Ep. 012 - 6mm ARC (Advanced Rifle Cartridge)
Вставка
- Опубліковано 30 бер 2022
- On this episode, Seth and Preston sit down with Project Engineer Miles Neville, and Senior Ballistician Jayden Quinlan. The topic at hand is one that we are proud and very fond of - the 6mm Advanced Rifle Cartridge or 6 ARC, for short. The cartridge can stand on its own in a bolt or a gas gun and serves a wide variety of applications. We discuss how the cartridge came to be, initial offerings, as well as match and hunting applications. We hope you find this episode informative and entertaining.

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."
BRASS, BRASS, where's the 6mm ARC BRASS come on already Hornady!!!
It’s all in the form of 6.5 Grendel. Resizing mine right now into 6mm ARC. Extra steps for sure.
Did an ammo seek search, no 6Arc.
@@markmtbrider
6 ark will not survive if availability doesn't change and now.
@@romeolima5339 amen to that. And I really like 6mm arc. Would love to build a 12.5 or 13.9 but not going to unless ammo availability changes
Is it a copy of 6XC?
Built an 18" 6mm ARC in an AR platform and absolutely love it! It has become one of my top 3 favorite cartridges.
How's the feeding? Do you have any of the 24 or 26 round mags???
What’s 1 & 2?
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.
I went with the complete Aero Precision 24" hvy barrel upper. Accuracy is amazing!
@@oif3vetk9 I was very pleasantly surprised by my Aero Precision. I wanted a modernized AR15, by that I mean an improved cartridge over the 5.56 NATO that could use one projectile for CQB/PDW and as a 1 rifle family rifle. Take medium game, carry easy in a truck or on horse.
What I got was that as well as 1/2" 100 accuracy with factory 105 grain for a fair price.
Where in the world was the carbine taught. Dad was issued one in WW2. They gave those out to staff and support instead of a pistol. But that was 80 years ago. Are you 100 and still shooting??? If so you're my hero!
@@michaelvangundy226 The 30 Carbine served from 1942 in WWII, in Korea 1953, in Vietnam until 1975. In a multitude of little conflicts all around the world after that. The talk says issued to staff and support. Audy Murphy and C Carwood Lipton were not support and neither were many of those issued the Carbine. Think airborne!
In the early 70's I carried a model 70, an M2 30 Carbine in MA1 configuration as my secondary weapon because it was small when folded and lite also a 1911. As time passed there were M16's CAR 15's as the secondary.
I believe when you're in close there are worse choices then a well maintained 30 Carbine or the M4.
@@davidmilisock5200
I wasn't arguing the lethal potential of the little 30. Dad said that it was enough to drop a deer in France. They were on a hold. I just wasn't aware they were used past the Korean war. And about my last choice for frontline combat. He ran a wiring jeep around and had radios to relay for the forward observer. He said he could see the front but was just outside of range. So he didn't need a rifle. For me it was the 20 inch a1. But my war was fought from California.
Love the 6mm ARC, Just need more ammo
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.
Thank you!
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!
6.5 grendel brass easily converts to arc, one pass thru ARC Sizing die and trim to legth
@@barryd.thomassr.9156 I do that.. then sell them on gunbroker and buy 6mm ARC brass. I am way too picky to have the wrong head stamp on my brass. Haha
@@barryd.thomassr.9156 That's what I'm doing, you have to size and fire form so it takes a little time if you don't have a back yard you can shoot in.
Just buy the grendel. Better for hunting. Higher bc bullets that are factory loaded. Better accuracy. And cheap ammo exist for 6.5
@@djl5634 Grendel is a fantastic round. Love that one as well. I got into the ARC for better BC on lighter bullets for coyote/ varmint/ prairie dog at range. Also ARC has better velocity on higher BC pills for 800-1000 targets.
Savage 6mm ARC owner here. Love it. Yes on the varmint load.
Please start cranking out more 103gr Precision Hunter!
Hornady needs to push other Ammo makers to put out different 6 ARC rounds.
My thoughts exactly. This cartridge could be forgotten if this doesn't happen.
yes, we need cheap practice rounds
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!)
Sounds like Hornady needs to sponsor your newfound hobby.
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 .
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.
What velocities are you getting out of those two barrel lengths?
Love my 6 Arc! Shooting lasers. Soft shooting hard hitting
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?"
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
There’s ammo all over the internet. Just need to ship it to your house. Unless you live in a commie state or Alaska
For a new cartridge like this, if you want ammo availability, the best thing to have done is to reload for it. IMO
Rookie mistake buying into a cartridge that has only been around for a year. Then it became a dumb decision buying it when ammo was impossible to find/supply chain issues for 2 continuous years.
I just reserve mine for a deer rifle when I need it until things come around. It really is a dream to shoot. All else fails I will get a Grendel barrel
6.5grendel has cheap steel cased ammo available. And Ppu wolf gold and sellior and bellot make cheap brass cased 6.5grendel
Have a uintah precision 6mm Arc love it.. bought 20 boxes fast as i could, easy to reload
ditto
So much information !
