanks!

fnfal et al:

Yes, I've seen that, as well as the Wolf gold and the steel cased stuff (out yet?)

I guess the question why doesn't that compute with POF? What will it take for them to accept that "commercial" ammo is available?

Which brings me to this question: what would it take to buy a 5.56 or 7.62 upper and make it a 6.5? Is it as simple as a barrel change? Or is it alot more complicated than that? I'm brand new to the 6.5, but am loving what I'm hearing, both here and also with the local rhetoric at the HiPower matches I attend. Just don't know how to get it/build it in the platform I want yet.

Thanks,

Schultze,

Any good leads on decent 6.5 bolts and barrels? I know this is a big topic, but would appreciate y'all's favorites for these two items. Only the bolt and barrel? Man, that sounds too easy!

Would that only work on a 5.56 platform, or could it also work on a 7.62 NATO platform (i.e., POF's new 7.26 AR they have out)? Demonstrating my ignorance...

www.saternbarrels.com or something like that.  Barrel, bolt, and barrel extension provided.  Any barrel length, fluting I think, profile, etc.  Check 'em out.  They are supposedly a quality manufacturer.  AA is using them for the higher end builds I think.  They do .50Beo too, but we gotta get uppers with opened ejection ports for those first.  You can do it yourself, but it does not look good if you Dremel it.  The 6.5G upper receiver is a stock one by the way.

That's great news about the WOLF ammo!  It became available while we were on vacation, and I found out when we got back that my 6.5G upper is on it's way from Montana!!  Wuhoooo!!!

Model 1 Sales has 16", 18" and 20" 6.5 Grendel uppers in stock now according to an e-mail I recieved last week! I'm not sure how everyone here feels about M1S, but I am willing to give one a try if they stand by their products. I e-mailed them back to get specifics about twist, bolts and barrel profiles. No responce yet.
Anybody got an opinion on M1S with their current 6.8 SPC reliability and accuracy? It dosen't have to shoot as good as a LesBear or AA for me. It does have to be dependable though.

Alright, I called Model 1 Sales today. The sales lady said that they had recieved a shipment of 6.5 Grendel barrels and were in the process of doing some testing on their own uppers. I believe she also said that they were waiting on some ammo. She said to check back with M1S in about a month to check on availablity but she wouldn't promise they would be ready.

After looking over scores of the usual 5.56 uppers at the Model 1 table at the gun show 2 weeks ago here in Houston, I asked the guy "So where are all your 6.5 Grendels I keep hearing about that came in". All he replied to me was a lame "They're back at the shop".

I quickly summized that I really didn't need to be sking him the obvious follow up question "Well, why did you leave them there in Illinois, when you and all the Grendel buyers are here now in Houston? I decided if such an almost incohernt and basically stupid reply was the the best answer he could offer me, then I didn't need to ask anything else. So, I looked back at him, waited a few seconds to see if that was all the had to say (it was), and I then simply walked away muttering to myself "What a moron".

I'm sorry if you guys think this post might be rude. But, it might serve to inform the Model1 peolpe that if it must proceed with disappointing it's customers after weeks of  anticipation, then perhaps they could act like they care when a frustrated customer ask them such a simple question.

If it was me behind that table, I would have responded with at least half a smile; "I'm so sorry for the delay. They should be here any day now. Can I call you when they are available?"
But what do I know?..... I don't sell gun barrels. I only run a service business and deal with people who pay my bills.

No, it was a stupid answer, and told me nothing of what the status was. And at that point, I really didn't care to hear any excuses...nor should I have had to "guess".

Above is the reason I'd hate to work in customer service industry, the man answered your question. Did you ever stop to think that with the negotiations that are going on with AA that they might not be at liberty to say much else? Either way grow a thicker skin.

foob,

you posted on the 6.5Grendel forum in the thrad about accuracy: So 5.56 isn't a 1/2 MOA rifle? You do know Les Baer guarantees 1/2 MOA on both Grendel and 5.56.


Far as I see reading Les's website he says they are 223's, not 5.56. The rounds may be the same dimensions, but the chambers definitely not.  I'll bet his chambers are of the 223 dimensions. So a 5.56 may not be as accurate as a 6.5 Grendel in the current rifles.

Um, The 7.62 NATO/7.62X51 is a .308 more or less, not .280. But you're right about the adoption of the 5.56 NATO bieng in the 60s. The 7.62 NATO was back in the 50s.

Personally I think the 6.5X55 Sweede would be ideal, but that's just me.

Jim, it was adequate, but not great. In my opinion, it was less than it should have been. I just blasted the stuff at 25 and 50 yards with iron sights, so I don't know accuracy. Does a .5 inch group at 25 yards count? I think the main thing I'd say is it was inconsistent. Ejection was generally at 4:00, a couple flew out at 2:00. Some brass flew one foot, some four feet. In chambering and unchambering without firing, I noticed some bullet set-back issues. Now that I've tried reloading the brass, I think the brass is either too soft or not springy enough because I'm not getting good neck tension (although some guys are reloading it just fine).

