The fact it uses a regular 5.56 bcg gives it a chance to stick.

It kills me to see people complaining about companies being innovative and releasing new cartridges. In today’s industry company have to be innovative. The more cartridges and options the better. Leaves options we as shooters didn’t have 10 years ago

Oh heck yeah!!! I'm glad i held off on going 6 arc! I'm all for this, especially with sons on board for making the rifles! I want one as soon as theyre available!

It’s amazing how rife rounds are constantly changing , barrel life would be my only concern Thanks Ray

Oh my stars. This has my attention. We are going to be watching this round for a while. If it pans out, we are going to seriously get a 16"-18" upper. Many thanks.

Thank you! Your Video’s are The Most Informative! Without Being Bias! Keep On Doing What You’re Doing! Thanks Again. U. S. M. C. 81-2011

More choices are always good. I like the variety of ammo you're planning to release. That has been an issue with the ARC, 3 loadings, all basically the same "long range" crap. I haven't seen any bolt issues with Grendels or ARCs personally, but I can attest to them being very temperamental about the gas system and feed ramps. Good luck with the new cartridge. I'd love to see a head to head between this, the ARC, and some other 6mms all in 18" or 20" ARs. Let's get real about the rounds and get away from the 24" "test barrels"

Love this type of stuff. Great video and best of luck to these guys with getting it out to market. I hope they are successful! Thanks for all the fun insider info!

What a great time to be a gun nut! Thanks for bringing us along!

Can't wait to get my hands on this! Thanks Brian!

Great review as usual X-Ring 👍. This new 6mm Max looks like a winner.

Nice work boys!! I have a 224V and a 6.5G ....been holding off on the 6ARC....glad I have. This may be my next build.

I'd like to see a direct comparison with the 6.5 Grendel. B/C drop and drift with the same basic wind conditions and velocity at 1000 or 1200 yd

Great shooting Ray! Thanks for the video!

Thanks Ray for the great video.

Mike knows what is up- its not enough to to just be a fast bullet, its gotta be reliable as well.

oh how I need one , really badly ! THIS IS FANTASTIC!

Reviewing these comments, It appears we have A LOT of Certifiable ballasticians here... Hornady better fire their staff who stole the 6ARC and start interviewing these folk in the comments. Performance looks great!!, availability in components, reloading dies, gunsmiths who know how to build an AR barrel and ammo demand will weigh factor. Ive personally used Starline straight wall 350 legend brass to form a 6x45, alot of work was needed to convert that brass

This is awsome, literally had this exact idea as soon as I saw some 90gr 350 legend loads, pretty cool

I think even still, the lead is a bit buried here. This cartridge is looking to the future of the AR platform. Maybe not the future of weapon systems in general, but the AR itself the way we know it it as Stoner rifle. 6mm MAX has the potential to enhance the lethality of this system exponentially and the real magic comes in how it performs on shorter barrels. Its a solution for the dreaded "its only good to a 100yd's" problem the MK18 presents. If you can have a system that's shorter and lighter but maintains lethality, naturally you'd want that. The bullet choice available with this cartridge is going to make it a heavy hitter in all barrel lengths. But all while not compromising reliability and with less other compromises in general.

Great video .Sounds like a great round .I Will have to get a rifle set up so i can do some testing .Thank you for the info !

Sounds sweet! I'll hold off until the 22 Max is out there. :) Great idea with the 350 Legend case though. :)

