NEW!! CMMG 6mm ARC Resolute 300 Range Test Part One

[@hornady]

Thanks for checking out the 6mm ARC.

[@yugbe]

EXCITING!! My brother always wanted to see a .243 or a .270 in an AR platform (God rest his soul). I have to get one of these just to honor him, as once again... He had a great idea.

[@Pro-Gunn1952]

Because I can see your Interest in this round in your video! And the build is something that could be duplicated if the proper premium parts are available on the market in the near future. Building a rife as good as the Resolute 300 is just your thing! Bringing us updates on current second amendment affairs and the awesome builds that you put out in your video's keep us all intrigued! I do appreciate you and your channel. Thank you Kotaboy32 for being there.

[@stevenajpvv]

Very cool, I’ll stick to my grendel until this is a little more widely adopted. Thanks for the video!

[@kotaboy32]

Glad it was helpful!

Shooting Grendel to 1000 yards, a 24" barrel make a different, and of course the shooter. kzbin.info/www/bejne/eojXdnWOa5uVrs0

[@fee_lo5265]

I’m actually very interested in this caliber. I usually roll my eyes at all these new calibers but 6mm is where it’s at. It’s perfect for long distance and self defense in my opinion. I bet you can spot your own shots without trouble and get effective terminal performance out to 500 yards.

[@davelaneve2446]

My PRS rifle is chambered in 6 ARC, it performs extremely well in matches. Have also used it on coyotes out to 1450 yards, and hogs out to 800 yards. Drops them in their tracks.

[@Skyhawks1979]

I have an AR in 6mm ARC topped with a Leupold VX-5. Love their CDS system. No more mental math. Just dial the yardage and pull the trigger.

[@jjgriffin3275]

how does that scope work for you? is it dead nuts just dialing for you? what is your zero yardage?

[@JerrBearTactical]

Very cool video KB -32 😁👍... I'm building a 6mm arc Upper just waiting on a few parts to get delivered. I went with a Ballistic Advantage DMR 20 inch Barrel and a Aero Precision Enhanced M4E1 upper receiver with 15 in handguard. Thanks for sharing your experience with us 😁👍🇺🇸👊

[@EagleEyeShooting]

Played around with a 243 LBC. Very similar to this cartridge. Found that LBC to be stupid accurate with handloads using 8208 XBR. This cartridge, now having support will take off. CMMG should have tuned that rifle around that ammo, performance should produce 1/4 MOA. Harells precision tuneable break will dial that in

[@NoGoBu]

My gosh 82nd taught you to shoot, wow 👏 Bravo. 👌🇺🇸🪖

[@kotaboy32]

Lol

[@velocitydreamer]

Did you do a Part Two? Curious if it performs consistently well at 1k yards out of a 16" Or if there'd be strong reasoning for an 18" build.

[@funigui]

or, run a lighter bullet in 6.5 Grendel. The advantage is better mainstream support. Other than that, it's 6 in one-half dozen in the other with the Grendel. Grendel has steel case cheap ammo at least. 6mm ARC can also do really light bullets. im building a 6ARC, but its reallllly close to the same as Grendel.

[@tyler6147]

@Nick Rodriguez Please. Stop. You are displaying your foolishness. 168 grain ELD Match ammo has a BC of .523. Fired out of a 22" barrel it has an actual velocity of about 2600 fps. At 500 the hold over for the .308 is 3.4 mils vs 3.4 mils for the ARC with 108gr bullets. At 800 yards the .308 has a hold over of 7.3 mils vs 7.2 for the ARC. At 1000 yards the .308 has a 10.7 mil hold over vs 10.5 for the ARC. At 1,200 yards the .308 has a hold over of 14.9 mils vs 14.6 for the ARC. Note: The .308 is using actual velocities from a 22" barrel and the ARC is using actual velocities from a 16" barrel. That's an entire 6" less barrel for the ARC and it matches it step for step. If you compare equal barrel lengths of 16" vs 16" the .308 will get 2450 fps velocity and will get smoked every time by the ARC--all while running it a regular small frame AR.

[@tyler6147]

@C-Bomb Hornady didn't start any kind of an argument. They simply stated facts. Like I did above. That 108 grain round has very similar ballistics to a 22 inch barrel 308. It's just factual information that apparently some people don't understand or don't want to accept. Use any ballistics calculator you want and use real world data and post up what you get. In fact that goes for anyone trying to argue about it.

