Thanks for bringing us along to enjoy your hobby and discover something new. I’m really digging this series of videos.

Your videos inspired me to order in a 16" Aero upper and lower in 6MM ARC.

This is a very interesting cartridge! Looking forward to more of your testing

Vertical stringing of your first group is a great indicator your muzzel is jumping before the round fully leaves the barrel. Never seen a back to back comparison with and without a break like this before. Thanks for doing this test.

Great to see its getting worked out. Awesome stuff!!!

*Kotaboy32 Tactical* yes sir that hits with authority, thank-you for taking the time to show us. God Bless.

Its been a minute brother. I'm looking real hard at this caliber. I'm going to wait for the new round growing pains to get worked out first. Anyway great to see new stuff.

Looks good so far I know you'll get it dialed in nicely

Glad to see the asc mags work well.

Good video Kotaboy, long range is addictive!

I never thought I. A million years that a muzzle device makes a difference In accuracy. I'm mainly gonna be shooting 105g Black out of mine . I do have 60 rounds ELD-M. I have another 300 rounds on back order from Midway . Can't wait until my optic comes in .

They can affect accuracy in different ways. Good or bad. It's how they affect the gases that push on the bullet.

Ronnie Smith It’s more than that. For an AR, it definitely helps to control the rifle. In the video, the shooter was getting vertical stringing, which could have been due to not controlling the rifle during the firing sequence. The brake reduced muzzle rise, which reduced the vertical. The second effect is due to changing the harmonics of the barrel. Anytime you add weight to the muzzle of a barrel you will change the harmonics of the barrel.

I just got rounds from Hornady. Waiting for CMMG and Wilson Combat to send me their 6 mm ARC to make a video. Very cool set up video Best Regards

That is a fantastic rifle, one of your best!!

Great shooting! I see that can of EEZOX by your range bag too. I love that stuff!

Really hope this round takes off

Thanks for the video.. 6mm arc. seems to be a winner.

Great shooting you can definitely tighten up with specific loading.

I would put money on that your rest is causing you some accuracy issues also.

Agree 100%. Way to close to the action… fancy fore guard does nothing for accuracy.

Looking forward to the hand loads and getting the calculations all dial in. It looks very promising.

I just happen to come across this again, definitely some vertical stringing there. This is a testament of how important recoil management is. As soon as you put the muzzle break on there is less recoil and your groups shrink and you lose the vertical stringing. With a proper rest you could shrink the groups even more.

My favorite type of video!

So far so good! It look good, the better ammunition should give you the better grouping you are looking for! But overall the test was interesting!

"You can't make the 223/556 rifle any louder....." Hold my beer....

Going to be a sweet build

Very nice, I'll take 2 of em! Thanks in advance.

Thank you.

Kotaboy, you should come up for one of our competitions with that thing and see how ya fair. I would be interested in seeing its performace.

I've watched as many videos and read a lot of information about the 6mm ARC and it's all good. Think I know what my next build will be. Nice shooting!

Welcome Ben!!

Adding/removing a muzzle device changes the barrel harmonics which can change accuracy/poi. I find adding a muzzle device more often improves accuracy in my tests similar to what you saw in your first 2 groups.

Great! Thanks!

I like how energetic that 6ARC is at 1000 yards. Gonna get me an upper with a good quality barrel. My AR-10 .308 is a lot of fun, but it's heavy compared to my AR-15. I'll be able to reach way out there, and not get tired carrying my rifle back to the truck LOL

I'd have to think shooting on bags or a foreward mounted bipod would yield a little better consistency without the brake. I know that's a nice rest you have there and the table probably isn't long enough for optimal foreward clamping but I know you could increase accuracy by changing the setup. Edit: I stopped the video to comment 10 seconds before you said the Arca rail was coming. Very nice.

Nice build & great shooting my breathing still needs work

Great videos on both the 6mm ARC and the 300 Ham'r, how about a shoot-off / comparison of the two rounds.

Barrel harmonics matter. I dropped a 5/8x24 to 5/8x24 adapter between my flash hider and the barrel of my LR308, and it dropped the group size from ~1 MOA to 0.3 MOA.

