Ep. 012 - 6mm ARC (Advanced Rifle Cartridge) 

BRASS, BRASS, where's the 6mm ARC BRASS come on already Hornady!!!

There is a lack of 6mm ARC brass. I wish Hornady or another company would start pumping it out. Bolt gun 6mm ARC here and love it!

6 ARC has become my absolute favorite hunting cartridge here in Texas. I love it!

Love the 6mm ARC, Just need more ammo

Please start cranking out more 103gr Precision Hunter!

I like this quote from 10:55: "Chamber design and cartridge design, when done correctly - and, usually, together - you can kind of mass-produce accuracy."

Hornady needs to push other Ammo makers to put out different 6 ARC rounds.

6MM ARC NEEDS TO BE PUSHED more than it is at the moment.. Still not that easy to find and reload ammo! 6MM ARC has become my go to caliber when you can find ammo, i pick it over any of my several calibers i own.

Well I built a 6mm ARC shot it and sold it only wish I had was ammunition availability other than that very accurate and a joy to shoot and if ammunition was more readily available it wouldn't have been sold

Built an 18" 6mm ARC in an AR platform and absolutely love it! It has become one of my top 3 favorite cartridges.

Hey. Here's a thought. Instead of introducing catridge after catridge. A novel thought would be, "How about we fulfill the market need for EXISTING cartridges first?"

When will we be able to buy that magic pixie dust you guys use in your factory loads? I can't make factory velocities with Levr without pressure signs

I started out CQB with an M2 Carbine in M1A1 configuration (old timer), modernized as time moved on and saw the eventual adaptation of the M4 as a good replacement and carried it. With reading about the 6MM ARC when it was released, with my past experience I believed the AR15 platform had truly come into the 21st century. I immediately bought an Aero Precision M4E with a 16" Ballistic Advantage barrel, some Hornady factory ammo and loading supplies. WELL DONE! I don't want to even get into the unbelievable accuracy, shoot ability and Ballistic performance, people would not believe it. Suffice to say fabulous wind performance tested out to 1/2 mile. The AR15 is now not only a true 21st century CQB and general purpose military rifle IT IS a state of the art multipurpose rifle cartridge combination for family needs.

Savage 6mm ARC owner here. Love it. Yes on the varmint load.

HSM making 6 ARC factory ammo now. Hornady making 80 grain varmint rounds. One request Hornady- give us a factory round with 90 grain CX Superformance! I said 3 years ago if this is well supported it can become a top 10 cartridge.

Please manufacture more brass. Please.

Have a uintah precision 6mm Arc love it.. bought 20 boxes fast as i could, easy to reload

Like the cartridge, but they need support from Ruger to go with Savage.

Might be a great cartridge if you could find ammo or reloading components. Have been waiting a year for brass!! I don't know you guy can shoot it. Hornady should make more brass

I'm way to happy with and way to invested in my 6.5 grendel to try another hard to find ammo for cartridge. Big reason I'm so glad I love the 308 and 223 so much .

Hornady, IMHO, YOU need to add some factory loaded offerings to the 6mm ARC. Currently, all of the loadings are > 100 grains and that's hurting the reputation of the round, because people think that it's just for long range. How about offer the same bullet choices as the 6mm Creedmore? Edit: What part of "factory loaded offerings" aren't you guys getting? Hornady has done a terrible job of showing the 6mm ARC's versatility.

