6mm ARC vs 5.56mm- Side by Side Comparison

6ARC is getting a ton of attention right now as the ideal DMR caliber but I'd like to see exactly how it performs vs 5.56mm in real world conditions. Lets shoot my 14.5" 6ARC upper and 14.5" 5.56mm uppers out to distance and gather hard data on the differences in bullet drop, windage, energy on target, recoil, ability to spot impacts and anything else I notice as a shooter. If you're into shooting medium to long range with a small frame AR, stick around as I know you're going to enjoy this video!

[@Mr.Killswitch]

Love that you show the actual chrono speeds from your guns instead of guesstimating with box speeds. Knowing your actual velocity and the BC’s of those rounds directly backs up the results we saw at distance. Great video!

[@MountainsMulletsMerica]

Yep if you're going to shoot at distance with any level of confidence you have to know actual bullet speeds out of your particular setup..... box velocity is nice but should only be used for getting you a rough idea of what to expect out of a bullet/ caliber. Thanks for watching!

Great video as usual! 5.56 was really surprising here. Both performed very well considering the ranges and wind.

[@cdownslsa]

Great analysis at the end! The main thing 6 ARC brings to the table is you can have that ~10% higher hit ratio over the 5.56 without needing a new gun. As you said, you can just perform the “long range equivalent of a pit stop,” and swap out the uppers when you want to push to 800 or beyond plus have the “x-factor” of confidence in making hits. Sweet video. The dude abides.

[@Courtesyflush52]

Also worth noting that other than sub 200 yards, 6 ARC basically beats 5.56 in every scenario from a terminal standpoint as well

[@slimshadow1204]

Hey Triple M, I appreciate your video format and the content you target. I have both the 6 ARC in an 18" barrel and the 223 wylde in the 18" barrel and both of them are mid length Gas Systems. I do believe the Arc is a 1 in 7 twist. and the Wylde is a 1 in 9 twist. I have personally concluded that the velocity on impact through the 18" Barreled 223 wylde (using only 1 type of ammunition, 69 grain Sierra Matchking) is combat effective PUSHING it at 650 yards, while still maintaining minimal adjustments for moderate wind which for such a light round is comfortable for me. 800 and out as I have suspected and now seen from your documentation and commentary that from that round, becomes more of a lob with significant reduction of energy on target and less reliable... not so great for wound cavity, but good for the occasional gee wiz attempts. I built my 6mm Arc to further my Combat effective range outside of that 650 for "CE" range. I have had to take pause on dialing in my ARC due to situational incapability of finding the ranges needed to shoot that system. So your information regarding 6 arc (though it be a 14.5" barrel) I find very useful. I enjoy your content, so I happily wave to you as your southern neighbor! Keep it up good sir!

[@Jenni_Yimmi]

The wind drift and drop are very similar with 18-inch barrel 6 ARC and 6.5 Creedmoor at 1000 yards

[@LRRPFco52]

@@nedkarp8468 You’re able to maintain your sight picture with the 6.5 Grendel, but impacts are much louder with 123-130gr than 105-110gr. I’m able to hear 6.5 Grendel hits easier than 6mm Dasher once you get out to 600+ yards. If you shoot the 107gr SMK or 110gr PPU FMJ in 6.5 Grendel, you get the same experience as 6mm ARC, but with a little more wind drift. 123gr and 130gr smack the steel harder and give you that satisfying feedback, whereas the lighter bullets are just too anemic for my taste. 5.56 is just a non-player in that space, no matter what you do to it, even if you single-load 90gr SMKs and Bergers. It will hit, but it’s just too hard to hear with a full value wind over 5mph, at least for me. I wear Sordins, so I can hear better with them than without. With 14.5” .308 and 6.5 Creedmoor, you lose your sight picture and need a spotter to tell you where your point of impact was for both misses and hits, but when you connect, it’s very audible. 168gr SMK sounds very similar to 123gr 6.5mm impacts, even from Grendel. 175gr SMK hits a bit harder and you can hear that as well. 140-147gr 6.5mm hits really hard, even giving you nice audible impacts at 1000yds, but so does 130gr 6.5mm from the Grendel, which you can spot your own hits with. The amount of carrier mass slamming back into battery with the large frame AR-10s really messes with your ability to track your sight picture and spot for yourself, on top of more muzzle climb and torque. With the larger bullets in 6.5CM and .308 especially, the scope torques to the left significantly, especially if you have a lighter blaster. You can see it every time someone breaks a shot by looking at their magazine wagging underneath the rifle, even in the prone bipod-supported with rear bag. External ballistics favor the 14.5” 6.5CM for sure, but the penalties have to be considered for your overall experience. You can mitigate the muzzle climb and recoil with 6.5CM if you shoot 107gr, 123gr, or 130gr. I personally love the 130gr VLD in 6.5CM and .260 Rem over the 140-147gr class due to trajectory and lower muzzle climb. 107gr is almost recoilless, but you suffer from the lack of audible impacts again like a 6mm Dasher at the intermediate-to-long distances. In the end, the 6.5 Grendel is the Goldilocks again.

