I'm an old fart, and it's so much fun to see all these cartridges come out for reasons based on marketing! It makes me feel so old though. I remember going to my local hardware store, and gazing in awe at the big center fire cartridges there, while waiting for Mr. Hunter to ring up my 50 cent .22 LR purchase. I remember the free brochures made available from Remington and Winchester! I would pour over every cartridge and compare the performance of the different rounds. Oh how I wish that one of my old brochures survived! I wish all you young people could go back in time with me, and see what hunting and shooting was all about back in the days of my youth!

As a disabled vet and master armorer, I have owned the 6.5 Grendel about 15 years now, and 6.5 Lapua in a custom bolt gun for 10 years. In black rifles, we run the Grendel, several 5.56mm with different barrel lengths and rifle twists (one 26-inch, one 20-inch, one 14.5-inch, and the rest in 16-inch), 5.7x28mm, and one in .22LR (not including the 18-inch .50BMG on an AR lower). I have been shooting the M16/AR15 series rifles for 37 years (which includes shooting expert in the Army for 18-years). I'm not one to jump on the latest and greatest black rifle caliber of the month. I spend time doing research and verifying data and/or claims, (talked to the designer of the Grendel for 4 hours on the phone) and in many cases, we do our own testing digitally comparing the group-size/accuracy of firearms and ammunition, shooting high-speed video with our two high-speed cameras, HD Video, and even multi-point audio. this year we also added a special through the scope camera for shooting 4k point of view video of the target (and other technologies) all for social media such as the weaponeer channel. And I have to say that the 6mm ARC is the only caliber I would purchase for testing without all the "research". Why? Partly based on my own knowledge of ballistics and the black rifle and the other part based on Hornady Manufacturing's reputation being on the line. We rarely get to shoot Hornady Ammo (We would shoot 100% Hornady ammo if we could but on an Army disability pension and a limited production budget it's not possible) but if Mrs. COVID-19 hadn't cleared out our 2020 budget, you could bet your ass we would have picked up a barrel, bolt carrier assy., and Hornady ammo for a video series on the 6mm ARC testing rifle, and accuracy. and then testing 6mm ARC vs 6.5 Grendel. we would also love to test two AR's in 6mm ARC with one being Standard rifling and the other being Polygonal rifling to see if there are any advantages in bullet velocity and/or accuracy. unfortunately, it's not likely to happen this year. We have plenty of extra lowers on hand but companies want over a grand for just a complete upper these days and building one is still around $600+ each, so it gets expensive very quickly, not including the man-hours of testing and then editing! So, with no budget remaining this year, and it would consume all off (and likely more) of next year's budget, and we can't have our whole year budget-focused just on the 6mm ARC. This makes it unlikely we will get to it before everyone has videoed it to death in lessor detail, and in the clutter never find our videos. that said, I may try to build a 6mm ARC for my personal collection next year. It will be hard to justify when I already have the 6.5 Grendel, but I do like collecting accurate and fun rifles. of my AR's the Gredel is my favorite, so it would be troubling if it's accuracy was outclassed by the ARC lol.

[@jeffcamp9008]

Thank you for your service you make some very interesting points , I have also carried the M16 and own an Ar two of them one left one right handed and am intrested in changing the left since I am right handed I'm very intrested in a new cartridge like creedmore, grendal but the ARC has caught my eye.

[@TexanUSMC8089]

Look at Bear Creek Arsenal for complete uppers. I bought a 350 Legend upper with bolt carrier group for $250. I've had a 6 Predator for a few years, and 6.5 Grendel for 7 or 8 years. I think the 6ARC would double the effective range for our military.