This is definitely my next build! I think this is An amazing round! I was all set to build a grendel and then Hornady released this round... I want it just for long range target... Can you try it a past a 1000yd? Are there any higher bc bullets available? I wonder if blackjack bullets is making any? Thank you for the great videos

Yes , once adjusted , use holds .

Awsome shooting!

Looking into a 6mm ARC SPR build myself. Thanks for the info!!

Hornady NAILED it with this cartridge, which is very likely the next standard military round.

When I got into the 6.5 Grendel I couldn't shake why not a 6mm (.243). I just wanted a legal for deer AR upper in Virginia. 300 blackout was in impressive.

Im inspired also, waitng on a 22in bbl build on a carbine upper 😊

KB is this the rig that Ray has permanently borrowed? Between the two of you I can see why. It is a very nice set up. 6 ARC has joined the party and it seems that all the boys want to take her out. I feel for 6.5 Creedmoor. She had climbed the mountain and was the darling , and now she's getting pushed aside. Well, I think there is still room for the Creedmoor, but I have to say, I tried the 6 ARC and we got along well. Thanks for the show.

Great shooting

I would've to see this same test with the 6 stc in a custom bolt action

Reloads are the only way to make that dude shine..

Seriously interested in its ability to overcome barriers and how it does in the brush. More about its combat lethality

Your patience is so much better than mine. If my rifle was stringing shots like that I'd be pulling my fucking hair out! Especially after I put a muzzle brake on it and the group tightens up! Grrrrrrr!!!! Hopefully those reloads tighten up those groups!!! Good luck brother!!! as usual awesome video!!!😎😁 I'm going to wait a few years before I jump into 6arc. For me there's just not enough data and components available right now to make it worth my time. I have seen a ton of shity groups from Hornady Factory ammo for the 6arc. Just for fun you should pull one of the heads and weigh the powder charge. I'd be curious to see how much powder they're putting in those cases and what type of powder it is. Waiting for awhile saved my ass on the 224 Valkyrie. Thank God I didn't jump into that mess!

KB, how long is that barrel? Putting the gun specs in the description would be a big help but I know that's probably a pain in the butt. Great shooting brother. I use KB32 discount code all the time. Hope its helping fund your channel!

Such a soft shooting cartridge, I have high hopes for it. With factory ammo are you getting Sub MOA or at MOA? I’m definitely gonna build a 6mm ARC I just need to figure out what barrel I want to go with. At first I was gonna go with a Proof but I’m not a 100% sure about that. For the $ I’m think there might be better options. I was looking at the Stainless version, but who knows 😂

I like to see more or a barrier test with the 6mm arc vs the 6.5G. I have no question that its accurate as most all 6mm and 6.5mm rounds are. The main reason for the 6mm was it was suppose to handle barriers better. I question how much better it will handle barriers compared to 6.5g. Can we make this happen?

Sometimes on a hard surface/bench, the fore-end can jump during recoil. If not this, you have to check the free-floated bbl to make sure that there's no contact being made?... My guess is it's the fore-end jumping more due to more recoil without the brake...

You're good in my books. Go out to 2000 yards dude...

The video quality was great. The accuracy and ability of the round in an AR platform looks to be very over hyped.

I'd like to see the accuracy of some of your target rifles with your hand loads. Should be much better.

Military refuses to wise up and adopt a 6mm AR15 Caliber. Instead they want to go 6.8x51 high pressure in an AR10. So more recoil and less mag capacity all in the name of armor penetration 🤦

At 0.55 shows why I never adjust my turrets and once sighted in at 100 yards I can take it to 1000 yards with no turret adjustments But then my 7mm08 seems to be 1000% more accurate than any other rifle I have ever seen on you tube so maybe that's it LOL Actually it is not that and the fact I never used a scope for like the first 30 years I was shooting rifles made it where when I did get a scope I treated it just like my iron sights of which I would also sight in at 100 yards then shoot a bulls eye at 1000 yards with no adjustments either People on the rifle range would see me do that and comment, WOW you know all about that Kentucky windage !!