New guy to the long range/PRS world. (Starting my 2nd season) I started out shooting a M1A in .308. Great rifle, highly impractical for PRS. (It's all I had.) I ordered a complete upper in Nov 2020. Fast forward Oct 2021 I finally score a aero precision 24" hvy barrel complete upper 2 days before our season finale. (Actually, noon, Thursday before the match.) I cleaned the upper, took it out, broke in the barrel, zeroed, came home, cleaned it again, threw it in the case. Friday afternoon fine tuned the zero, got my average velocity (with the help of a friend and his labradar), trued BC in my kestrel and went to work Saturday at the match. (Had all of 66 rounds on the rifle) Only shot a 45 BUT you have to understand I only fired 58(ish) rounds to begin with. (My time management sucked) The guys on my squad were highly impressed with the performance. And I quote "That thing is a f'ing laser!" Yep, it shoots nice. Out of the box shooting Hornady 108 Match ammo my AR shoots 1/2" groups at 100 yards. With Black ammo it spreads out to around 3/4". Velocity average for factory 108 ammo is just under 2700 fps, Black ammo is around 2725 fps. ES/SD from both ammo lines is amazing. Started load development recently. (Still have plenty of factory 108 Match on the shelf. Guess that's the benefit of waiting almost a year on a upper, plenty of time to buy ammo. lol) Right now I'm getting 2685 fps (avg) sd 4 ES 9 with 28.8 grs of leverevolution, CCI 400 primer using hornady match brass. (No flash hole de-buring, just anneal, size, trim, mandrel the neck, dump powder, seat bullet at factory length, go.) Like y'all said, I'm not worried about crazy speed, just consistency. I know leverevolution is temp sensitive but as long as the velocity change is known it's nothing that can't be dealt with. Have some N140 coming. Might drop velocity but shouldn't have temp sensitivity. Anywho, after all the rambling, absolutely love 6 ARC. So glad I discovered it before building a 6.5 creedmoor gas gun. Super excited to get this PRS season underway. Taking it out to vortex vengeance in a couple weeks. Keep up the good work Hornady. Love your products. (Yours are the only bullets I run,,,, for everything!)

That was my thing with the 6.5 Grendel as well. I didn't think the velocity was there for the bullets it was spitting out. 120ish bullets were going 2500 fps? You drop to a lower weight and you can shoot those in a 6mm bullet faster. Well said guys

Need 6mm arc ammunition and reloading brass on the shelves and online store, everyone is out of stock or coming soon.

So unless I’m missing something, this sounds like it would be ideal for feral hog eradication. Most ARs used for feral hogs are AR-10s in .308. 6arc would allow a smaller, lighter weapon. Just as hard hitting for getting through that dense animal.

I might build one, but I'm perfectly happy with my Grendel's from 12"-22". They hunt well and all of my Grendel's shoot sub moa, including my 16" BCA 😳😁. Grendel wins on ammo availability and cost (premium and plinking). I can shoot and stock up on Wolf steel cased for less than 80 cents per round.

Great job guys. I absolutely love my gasser 12.5” and 18” ARC’s. I’ll probably build another 18” for my son. Keep pumping out the Ammo.

The people want 58gr - 90gr factory ammo for it. Reloaders have proven it's very possible, clearly it's no .243win or 6creed, but it would be great for coyotes & bobcats with a 75gr V-Max. That's the only thing keeping me from buying the 6arc.

Pure 6mm ARC porn ;-) Climax around 30:00. Follow up spooning with the powder critique chat. DIY 6ARC Gas gun with Aero Precision parts and 22" barrel.

Need that 75gr vmax

Just bought a Ruger A.R. gen2 in 6mmARC. They made some good improvements to that rifle; the wedge is neat because of my shorter arms, and especially pleasing is the much smoother action. The caliber choice I made was because of the discussion I had with the very knowledgeable gunsmith at my LGS. Taking muleys or whitetail, and antelope at 600 yds sounded great! So, done deal. Looking forward to using this cartridge.

Full knowledge, full truth on the 6 ARC from the folks who designed, engineered and developed it. This was like going to "bullet church". Thanks for all your hard work.

Love my 6 Arc! Shooting lasers. Soft shooting hard hitting

I'm not going to mention his name because I dont personally know him . He was getting 2950 FPS with 105s in his 26.5" 6ARC Bolt Gun . I believe he had over 6k rounds fired in mid 2021 . Even in his 22" 6ARC gas gun was getting almost or right at 2700 FPS with Black .. 6ARC is my absolute favorite AR15 Cartridge. It's my do all be all . I absolutely love my 12.5 and 16" . My 12.5 is my do all be all AR15 RECCE Upper 500 yards and in . My 16" is my SPR and can easily get out to 800 yards . I have about 1000 rounds of 6ARC fired through my Rigs.

With a new cartridge they should sell inexpensive bulk target ammunition. As well as the hunting cartridges, etc.. Have a good deal on used STAG ARMS COVENANT 16" 6mm ARC. Decisions...

6 ARC just another flash in the pan, King today, forgotten tomorrow. I'm not biting.

ARC. Another Redundant Cartridge.