[@COYDOGSBAND]

@@jeffcamp9008 It's funny, before Tom Beckstrand's "announcement" in G&A, in 2009, a test was being run at a security firm I was at (under TITANGROUP/L3--which had a jointly run DoJ/DoD PSD program protecting municipal officials in the end of 2010s era VS the DTOs hunting some of em) and holy smokes..First off, I saw the first .300BLK which, like many, I was pitching a serious tent to see such a thumper being so quietly employed (subsonic AR rounds were new to me as I was now in DFEs but not a mil veteran) but then, the 300 HAMR arrived--as no one else wanted to try it/field it...and so was the Grendel. *NO BS, NO JOKE...our fmr SOF and fmr FLE guys that ran the RATTLR (L3 COMM) teams that transported folks back then, all were trying to use the BLK or 77gr Black Hills and that was it. Then we met Bill Wilson when we went to train in Arkansas one week w/another civ firm, and we got our hands on 300 HAMR...And like the ARC from what I understand? THEY WORK IDENTICALLY. I would get either an ARC or the HAMR (both are simple barrel changes if i recall correctly, maybe a mag diff...but not extensive changes like other modular ARs) but still...If you liked the Grendel?? Here: So even on the civ IC side of the "gun work"/PSD world? We used BOTH in ACTUAL DFEs in real world conditions. Now, I was still utilizing my DPMS 5.56 14.7" rig,and I wasn't doing anything sexy or getting too kinetic as a mere 'terp/consultant and trunk monkey in the convoy, meaning I was the last victor...HOWEVER, on a few diff days, I got to experience some of our runs from Chula Vista to TJ to Nuevo Laredo all the way to even Rosario region/AO w/the Grendel in the only time being raised in anger that I know of (cue the getting laughed at) and when the 300 HAMR would run, when the Grendel would run, they all just seriously outdo even .308/7.62 does imho...No joke* By the end....without too much detail, for a scrawny, non-vet, non LE loser like me to go from being a bilingual rangemaster in San Diego to doing THAT job with those guys? Guys who taught FAST Team courses, HRT, fmr SOF and frogs etc?? They allowed me to finally put my DPMS down and try the 300 HAMR, which was identical to the Grendel imho....so when I saw them using the ARC after I'd left not long ago??? NO ONE believed that it was being used in the priv sector let alone in the very SMUs these guys had spent the 90s in!!! lol...here we are... I'm so glad the "hog hatchets" of yesteryear did exactly what we always claimed, regardless of the Dick's Sporting goods type counter-lingering snobs who harangued staff and fmr LE guys, becoming the crowd who'd scoff at us saying "77 grains?? You don't need that....I do plenty with the standard. Why do all the old phogeys need their precious .308s?? What can't you aim??" or the joke said BY guys who were fmr military to our fmr SOF (but not saying it aloud) instructors and later on, our ICs and S.Os, would be "sooo wait...you are spending all this money on .300BLK now? But before the complaint was the LACK of lethality in a .22 round the ENTIRETY of NATO uses? Wow....no wonder you couldn't hack it in the box!! bahaha!" ...ugh.. *Point is, not only does the .300 HAMR and 6mm ARC, downrange (I only speak for the HAMR), but both were tried by the firm...or at least the ARC's cousin, a round called like the "6 mil dash" or "6 mil dasher" was what the burly f....king frog and two Unit dudes called it...and they, again, were out...not at the Command anymore, but when those guys got them a few years ago, the 90s veterans I'd assisted over w/L3 were using that variant of the 6mm (and were also using the .300 HAMR vs the BLK)*

I think it will be a great cartridge and there is room enough in the market place for both it and the 6.5 Grendel. Just like there is room in the market for 6.5 Creed and 6 Creed. When the wind picks up, my heavy 147 eld match 6.5 Creed outperforms the 6 creed all day long, especially when hand loaded with RL 26, and velocities over 2950. But with no wind 6 Creed out does me at the matches. I do agree the 6mm ARC on paper will slightly outperform the 6.5 Grendel. However, due to the Grendel's bigger bore, it can get a little more velocity with a shorter barrel. I would like to see it on paper, the 6ARC with 108 bullet vs the 6.5 Grendel with Sierra's 107tmk BOTH out of an 18" barrel. Im betting they are neck and neck and almost exactly the same. This is the problem with the 224 Valkarie IMO is that the small-bore diameter means it needs a long barrel to burn all the powder.

Its takes a bit of engineering validation to get a SAAMI spec. Which is nice because it’s in the public domain now and you’ve got 20 barrel manufacturers and not one little shop spinning out three barrels a month. The 6AR and 6ARTurbo also have IP royalties which is why the dies and barrel reamers were so freaking expensive. And which is why they never took off.