I was rolling a joint a heard "5.56 bolt"! You got my attention!😂😂

I like the idea of this cartridge 👍👍👍👍

This cartridge is definitively a winner to some capacity, what is important is that we contextualize use case. Irrespective of nswdg having adopted the 6mm arc. Some of you may be wondering what the value proposition of this wildcat cartridge is, what will allow this to take off, and whether or not this wildcat will fizzle out like other wildcat rounds in the past (224 Valkyrie, 6.8 spc). Fundamentally speaking this round has been able to solve the most pertinent problem plaguing both the 6mm ARC and the 6.5 grendel, which is the extractor failures in gas guns. The purpose of this cartridge IS NOT to deliver superior ballistics over 6ARC but rather, it is to deliver nearly identical ballistic performance while having much greater RELIABILITY in the AR platform. 6MM ARC is a great round... in a bolt gun, the same can be said for 6.5 Grendel. However, both of those rounds have noteworthy reliability issues in gas guns, so much so that I would advise against running either of those two rounds in a gas gun. It's also important to note that whenever you are running a 6mm arc in a gas gun that you need to be very careful with the types of loads you are shooting. This new 6mm max however, has finally come to market for those looking to achieve maximum performance in small frame AR's safely and reliably. Is ammo availability going to be an issue for the 6mm max? For the next two to three years yes, but the question remains are you willing to sacrifice ammo availability for superior reliability, standard ar parts compatibility, and functionality. For many of the consumers in this specific market segment; the answer is yes, as anyone interested in pushing a small frame gas gun toward exhibiting performance reminiscent of a .308 more than likely has some experience with reloading, has already squared away a very solid general purpose rifle, and more than likely has 1000 rounds of their preferred general purpose ammo on hand. Does this new 6mm max cartridge make the 6mm arc and 6.5 grendel obsolete? No, not by a long shot it's simply matter of delineating appropriate use case for each of these rounds. I believe if this 6mm max cartridge is marketed properly, the 6mm arc and 6.5 grendel will be more heavily favoured in bolt guns AS THEY SHOULD BE. With the 6.5 grendel being a slightly superior option for hunting due to its' heavier larger projectiles, and the 6mm arc being the superior choice for competition shooting with a flatter trajectory and wider range of available 6mm projectiles for hand-loaders. The 6mm Max presents itself as a much better candidate for tactical applications with that improved reliability and standard ar parts compatibility. I will most definitely be building out an upper in 6mm max upper for my safe. All that being said however, initial adoption will come down to effective marketing, if that is executed properly we have a winner here boys.

Ray makes it look easy. 😂

Glad to see SOLGW is in on this one. My buddy and I are huge fans of the 6ARC and our gears are always turning and thinking of new better calibers. We had always wondered if a 6mm bullet could be used in a 5.56 case. Will be putting a new upper together for the 6 max.

I can't believe you get so much performance out of basically switching the parent case from .222 Remington to the .350 legend. 5.56 was based off .222 if I remember correctly. This looks freaking awesome! Definitely need to start up a new build for this! Haha!

I went with the 6mmAR which necks down the 6.5 Grendel case. No malfunctions in the AR platform, only draw back is it never caught on since it was an exclusive design. More accurate then most of my bolt rifles.

Very cool and interesting! Sounds like a reloaders dream

i love seeing new cartridges, solving issues and pushing these bullets to the max. I would really like to see this cartridge with some hammer bullets.

Sounds like a winner.

The AR-15 is a 1994 Honda Civic DX of the gun world. Cheap, 25,000 aftermarket parts, and can be modified to your heart's content. Rims, a six-foot tall spoiler, racing seats, a $5,000 audio system, ground effects, engine tuning.... Change my mind.

Mfers beat me to the punch 😂. Was hoping to wildcat this idea later this year. Congrats and hopefully I get to dive in soon.

Great video.

I'd love to see head- to- head against 25-45 sharps and 6mm mongoose. The extra case capacity of the parent case could allow lower pressure powders or avoid compressed loads. That may give it an edge against the other cartridges. But it's only supposition until it's done.

some pretty good numbers qouted @ 4:30 and they say it's from a 20" AR 58gr v-max - 3528fps 85gr speer BTSP - 3015 90gr eld-x - 2826 for those asking how this varies from other 6mm wildcats based off of 5.56 brass, looks like since they used 350 Legend as the parent case, the lower taper and steeper shoulder angle used allow case capacity to go from 27gr to 35gr.

Range looks familiar. (I'm a member there) Thanks for the preview on this cartridge. Might build a stealth MK12 in this.

I had no idea 350 legend was rebated. Seeing the numbers and this excitement makes more sense to me now. I just compared water capacity on the different cases: .223 Rem - 28.8 6x45 - 26.9 6mm ARC - 34.0 .350 Legend - 36.5 6mm Max -35.0 I think this is something worth checking out.