[@JimYeats]

Tyler, I don’t think anyone is arguing that the 308 is the more efficient cartridge. We know it isn’t. I think the point C Bomb was making is simply that it is not an apples to apples comparison. No matter how efficient it is, no matter how accurate it is, no matter how high speed low drag it is, there are simply some applications where a 108gr bullet isn’t going to cut it. If your intended use is to make a setup that is the size of an AR15, have long range capabilities that - out of a 16” barrel - are about as good as a 308, and can still probably kill a man when it gets there...then you are right, the 6mm ARC may end up being your best option assuming it lives up to the hype and also provides good terminal ballistics in lots of real life testing. No one is going to grab a 108gr bullet to go hunt Elk with though. It doesn’t matter whether every box of 6mm ARC comes with a free hand job, a 108gr bullet using the same construction as a 168gr counterpart is not going to penetrate as deeply or reliably through tough tissue.

[@MTCKIE68]

@@JimYeats It's not made to be a big game hunting bullet. But that is coming. Hornady said they are doing some hunting rounds. The purpose of this is less weight than the AR10 with more rounds and better ballistics for the AR15. Better terminal results at 1000 to 1200 yards over the 5.56 with the same life for the barrel. Chill Out Boys !! Stop thinking like Democrats. LMAO !! This is going to be the Best thing for the AR15 platform. Mark My Words !!!

[@InvidiousIgnoramus]

@@JimYeats You're getting pretty hung up on the bullet weight, but this is more on the lighter end for 6mm ARC. Pretty sure it's supposed to scale all the way up to about 140gr.

[@johnparrish9215]

I'm going to have to build a 6mm ARC upper only because the round closely mimics the very old 6mm Lee Navy. It will be fun comparing it to my brothers original Lee Navy on the range.

[@nataliedeyton6829]

I’m really interested in the 6mm arc but will wait and see how it does after some testing. I have a 6.5 Grendel and absolutely love it but with what I saw with the .224 Valkyrie it fell off pretty quickly. But different guns and ammo is never a bad thing 👍 happy independents day everyone 🇺🇸🦅🇺🇸🦅

[@DakotaDoc]

I hear you, and agree. I really think they are learning from the lessons of the Valkyrie.

[@Hunter-eh4pz]

Damn, seeing that makes me excited. I hope the round becomes available, the DOD apparently has been using it the past 2years

[@davelaneve2446]

It's been available for like a year now and is very popular with precision shooters. My PRS rifle is 6 ARC.

[@DakotaDoc]

I fully believe this 6mm ARC is going to do for the MSR platform, what the 6.5 Creedmore did for the Bolt guns. True there are wildcat cartridges in 6mm made from the Grendel (also a great cartridge in its own) and it would have been easy for Hornady to go that route, but if you study the 6mm wildcats, the little extra space the (6mm AR for example) provide, it make the throat shorter and thus harder for longer more slender, higher BC bullets to seat properly and most efficiently. Plus having this SAAMI already with industry support. This caliber has legs and long ones.

[@SuperJlarge]

What exactly did the 6.5 Creedmoor do for bolt guns?

[@tomweaver7723]

Your 2A enthusiasm and the love for your countrymen shows and keep up the good work. We'll keep watching, you keep making the vids. BUZZ

[@Cristopher1976]

Federal brought out the valkyrie didnt they? Also it's been more of chamber and barrel issues than ammo as well I thought.

[@fredmeebley]

That was Federal that brought us the Valk. Hornady has been doing very well with all its recent offerings. It’s a good thing when consumers have more choices, 6.5G is a sweet round for AR, the 6mm is looking good so far.

[@Jerry-dk8se]

Consistent 1/2 MOA with my 20" S.S. fluted BCA barrel/upper, and I know my dope, using 107gr. BTHP, 123gr. ELD-M, and 129gr. SSTs. I'll stick with my Grendel for now. Thanks for the video. 🇺🇸

[@montanawild7558]

I already bought a JP bolt for the 6.5 grendel so I can build a 6mm ARC. I got a 20 inch Wilson Combat Super Sniper barrel in 223 Wylde but I am debating on putting it aside and finding a good 6mm ARC barrel. I should just wait until more companies start offering this chamber. Like Wilson Combat ;)

[@liquid6015]

I love the innovation in the 6mm range we are seeing

[@bcjdwbiernfjherwfbowfib]

What I like about this setup is it is a 1000 yard gun out of a 16” barrel and standard AR-15 lower. Better for long distance than 6.5 Grendel. I like it a lot. Maybe one day...

[@conservativesniperhunter7439]

Great review and awesome shooting big fella . I think Hornady is onto a winner with the 6mm ARC . It will become popular in both ARs and bolt guns particularly for females and younger shooters for PRS matches .

[@autumnfragrance7185]

Think 6.5 Creedmoor... you've been enlightened.

[@frankmiller4550]

Consider ammo and mags, price and availability.