@Hornady Manufacturing What's going to be done for a budget ammo option? The 6.5 Grendel has a $0.24 to the current panic buy price of $0.28 a round with Wolf. That's a huge factor in not only getting people into it but keeping them into it. So will there be a $0.22 to $0.30 a round option for the 6mm ARC, even if its offered in a steel case?

[@MrBurdinekl]

Good question. I fantasize about a 6mm AR pistol, rather than a 5.56... a more true do everything round. If a good 6mm AR or AR pistol is produced I could see 6mm ammo prices coming down due to the popularity. As a recon Marine, I longed for a 6mm rifle and cartridge to be adopted... That would really make it affordable for civilians and potentially turn every Marine rifleman into something of a sniper.

Apparently they liked it enough to buy it.

The new bolt head rim is considerably thinner than the 5,56 rim and has not been combat tested. The Mags? Good mags almost always need tweaking. What happens if you have to do some mag dumps in a tight situation? Will they feed properly and will the thin rim hold up under a lot of heat and stress? Don't know if they will be issues....

It's really just them trying to make a proprietary cartridge, problem is, if they don't make it widely affordable it won't grow. 6.5 Grendel is it's parent case, and rather than letting magazine makers get the final kink out of the system, they went and downsized the cartridge slightly making it cost way more than fixing a magazine.

Since Hornady was the first ammo maker to get behind the 6.5 Grendel in a big way, it was an easy transition to the new round.

You say you can use 6.5 bolts -- but there are two types of 6.5 bolts: type I and type II. Most manufacturers (of barrels/chambers) seem to have settled on "Type II."

Will be interesting to see what barrel life would be in a premium cut-rifled barrel. My dedicated prone rifles in 6BR UBL w/105gr VLD's (2985fps) would start to give up that guilt-edge accuracy at 1700rds and start pitching wild 9's at 600yds after 2000rds. My guess is that under similar conditions (slow-fire prone), these should go 2200+ rds using available 103-105gr projectiles. Where this cartridge will REALLY shine is in the NRA Tactical Prone class (if they still are involved in competitions). The NRA Highpower Committee in their infinite stupidity, has allowed ANY caliber instead of restricting the game to the 223/556 caliber that 95% of AR15 safe queens use (THE people the game was intended to draw). As a result, this would be the exact caliber of all available that I would campaign to consistently win that game...my opinion.

Ar 10 pistols yes, no need for such a large cartridge just to limit it with such a short barrel. However, taking a large bore pistol round and putting it in a longer barrel is the way to go for a pistol setup. More barrel than a standard pistol means more velocity, means more power.

Why would I get a 6 ARC when the 6.5 Grendel is already an established cartridge that does essentially everything the ARC will do other than maybe being as good at paper punching, and it will use the same projectiles as the bigger 6.5 creed that’s already massively popular. As far as systems are concerned, if I stock up on 1000 projectiles of 120-140 gr. 6.5, I can use it in both and get great performance without having to use a separate projectile and use the same ballistic calculations with a change in velocity.

Sorry you guys lost me at 6.5 Grendel Bolt. You're going to run into the same problem the Grendel has which is shaving down a 5.56 Bolt face to run it that's a no-go for me and that's definitely a no-go for the military. Unless you build an AR around a specific cartridge its not going to pass the smell test. LWRC is the only company that stepped up and built in AR-15 around a cartridge which is the 6.8spc

[@Paelorian]