Such a sweet little shooter! However, can't find ammo, or components for the cartridge. Not to mention only Hornady loads 3 factory loads for it. This can't be a good thing for its future, right?

Come on Magpul we need some magazines

Just built my first 6mm ARC Love it minus ammo availability! Let’s go @hornady

Needs more adoption. I'm keeping my rifle even if I have to reload.

My 6mmARC shoots fine.But it does not come close to my 6 Dasher, or my 6 BR or my 6 GT.ooking at the 2020 Nationals not even one 6mmARC wa in the running or even in the top 50. Now with that said I love my 6mmARC AR15 Rifle.I am in the process of building a precision 6ARC bolt gun.. The problem is not enough rifle companies are building enough 6ARC rifles.Howa builds one and Savage. Who else is building one??? One other thing..Out of the 2020 Natio also there was only 1 guy placing in Top 50 shooting Hornady Bullets. 95% shot Berger .There were 4 shooting Sierra Match King. And 1 shooting Hornady in both the Light Gun and Heavy Gun.The lone Hornady was the 300 PRC.. I hope the 6mmARC stays around.I really like it.I love my Hornady products.But to be competitive I had to switch to Berger Bullets.i hope Hornady can come up with a better bulket equal to Berger For years Tge Federal Match King in 308 was the benchmark bulket.Now Federal is also using Berger in their Bullets too.

So many missed opportunities. The bolt and barrel extension should have been redesigned & strengthened to tolerate greater bolt thrust. Have you wondered why you haven’t heard a thing from the unspecified “DoD Agency” (generally thought to be SpecOps).

Great cartridge! Needs more support from hornady, and they need to get other manufactures on board, or it will sadly die off

Got a cmmg resolute love it but we have to get more people on board with ammo also what is the latest word on the dod using the six arc

If you have a 5.56/223 lower, you can build an upper for this caliber with a 6.5 Grendel BCG, 6mm ARC barrel, Upper, handguard, gas tube, gas block, muzzle device and 6.5 Grendel magazine. All of these parts can be shipped to your home. That's the beauty of a caliber like this.....with HUGE ballistic advantages. Unless you're shooting 5.56/223, 7.62x39 or 308, you're paying a TON for ammo. You can also build 224 Valkyrie, 300 Blackout, 6.8SPC, 6.5Grendel, 22 Nosler, 204 Ruger, and 300 Ham'r with ONE serialized receiver without modifications.

MAKE MORE BRASS OR THE CARTRIDGE WILL DIE!! WE NEED BRASS NOW!!

Let's Go Hornady. Steve Hornady forced the "Mandate" on his company. HE CAN SMOKE A TURD.

I'm planning on prairie dogs to mule deer, & black bear. 58vmax 8208xbr?? What load on the 90CX??

Hi Fellas,, it's been closing in on a year since this interview. How is 6ARC AMMO production today??

Why you guys dummied down the case capacity is beyond me. The 6mmAR had more capacity and people were running the same heavies.

Make some brass available !!!!!!

Where does the 106 TAP fit in, list BC is higher than the 108 ELD-M. Is the Tap ammunition what the DOD is using?

Still waiting on god damn brass 🤗

We had the 6mm SAW over 50 years ago, but no one cared. Eugene Stoner developed a series of interchangeable rifles, carbines, and light machine guns for that cartridge.

I would have loved it if they rebated the rim of the cartridge to .223 size instead of the larger 7.62x39 size of the grendel so we could use .223 bolts also.

AMMO...MISSING IN ACTION (MIA)!

It's Mike Ezell's 6 Grendel......

Bolt head on bolt carrier group....very thin, thin, thin..breaks Come on hornady...gun builder ...nah

It would be Great if you could Get into manufacturing Primers so we can buy & shoot more of your products.

Did you know balls stinky speaking you can get better ballistics out of a 25/45 when loaded close to the top end its better. You can question.

What length barrel, in a gas gun, is needed, to get the performance of the 6mm ARC?

Hornady "book max" is pathetic compared to what most people are actually running them at.