6 ARC just another flash in the pan,
King today, forgotten tomorrow.
I'm not biting.
6mm AR has already had a following as soon as Grendel brass came onto market, on top of decades of 6 PPC.
It's already kind of a thing, now standardized from a company who supports cartridges well.
Ammo gets bought ASAP.
I built a gas gun version and used Grendel brass as a starter. It’s been a pain in the ass and occasionally has shot a 1 MOA group, but not with factory ELDM ammo. I’ve been shooting and reloading for years. 6 PPC and 6 Dasher. 30 BR for score. All performed-not this puppy
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.
I hadn’t shot a rifle since the 90’s. Decided to get back into it with an 80% build gas gun. I went with the 6 Arc, 21”. Still building it, but can’t wait to run it this summer.
How'd it turn out?
Definitely an interesting cartridge.
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.
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.

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
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.
Would really love to see Mile's 6arc PRS gas build since it's mentioned in a number of podcast!
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.
Thank you 😊
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.
Its probably the strongest all around cartridge for a AR15. I hope some other bullet manufacturers make 6ARC. All I have seen is Hornady.
Gas gun or bolt?
love the round. Vortex has this same set up and your table looks cheep. Team up and we all win.
Like the cartridge, but they need support from Ruger to go with Savage.
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.
Need that 75gr vmax
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.
Grendel wins.
What velocities are you getting out of that range of barrel lengths?
@@Brimwald I don't have a chronograph so I can't tell you. I do need to buy one, especially since I'm going to be getting into reloading soon.
@@Brimwald6.5grendel gets around 2400fps from a 16in Barrel with 120grn projectiles. I get around 2300 from 130grn bullets. And about 2650 with 110grn ammo.

I love the mild recoil. Having bad shoulders, I can't take recoil higher than 308 anymore. With this, it's the same ballistics of a 6 Creedmoor, and a lite recoil like a 22 magnum is awesome.
Put a suppressor on your 308. It'll take recoil way down. My 308 weighs 6.5lbs with suppressor and scope but recoils like an unsuppressed 223.

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...
Please manufacture more brass. Please.
Question for community. Looking to get back into Yote, small varmint etc... As a youth it was always a 22-250. Do you recommend the ARC or Creed? Will probably do both gas and bold platforms. Great video and thanks in advance. Thanks//
Great cartridge! Needs more support from hornady, and they need to get other manufactures on board, or it will sadly die off
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
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
22 arc would be a sweet wild cat as the 22 creedmoor has shown us
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
Get the availability and the price more competitive and i will build one. A cheap fmj offering would be nice for plinking.
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?
95gr v-max is the only hornady bullet in stock in my country for my grendel.
So it eats mostly lapua scenar ( they sell them in 1000 boxes for less money).
Saving the v-max for living targets.
Gasoline and electrical bills hurts my shooting 😓
My hunting rifle is one of those cz 527 with a 22 inch barrel chambered in 6.5 grendel.
I'm pushing a 120 grain speer gold dot (good luck finding those) very short bullet buy the way using XBR 8208 I'm pushing 2800 fps and its just scuffing the brass head a little bit.
Come on Magpul we need some magazines
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?
Just built my first 6mm ARC
Love it minus ammo availability! Let’s go @hornady
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.
It looks like someone already had my idea about improving the 6x45. It's called the 6mm Mongoose.
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
What barrel length are you running? I have no problem getting 2685 fps (that's my load node) out of a 24" barrel on a AR. I even went to 2705 fps and wasn't close to max load and still didn't have pressure signs.
@@oif3vetk9 you just answered your own question... no1 really uses a 24 inch ar barrel
Let's Go Hornady.
Steve Hornady forced the "Mandate" on his company. HE CAN SMOKE A TURD.
I'll be glad when you start manufacturing ammunition for everyone. Thanks. 👍
@@kenycharles8600 🤣🤣🤣
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.
Looking for another short frame caliber, 6.5 grendel had my attention, looking into this as well.
Without cheap Russian steel ammo going forward I have a hard time seeing Grendel having any benefit over 6ARC so the builds I was going to do in Grendel will definitely be 6ARC now
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.
They are mostly focused on distance shooting if this cartridge picks up you’ll see a lot more offerings. It’s not very popular right now, especially since there’s debatably better 6mm cartridges for bolt guns
I won’t have another one. Too hard on brass
I load 70gr noslers up to 87gr vmax and it’s great on predators but doesn’t have near the velocity you would expect based on factory load data. I’m running and 18” proof and my 87gr vmax are only going 2675 fps. All the factory Hornady stuff is over pressured and it shows on the brass.
Couldn't agree more a 70 80 grain for foxes and I would buy this immediately, or a 6x45 in a 70g hornady missing a trick here
@@varmint_king Weird. 90gr TNT Federal 6.5 Grendel does 2700fps from my 12" Grendel. 87gr should be cooking from an 18" or longer in 6mm ARC with the right powder combo.