That problem is fixable with better design and materials. With the increasing popularity of cartridges sized for the 6.5 Grendel bolt I think these problems will be overcome soon with newer products on the market. However I agree that if we scrapped compatibility and went to proprietary rifle designed around the cartridge then we can have the ideal cartridge and rifle performance. But it sure is expensive and inconvenient. Maybe if these cartridges get popular enough we'll see new ARs that are slightly larger than AR-15s but smaller than AR-10s. That's what would be perfect for 6mm cartridges with ideal velocities. The Grendel variants (including 6mm ARC) are as much as we can squeeze into the AR-15 but if there was more breathing room they would be better cartridges and the rifles would be more reliable. The ballistic king as I see it right now is the 6GT (almost a 6mm Dasher but it feeds better, similar to 6x47mm Lapua but it's more forgiving when developing loads) unless you go up to a much more powerful cartridge like the 6.5mm PRC. Unfortunately the best 6mm cartridges are just slightly more than the AR-15 can handle, which is why we have almost-there compromise cartridges for the AR-15 including the 6mm ARC. It's a great compromise but even as they say in this video it can only be "90%" of the performance of the best 6mm rounds like the 6GT and 6mm Dasher. If we had a slightly larger AR and magazine we could get 100% of the performance without having to go to a much larger AR-10 designed for .308 Winchester. For now, I think I'm willing so sacrifice 200fps to get a AR-15 instead of an AR-10 but AR-10s are getting so much better and more compact that I'm not so sure I even want to sacrifice that 200fps. Maybe I don't need a rifle lighter and handier than a POF Rogue, which is pretty much an AR-15 that takes 7.62x51 mags. But those mags are bigger and heavier with less capacity. 6mm ARC seems "good enough" to enable the AR-15 to pretty much "do it all" except hunt big game (not including medium game like deer for which it is fine with good bullets) and shoot with terminal effect at very long range. Doubling the effective range of the AR-15 without crippling it's ability in close quarters is a real accomplishment and a superb balance even if I want that last slight edge of Dasher performance (it's hard not to want the very best). If I need more power to hit further, I'll consider 6.5 Creedmoor or 6.5 PRC. The 6.5 PRC is probably a better companion to the 6mm ARC since they're not as similarly powered, though I prefer autoloaders. But it's very appealing to me that the 6mm has so little recoil that the rifle is much more versatile. No other SAAMI cartridge with external ballistics this good has so little recoil, making it a very versatile cartridge. Long range is fun but we all know most real-world shots are taken within 300 meters. With 6mm ARC, I don't need to substantially sacrifice performance at 0-300m where it matters most to get the ability to accurately place longer shots. I expect a good 6mm ARC gun to be effective at 500-600m and capable of hitting accurately but weakly beyond that.

It is an absolute necessity for caliber success.. and after 1 year, developing better chamber dimensions/reamers also is going to be necessary for success. MANY barrels built off of the hornady chamber dimensions are struggling with accuracy.. which relegates them to "mag dumpers" in the end anyways. I truly hope this cartridge works out.

Actually it’s a slightly necked down 6.5 Grendel with the shoulder moved back a bit and a different taper. Oh wait, that’s actually pretty different. Looks like the only thing it actually shares is the case head size. Also, the military has next to nothing invested in 6.8/270. The 6.8 thing is still in the development stage and the only thing finalized is the issuing of the requirement. There’s several companies in contention for the contract but nothing finalized. I don’t think this thing is going to change the world by any means, but the fact that it has already been officially adopted by a JSOC unit does give it some advantages. 6.5 Creedmoor is a similar story. It is so close to a 260REM that they almost should have been sued for copyright infringement but it’s hugely popular. Even DOD has gotten on board with the 6.5CM. It’s the caliber of choice for the new production m110’s. So prepare for a lot of surplus M118LR to hit the market in the next 12-18 months. I’m honestly skeptical of any “new” cartridges that get released like this though. I was interested in the Valk when it was announced but fortunately didn’t jump right into it and given all the problems that it’s had actually getting the 90gr bullets to group I’m glad I didn’t. It was a lot of build up for very little result. The amount of energy it carries at long range does me no good. I’m not a PRS guy. But I’m interested in this one. The controllability for fast follow up shots plus the extra energy it carries combined with the factory support make it an interesting cartridge for me. I’ve loved 6mm AR for a long time but really didn’t want to deal with the issue of forming my own brass. This gives me the same capability but with major manufacturer support.

I've seen JP BCG's already so I bet barrels are soon to follow. However have you tired a Proof Research? Maybe it's time to do so their carbon wrapped barrels are light and shoot very well.

What's velocity out of 16 20 inch barrels?

[@K-bob_45]

Barrett had a post saying 2650 from an 18 inch barrel

Is the 6ARC better than 300 blackout or 6.5 creedmoor?

[@geologik7500]

They aren't even in the same category. 6.5 creedmoor is a short action cartridge that won't fit in an AR15 platform and is generally 200 FPS faster than this. 300blk is designed to be shot out of short, suppressed guns at close range.