Conclusion? Good enough for blasting and hunting at 50¢ a round, but as far as I'm concerned the brass needs attention to be consistently reloadable.

John,

I thought my CSS barrel had the most non-existent throat there was, but the Wolf ammo chambers and unchambers without moving the bullet.  As you know I shot mine ammo with a scope at 100 yards and I thought it was damn good enough for hunting.  As Bill noted it's a little shy on velocity, but I think it will still do the job.  As you know the 6.5 caliber had a lot of penetration as it is so maybe the lower velocity won't hurt it none.  I have didn't reload my first box as you know because the primer pockets were too big, so I shipped it off to curlymaple and he's making key rings from it.  I've yet to shoot another box.

I would say Liability.  

Plus, you don't have to push the Grendel to get good results.  If you are comparing to a .223 which is the only fair comparison, you will always win in terms of energy and drop without hot-rodding the Grendel.

Not a production gun, but some guy named "bonehedz" posted on Grendelizer's forum a 6.5 AK. www.65grendel.com/forum/showthread.php?t=30&page=3&pp=25


Needless to say, I have full faith in the ability of an Avtomat to take just about anything. (By the way, I personally have converted two Saiga 7.62 rifles to Grendel, and although I haven't performed any torture/endurance tests with them, they seem to be holding up just fine, and since they're shooting match-grade barrels (albeit light weight) they will produce 1-1.5 MOA group offhand (optics mounted: I don't see much better than that anymore!). In my experience, AK accuracy (or the lack thereof) has more to do with poor ammo quality and minimalist barrels, not gas port size or any other design parameters. By the way, my qualifications make these statements: structural engineer by profession, with background in machining, welding, metallurgy, and welding fabrication. Worked in family custom knife shop while attended school (and after) for fifteen years. Amateur gunsmith (don't want to go pro, can't stand dealing with the Feds; mostly just work on my own stuff). Hope this clears up some misques, and I don't mean to ruffle any feathers...Bonehedz P.S. ALL AK mags I have personally examined have the same internal and external dimensions (not exactly, but pretty damn close); 74 mags feed 6.5 Grendel just fine, with only a little trimming to allow for case dimensional differences.



Blackstar and Gendelizer- to answer your questions in order: I made a feed ramp out of a diesel wrist pin (machined outside diameter, bored inside to required spec, plasma cut and griound it smooth, then contoured the ramp to match up with the top of the front of the magazine). Probably could have made it from heavy schedule pipe, as the rounds barely touch it, but I had the high strength alloy piece; why not? I drilled and tapped it to the bottom of the trunnion on one gun, on the other located it with a blind pin and silver soldered it in place (BTW, if you subscribe to the WECSOG theory of gunsmithing, learn to love the silver solder. You can bond dissimilar metals with a bond that has 125,000psi tensile strength. Most steels run between 65-70,000 lbs UTS).
As for the magazines, you can cram 30 rounds in a 74 mag IF you trim the follower length. The down side is that the rounds are smashed in so tightly you can barely lever the mag into place on a closed bolt (remember, AK's and variants, including Saigas, do not come with a last round bolt hold-open). I'm not sure how it affects reliability, as I stated, because I have yet to push either to anything resembling their limits. (Can't afford the ammo, but Wolf and Cabela's are changing that!!) So for now I've been loading 26-28 rounds per mag and they seem to function fine. As to modifying the magazines, I took just a bit off the front edge of the magazine to clear the fatter case, and shortened the feed lips about 3/16", to accommadate the shorter shoulder length of the 6.5G case. Grendel cases will load into an unmodified polymer 74 mag, and will feed after a fashion. They kind of "jump" from the feed lips, though, instead of stripping smoothly. Also there was a significant amount of drag, none of which enhances reliability. On a side note, however, none of the modifications seem to affect feeding of the mags when loaded with 5.45x39. As to barrels, I got a chamber reamer from Pacific (listed under gunsmithing on AA's web page) and a couple of barrel blanks from Pac-Nor in 6.5mm, and chambered them myself. I don't know if I'll go tha route again (terribly time comsuming if you're doing it on a rare occasion, and bloody nervve wracking as well!!!). Most barrel makers can turn you a blank to your dimensions: I'll be detailing all these mods shortly, including machinists' drawings for your barrel maker. Milling/ drilling the gas port and nothching for extractor clearance are about all that's left, and if your barrel maker does semi-autos, that should be no problem. Bonehedz



..I have blasted a couple of mags rapid fire, after modifying them, and they work just like they would in any other Avtomat; when you pull the triger, it jumps around. When you pull the trigger fast it jumps around a lot. But every time you pull the trigger, it jumps!!! BTW accuracy is very good, considering these were the first barrels I've chambered ALL BY MYSELF (look Ma, no hands!), and I wasn't trying for a match rifle anyway. But so far, they are as reliable as any of their less-pedigreed cousins, and shoot as well as any military type rifle I've fired. Recoil is about the same as a 7.62x39 AK. A more ergonomic stock will aid in quicker follow-up shots and controllability. Not that it's bad now, but there's always room for improvement. Bonehedz

Thanks.  So it's been done as a custom job, but no production runs from any manufacturer?