[@BTCAsia]

For your first AR, 5.56/223 makes a lot of sense and is the most economical. The AR-15 lower platform can then be used for several chamberings (22 Nosler, 224 Valkyrie, 6.5 Grendel, 6mm ARC, 300 Blackout) by swapping uppers. The AR-10 platform is bigger and designed for longer cartridges like 7.62/308 and many others. Some parts are compatible across both platforms, some only fit one or the other, and some parts are specific to the cartridge. Generally, the AR-15 is less expensive, more versatile, and spares are more widely available, but they are close. You really need to start by determining your needs, your priorities, and your wants, then look at cartridges and that will determine which rifle.

[@justa3v619]

I shoot a lot of Grendel and I’ve been waiting for someone to do this for a while. The bullet selection is way more than the Grendel and the velocity should be a little better. Ima keep my 12” and 18” Grendel but the 16” is getting a barrel swap to a faxon 18” 6mm arc barrel.

[@Pro-Gunn1952]

Send it Bro! I have been looking and reading about this round! The statistics of the 6mm ARC are incredible! Now you have me wanting an upper in that chamber! But guess what, I'm going to wait and follow your build and copy it! I know your in for it! We'll be watching! Sorry I'm really excited about this round and a future rifle build! Signed, Can't Wait

Very nice rifle. I'm in for a 6mm Arc. wanted a 18 inch barrel but can't find one yet. So based on your video using a 16 inch barrel, I'm going to order it. Now to find ammo here in Kommiefornia. Great video as always! Stay safe and watch your six!!! Reb actual out.

[@AlaskanBallistics]

Great Rifle and Video Man!!! Godspeed to you and yours my brother!

[@SbrGrendel65]

The Grendel has designed with Hunting as its focus but can be great at target shooting. The 6mm ARC was designed for target/accurracy as primary but can also be used Hunting. The ARC is going to take off, but for most that have the Grendel there really isn't a need to switch. Love the Grendel but will be building a ARC. Ordered a Proof barrel will gather parts over time.

[@joyroc885]

This is true. Most people with grendel wont switch over cause of wolf ammo. :) How ever I think 6mm might be a little cheaper to reload for. I have a gredel and love it. I am thinking about building a 6mm arc sbr for I think the ballistics might be better than the 6.5G. Only weak spot for 6.5g and 6arc is reliable mags. Even the known good one can be a hit or miss. Probably only thing keeping me from making it my primary.

[@GunsNBBQ]

Been through Lewistown and Fredericksburg driving truck many times. Nice area down there

[@TheCastleKeeper]

CMMG says it's 10+ weeks out to get a barrel. So if you get your order in soon, you MIGHT have it for hunting season.

[@hunterdan1120]

CMMG has a 20" barrel in their ENDEAVOR line.

[@karenmiller8617]

20in is 2690 fps, 22in 2714 fps

[@ravissary79]

I'm actually impressed that it has a velocity that good in a shorter barrel in light of a BC that high. Like the grendel this is going I really hold its speed well over distance, but unlike it it's going to start out with a lot more speed. Sure it's got less mass, but the 6.8 SPC and 300 blk have great reputations hunting with 110 gr bullets instead of 123s or 130s. And of course 77-110 gr bullets are fantastic on 2 legged critters.

[@FC2ESWS]

If they are using the same 6mm bullet then the one going faster would win.

[@johngordon2929]

In these times i have been watching what is readily a available to this day i have not seen 10mm on the shelves in 4 momths but plenty of .45. And .38 special. My drawn out point is these new boutique rounds might be more avalable due to the less demand. Signed a dummy who now knows to buy in bulk

[@ThisPageIntentionallyLeftBlank]

John Gordon this actually why I’m considering switching to a 6mm round. The demand for 223/5.56 is just too high. If shelves emptied tomorrow, you’ll probably still find 6mm, 6.5, or 6.8 in surplus. Same is true for 9mm these days.

[@videocardzrule354]

Use the Duramag’s 26Rd models. I load all of mine to 20 rounds and never had an issue. I have never tried loading more than 20 in them. Loading 20 is just easy as heck. And saves on ammo as well. All I can say is get some Duramag’s in 6.5 Grendel. Also, some of the feeding issues some people have had is caused by their buffer spring weight apparently.

Just trying to peek through the hand guard watching on my phone, it looks like that 16" barrel has a rifle gas system? Or do my eyes decieve me? Edit: 11:48 I was right! Why are you surprised it runs? Its a different cartridge than 5.56, the 6mm ARC must have even higher chamber pressure than 5.56 if a rifle length gas port placement is optimal for a 16" barrel.

[@kotaboy32]

You're right

[@roncterry]

Actually the 6mm ARC has a lower chamber pressure (52000psi) than 223/5.56 (55000-60000psi). It one of the things they designed in to help minimize bolt lug breakage and extend barrel life.

That’s fine and all but you can run lighter bullets out of the grendel and up your velocity AND increase your range. This is a cool round but the grendel is a proven cartridge.