It 6mm ARC does what U.S. Special Forces need it to do. That said in almost every hunting or real life use where barrel length is not stupidly limited and bullet weight is not limited the origanal 6.5 Grendel beats it in every way. Not talking about number on a sheet of paper but real world use in target shooting and hunting. If you run the same weight bullets of like design in 6.5 Grendel as the 6 ARC it will shoot as flat or flatter. If you load heavier bullets or hunting specific bullets it eats the 6mm ARC's lunch! You have to make unfair comparisons and stack the deck to make the case for 6mm ARC over 6.5 Grendel. If you not cowards let me know we can meet up during good weather in Michigan where my crippled but lives. You can bring doppler radar and any other gear so long as all footage and data is live and made available to everyone for free. All bullets and loads have to be made publicly available. All bullets must be publicly available for purchase at the time of getting together and competing. Hornady will never put up or shut up because the modern Hornday is full of liars that fear the truth and far comparisons. They fear science, engineering and transperancy! They lied to their custoemrs about what was int he box and last I checked even after they where caught as liars refused to change the sticker ont he box! Your RU-vid channel is a marketing machine not a source of trut and light for the community and your customers! It is not that the 6mm ARC is a bad cartridge it is not at all it is a very good cartridge the problem is that the truth in not in Hornady and the company can not be trusted to be honest and make honest comparisons! Just like the absolute rubish comparisons between the 6.5CM and the 300WM that you company pushed and encouraged gun writers to make. You insult your customer base. You are basicly urinating in our face and telling us it is raining! I bet you wont invite the public toshow up wioth 6.5 Grendel and 6mm ARC for a show down and maybe toss a few pigs onto a smoker and have a good time! Your not that honest, open, and magnanimous to your customers and fans. You pretend to be though! I can not imagine Grace Hornady approves of the current corprate culture! Just my opinion though!

I contacted Starline and they are not taking on new projects and their technician said it wouldn't work because the primer pockets would stretch if you removed brass from the base. That didn't make since to me since it would be the same as existing 5.56! So I took two 6.5 Grendel cases and milled them down myself to fit my 5.56 bolt. I then put the 5.56 bolt in my 6.5 Grendel upper and have now shot each case 4 times and still have resistance in the primer pockets. One case is PPU and the other is Hornady. I'm pushing a 140 grain bullet with 21.5 grains of IMR4198 because I have a good supply of both. No pressure signs. I'm going to work up to 22 grains which should be near max pressure. I haven't chronographed this load and I'm not using the gas system for this test. I'm just testing the integrity of the base.

Laughable! BS Warning! Folks need to decide if you're talking AR Platform and its limitations or bolt rifles. I hear ya, 6mm ARC is great, but no love for 243 Win. 6.5 Grendel is great too, supposedly good enough to rival 6.5 CM, but no love for 260 Rem. Same groupies are saying 308 "is dead" and 30-06 is "outdated". Hmm, really!? BS

You could do the same thing with the 6.5 Grendel and the 7.62x39 with small primer pockets. This would practically eliminate the bolt breaking at the lugs due to the removal of metal to accommodate the larger cartridge bases.

6.5cm will always reign supreme in this area it seems a bit odd to try dethrone it because its so established. 6.5 ARC wont ever achieve that level of success, in the same way 17WSM and 17HM2 will never overtake 17HMR.

I would love to see a 22ARC

Pretty disingenuous to compare a 108 or 105 in the 6mm and just hand wave assume the best you can load into the 6.5 is a 120. Thats like comparing something to a 308 and playing like only 150s exist. The 6.5 loaded with the best bc loads it can take is absolutely splitting hairs with the 6mm, and has significantly more energy up close, and only barely looses out in the ballpark of 800/1000ish yard territory depening...

Please release a varmint load!

Too bad there isn't brass available. makes me look at 6mm creed.

Do you know if the company reversed it's vaccine mandate, and and made a comprehensive reimbursement plan for the employees whose rights were violated, and a way to cover any and all potential side effects of the vaccine? Short of a huge public apology, including such a plan for the employees, I don't see any way to convince me to be a customer again.

6gt shooting 109 bergers out of a 23lb bolt gun goin 2950 and ive never had trouble watching trace. Just got ny 22 inch ar10 going 2950, but havent broke it it or really tried to group with it. 6 arc us on the list to build though

Why don't you get into the primer business. I'm not buying bullets without primers. In fact. This lack of primers is making American companies looking really bad.