We've been shooting 6mm AR for 18 years already, so data for 6mm Grendel isn't new at all.
What load are you running, and what's your gas system length, barrel length?
So I acquired a 6mm arc in savage bolt rifle. According to Hornady reloading Manual the 108 is for a gas operated rifle. What can I shoot in this bolt action safely. I was always under the impression that bolt action could handle more pressure than the ar
AMMO...MISSING IN ACTION (MIA)!
We need more factory offerings. Varmint, CX and tactical
What bolt actions feed arc the best? Cant wait to neck it down to 22.
I'm planning on prairie dogs to mule deer, & black bear. 58vmax 8208xbr?? What load on the 90CX??
Does the 6 arc use one of those goofy type ar47 mags or does it fit a stanag type mag
It would be Great if you could Get into manufacturing Primers so we can buy & shoot more of your products.
Is there any way of getting your guys to push 6mm arc in Australia
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.
I just checked their site because the one guy here mentioned he was shooting a 90 gr CX, they have an 80 gr & 90 gr cx listed on their webpage as new releases.
the latest hornady handloading book lists lower grain bullets.
What factory load offering do you want to see from them?
I'd like to see a load marketed for self defense, my sub-MOA 18" just swaps the optic from a 4-20x45mm to a holographic and goes from a long-range target/hunting platform to a QCB home defense gun
It would be good to have the option of a lighter bullet tailored for the varmeter community. Something in the 3200 fps range.
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 ?
You guys at Hornady need to make a broader selection of commercial ammo. How is the TAP ammo in 6mm arc for hunting ?
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).
Any chance of seeing 6 ARC in the Whitetail or Frontier lines??
What is the ethical capability for Deer? A 90 to 103 grain is large enough. How much energy does it have at hunting distances, 100,200,300, etc.
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.
Still waiting on god damn brass 🤗
6mm arc Were hanging out for rifles and ammo in australia cmon man
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.
Why do you guys always use a 28" barrel for pressure testing ??
I want to load and shoot 6 ARC. But can't find brass to save my life.
Luckily, got a friend who has a bunch of 6.5 Grendel brass. Will probably form up some that way.
Any news on the 7 PRC?
Thinking on buying one in the AR platform but it is in the 16” barrel, what do you guys recommend ? Will it be ok for the range i will be shooting, 400 yards and in
For sure ok for that scenario!
It's Mike Ezell's 6 Grendel......
I wonder how well it would preform with steel core
Have you tried 115gr 7-degree rebated boattail bullets to retain stability as you fall into subsonic velocities? The smaller case sure saves powder over the 40 to 45-grain loads I put in my 6mm Remington for not much more velocity. I'll bet the barrels last longer. No more than I shoot now, and as accurate and cheap as your ammo is in real dollars when corrected for inflation, buying ammo is better than reloading for me at 79 years old.
Can we fit this in our ar15 lowers? Just a barrel and bolt/ mag change?
Yes....
I call it the 243 Winchester Short.....
👍👍👍👍👍👍
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!!! 😀
What length barrel, in a gas gun, is needed, to get the performance of the 6mm ARC?
Guys are running as short as 12.5 and of course you aren’t going to be at optimal length there
My gas gun is 22” excellent performance out too 600 plan to touch 1000 by the end of the year
I’m using a 12.5” and an 18” and am loving it with great performance.
Well, it has about the same energy than 300 blk out of a 11.5 inch barrel so you can choose whatever you want. Hornady recommends 18", I believe.
I'm using a 16".
@@davidmilisock5200 same here have only shot 40 rounds but I’m impressed
According to these folks, 6mm ARC has the maximum recoil that would allow you to watch your target after the shot...oh and you need a 28" barrel.
How about some 6.5 Grendel brass????
Been shooting a .243 for last 50 years, i should slow it down, save my barrel ?
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
I know it is a year later; however, was the .243 ever considered for this application? and if so, what were the deficiencies that knocked it out of the running?
The 243 Win can’t be used in the AR15.
But I could be used in the AR-10. But old cartridges in new packaging does not rifles sell. A lot comes down to the barrel twist too. Standard twist for a 243 is 1/10”, which is great for deer hunting loads, maximum point blank range shooting, but since the 6.5 Creedmoor came out with modern turret scopes and accurate rangefinders, you can lob a heavy bullet supersonicly over 1000 yards. That’s the selling point. The old school 400 yard and in “flat shooting” rifle doesn’t sell anymore.
A lot of the reasons the communists in the country hate the AR-15 so much is gun sales were declining until the AR’s were made publicly available again.
What is the best barrel twist rate for the 18” barrel and Is it a 5R twist 6mm ARC
SAAMI twist rate is 1:7.5, and that covers the available bullet selection pretty well.
@@milesn3173 thank you
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)