I had wondered about the functionality of a larger diameter case head and you guys answered my questions for the AR-15 platform. Did I miss you mentioning magazine compatibility or is that already assumed because of the 350 Legend parent case? A lot of naysayers here aren’t talking about why many new cartridges fail and some become a 270 Winchester. The first necessary condition is a well defined use case/purpose. The second necessary condition is to actually have something “new and improved.” Many recent cartridges are “better” simply because they’re designed for new bullet designs, longer bullets with higher BC, and faster available twist rates. Third is some serious marketing and manufacturing support by significant market players. That means both firearms and ammo production and availability, plus reloading dies, brass and published reloading data. Then there’s old fashioned timing and luck. Often times trends in competitive shooting sports drive that last part, and changes can be unpredictable.

I am game. This is a whole new world for me. A barrel, an upper and that's it. A dedicated upper and I am good. Nothing wrong with the 22 Nosler as long as Nosler stays in business, I can get ammo. Same with 6mm ARC, ammo isn't too bad, you just have to buy it from who makes it.

Very neat. Using the 350 legend case is genius. I see this working best with longer dmr rifles "20+ And I think 6mm ARC will still remain popular especially with barrels 18" and shorter.

👏👏👏 this is is exciting 👏👏👏👏👏

I think the 6arc would really be popular if the ammo variety was better and priced reasonable. Some cheap plinking stuff and some varmint rounds would probably help. It’s all expensive now but 223-5.56 is a lot cheaper and it is everywhere. Most people won’t spend 30$ a box for a volume shooting cartridge. IMHO. Hopefully this round gets plenty of support and lots of cheap options even steel cased stuff like 7.62 x39 or some hornady stuff. Anything that is 30$ or above someone will just go with something else. 350 legend started cheap but now is higher than the 30-06 or 308 at my local wal mart. Good luck 👍 I like options and hopefully it goes well.

I'm looking forward to 16" barrels. The magazine options for .350 Legend aren't great per se, but if this kicks off properly, I'm sure 25 or 30 round options will come to market.

They are headed in the right direction. What I am looking for is an AR 15 platform 6mm that can push a 108gr bullet at 3000fps out of a 16" barrel. I know it dose not exist yet but that is what I would like.

Looks like a winner - .243 Win. Short done right. Now affordable and available ammo and market support are necessary.

Usually when we hear about a new AR cartridge it turns out to be a hot mess. (I'm lookin at your 22 nosler and 224 Valkyrie) This one seems to have the legs to get it done. It has the speed we were promised with the 22 nosler. It can launch better BC bullets than the 224 Valkyrie. I just hope this one doesn't fall flat like the other two. I REALLY WANT THIS ONE TO DO VERY WELL!!! I have two receiver sets in my safe waiting for a build worth doing.

Oh boy!, just what we needed! Yet another 6mm cartridge.........😂

Sounds good.

Very interesting🤔

I would like to see a 6mm MAX vs 25x45 Sharps, handloaded using the heavy 25 ELDs, 24" barrels with suitable twists.

Curious how this will perform in smaller packages compared to the ARC. ARCS main issue is the market support. Mainly due to it coming out right before the pandemic. Then yes the bolt stuff.

Interesting but really skeptical long term

That look gnarly

Definitely interesting

IMO ammo has to be sold for under $1 a round, otherwise it will be too expensive to shoot (for the general public) in an AR platform. Look at 8.6 blk - its is an amazing round but nobody wants to pay $3/per round EDIT: I just heard the prices....not bad.

nice, can't wait to convert my old 3gun rifle into a 6mm Max

Maybe I missed it, but what was the max saami pressure? How many grains of H4350 can it hold pushing a 105 Berger?

Nothing more deadly than a 6mm Remington,

6mm-223

I love carrying around my 24" barreled rifle

Probobly the best bolt for AR 15 is 6.8 bolt - stil bigger that 5.56, so you can use easy fat cardrige, but stil strong to hold pressure etc.