More excuses to shift ammo production capacity away from long-standing hunting cartridges. Worst of all is 6.5 CM because it was totally redundant alongside other existing 6.5 cartridges.

Flesh out, not flush out. One of my pet peeves. Look it up. It is based on taking a framework like a skeleton and adding the flesh as in fleshing it out. Flushing out is something you do to your car’s radiator and coolant system. 😬🙂

Is there any way of getting your guys to push 6mm arc in Australia

Hey guy's, can you put a 5 56 base on the 6mm ARC so that I can use my standard 5.56 bolt. You could call it the the 6 ARC (Gas)

Hey guy's, can you put a 5 56 base on the 6mm ARC so that I can use my standard 5.56 bolt. You could call it the the 6 ARC (Gas)

6mm arc Were hanging out for rifles and ammo in australia cmon man

Reload info is NOT RESEARCHED !!!

Would really love to see Mile's 6arc PRS gas build since it's mentioned in a number of podcast!

Self righteous nerds. Robert Whitley did this years ago and had plenty of build and load data. Hornady is notorious for trying to reinvent the wheel.

These videos are too obtuse, get into the cartridge, bullet weights, powders, barells and velocities ! Numbers please !

Been shooting a .243 for last 50 years, i should slow it down, save my barrel ?

Hornady; we made this new cartridge. Reality; 6mm AR pre dates the 6mm ARC. I'd hate to be the guy that developed and spent all the time and money in developing something just for so company to steal it. 👎

Where is the Ammo? I got a lame answer when I contacted Hornady with the same Question!

Love Hornady Ammo, but dang other ammo makers need to step up as well as rifle makers. is the 6 ARC fading out like the Valkery ?

Until there is ammo, brass, barrels in 6mm ARC there's no point. Get the brass and ammo out there or this thing will fail.

Can we fit this in our ar15 lowers? Just a barrel and bolt/ mag change?

Hey guy's, why don't you see what you can do with the 6x45 wildcat? If you "Ackley" it you can straighten the walls and change the shoulder to 40 degrees. This will let you get more powder in it and increase performance while maintaining the 5.56 bolt and magazines in the AR 15 platform. This might get near 6ARC performance while keeping the round count the same in the magazine as 5.56. If it works out the military might jump all over it!!! You won't need to pay me a royalty just send me an upper!!! 😀

Had to re form 6.5 Grendel brass into 6mm ARC brass, because Hornady doesn't have their shit together. Come on guys, invent a great new cartridge, but then short the market on brass, and charge $3.00 a round for ammunition....? Gotta hand it to you, good way to make some money. I'm almost tempted to just buy a 6.5 Grendel barrel and wash my hands of this mess.....

having watched the progression over the last 2 years yall needcyo go to Florida and set down with Kelly Sanders. You can take his 6mm arc barrels with an 80gr to 90gr bullets and push them in the high 2900 to low 3000 fps and get great accuracy and very low recoil.with lever evolution n cfe223. and shooting sub MOA.. Oh and that's out of a gas gun.

same as jerrbear......where's the brass. I have never seen a piece of Hornaday 6arc brass. it's been all 6.5 G necked down to 6mm arc. And I only have 2oo rounds of the stuff. Thx to Johnny's reloading bench showing how to do the neck down.

Ya now how about ya contribute to barrel materials that give us a barrel that will outlast more than half a case of ammo... Barrel life was never a consideration

Get the availability and the price more competitive and i will build one. A cheap fmj offering would be nice for plinking.

I want to get AR-15 rifle now 6mm much better than the 6.5mm in a Grendel casing 🤔👍🏽🤠 power when I need it My favorite 6mm for DEER 🦌 and 🐗 hunting.

Anybody having trouble with 108 ELDM factory in the lands ? All my 108 ELDM HAND loads seem to be in the lands at 2.13 OCL

Update.... I got a 16" upper from pro2A tactical. It doesn't like the 105 blacks. But, I bought several boxes and have been reloading. It shoots the 103 eldx well with Lever. 58vmax OK, with exterminator. Didn't seem to like 95 LRX. Next up, 80 ttsx for hogs!! Might run 65/75 vmax for yotes.