What's the difference between this and the 6mm-223? Cartridge specs? Case capacity? 20" 6mm-223 getting 3070fps with 75gr Speer HP using Varget.

There's a reason I don't own an AR15 in 6mm ARC, but I own a bolt gun in 6mm ARC. Bolt guns can handle 62,000 PSI with the 6mm ARC. If this was an option when I was looking for a rifle I might have gone with it in an AR15 over 6mm ARC in a bolt gun.

Glad he was honest about the SDs using ball powder. I'm sick of marketing bullcrap. I've never had a large interest in the ARC because of the bolt problem and it's operation envelope so something like this is more appealing to me. I'm also a big supporter of SOLGW However... how is this a significant improvement over the tried-and-abandoned 6x45mm?

Sounds like a 6mm TCU. Siloute world has developed most of the modern day cartridges years ago.

This is cool near 243 win performance from a standard AR... But it will be a barrel burner

Curious to see what the performance will be in bullets weighing >100gr.

Great news!🇺🇲👍

What about a 224 Max with case length appropriate for high BC or heavy for caliber projectiles?

Nice

New cartridges are always welcome. Please teach us about the difference to the 6x45 (from the 60s) and the 6mm-223 where reloading dies are available since many years. Don't want to diminish the invention of this guy but just try to learn what really about his invention is.

THAT is an amazing round.

Nice Rifle! Tell me about it? What Can, and Scope? What brand Barrel is that and length?

Very cool cartridge. What is the max weight & OAL for bullets? Are 110 grain pills out of the question?

Wow...right as I start seeing how popular the 6 arc is, we already have another cartridge that's competing with it...the 6 arc would probably be better in a ak.

Interesting.

🇺🇸

How different is this from a 6mm mongoose? Seems about the same

Seems like if you went with the 103 eld-x at 1.26in itd be pretty pressure sensitive with all that bullet in the case ...and down on usable volume .

What no one seems to realize is that NOW you can take all the classic 5.56 rifles that are good to 400 to 600 meters and now ream/replace the barrel only and have NEAR 6 ARC performance. Think Steyr AUG in 6 MAX!!! Europeans love 6mm for best overall performance for hunting and target shooting (and war).

I just built a 6 ARC gas gun and converted my savage 110 to 6 ARC. I’m gonna plug my ears and yell loudly through this video. ;)

This is the 6 I can get behind in a gasser

What magazines were you using (brand and were they standard AR-15 5.56 or 350 legend mags)?

so much agree. Eloquently explained exactly why i have held off diving into 6 arc, even though i like it. im in

Any dimensions? How does it compare to a 222 Rem?

Where can I find dies and brass and a 6max upper ?

I want to know what it do out of a 18 inch

I am sceptical, same as for 6mm-223. Light bullet = poor BC, bad long range stability in crosswind. Should have started with 105gr and up, even if at loss of powder capacity

At first I was like, oh no, not another cartridge…. But by the end, I’m thinking about getting a new barrel.

what was the grouping at thousand ?

What shooting range is that?

6x45 has been around from the 70s and is a sized up 223/5.56 to 6mm mad dog weapon systems has 6 mm mongoose same thing sized up brass my 6x45 been a killer rifle for years they just making something that is been around for years

6mm WOA vs 6mm MAX?

Will it never end?

Just what we all need, another 6mm , not

Its basically a 6x45 that they load long to 2.300" (which won't fit in the vast majority of AR15 magazines) to get their velocity numbers and bullet weight up. So unless you want to buy all new mags or window the front like was done with the 6hagar you are loading to 2.260" which will cut down on bullet choices and leave less case for powder. A 100gr bullet is optimistic. Everyone brings up the bolt strength when you open up the bolt face on the AR15 bolt, like with the 6ARC. I say so what. A bolt is cheap in comparison to what even 1k rounds of decent precision ammo costs. If I'm shooting an AR15 I already have spare bolts. Another cartridge that will be forgotten about in short order.

5.56x45mm supremacy

Down in my neck of the woods! Great range isn’t it?