[@billcarlson852]

You had a fair comparison. You make GREAT VIDEOS... YOU SHOWED GUYS THAT 5.56 IS MORE GUN THAT THEY...KNOW HOW TO SHOOT. SCOPE MAKES A WORLD OF DIFFERENCE. .. KEEP UP THE GOOD WORK...

[@jaydeveas2930]

Learned so much! 77gr. 5.56 is impressive. Maybe I don’t have to rush out and build a 6mm ARC after all. Now I have to research the external ballistics of the 77gr. rounds. I’d be happy out to 600yards. Hoping to not having to play with transonic 5.56. Thanks!!!

[@MountainsMulletsMerica]

Oh man 77gr 556 is legit! As shown here it’s very capable out to some surprising distance. If you’re going to spend most of your time 600 and in I’d be going 556 myself. Thanks for watching!

[@LRRPFco52]

Depends on whether you like to hear and see your impacts or not. As you can see with this video, it’s very hard to determine your impacts with 5.56 77gr. If you step up to 6.5 Grendel, those doubts disappear because 123gr impacting the steel sounds like 168gr SMK .308 Win., and wind drift is less. Visible impacts with 24” bolt gun .223 Rem hot loads with 77gr right next to 12” barrel 6.5 Grendel 123gr on the same target will show you what I’m talking about. One is a barely visible impact with tiny little “tink”, while the other is a big slap on the steel with an unmistakable impact and splash mark. I’ve been shooting 5.56 since the 1980s, running it through DM courses for decades, and really see it more as a close range cartridge that hits hard within 200-300yds, then runs out of gas really fast.

Love the comparison. Never ceases to amaze me that rounds that look light years better on paper tend to show marginal improvements in practice. Definitely more momentum on target with the ARC but inside DMR ranges 5.56 is enough. I really figured you’d be doubling the wind or more with the 5.56.

[@MontanaWild78]

@@K-bob_45 I would have to agree

[@LRRPFco52]

@@MontanaWild78 You don’t see any practical difference. 20” 5.56 is a waste of barrel for no appreciable benefits at distance. When you shoot 24” .223 Rem hot loads with 77gr next to a 12” barrel 6.5 Grendel on the same target at distance, the 6.5 Grendel smokes it with far more noticeable impacts and noise feedback shooting 123gr. 6mm AR or ARC (6mm Grendel) from a 20” makes a great coyote/varmint rifle, but you can shoot 85-110gr from the 6.5 Grendel just the same a little faster, though the 6mm has slightly better BCs on paper. Your dope is going to be your dope no matter what, so short of egregious wind holds like with lesser-performing .30 cals, it isn’t a big deal from shooter’s perspective between 6mm and 6.5mm. Step up to .224 Valkyrie and it’s the same story next to 6mm and 6.5 Grendel. Can’t hear the impacts well even with 90gr .224”, but it’s very pleasant to shoot and make easy hits with, you just might not know you made a hit.

Softer than a standard soft shooting 5.56. Really a joy to shoot and fun round. I’d like to have it be my all purpose medium game rifle.

What you did in this video was show why the 6 ARC will be the replacement cartridge for the 5.56 within the military. It will not be 6.8x51, that is another story for another day. As for availability I buy all my ammo online. Even though there is only one manufacturer (Hornady) of 6 ARC right now I have been able to find it without issue. Yes, it is more expensive than 5.56, but quite a bit less than what I am paying for 6.5 CM. Thank you for making the video, it was extremely informative.

[@billydanzz]

Amazing vid as always! I'm now confident in the thought that ARC really won't provide any significant advantage over 6.5 Grendel to justify a switch. At least for my shooting abilities and accessible ranges anyway.

[@LRRPFco52]

The 6.5 Grendel is louder on-target and you can basically duplicate 6mm ARC if you shoot 107gr SMK, 108gr Lapua Scenars, or 110gr PPU FMJBT. I know the BCs on the 6mms are higher, but they all suck when trying to hear your impacts on steel at distance until you step up the projectile weight to 123gr or more. There really is a big difference in how loud the 123gr is on steel, but it isn’t as flat-shooting. 130gr VLD and RDF really hit the steel even harder with more momentum. 6mm ballistics are great on paper and inside of the sight picture, but just can’t deliver the momentum on-target, not even from the Dasher. I noticed this at Steel Safari (3-Day Long Range Field Match hiking across 3 different canyons/cliff edges in New Mexico). The 6mm Dasher just doesn’t hit that hard at distance, is hard to see and hear the impacts, even though it is easy to connect with. A shorter 17.6” barrel 6.5 Grendel was louder on the steel at 600-700yds than 25” 6mm Dashers and .243 AIs. 6mm ARC will never be a Dasher.

Just really goes to show that with a competent shooter 5.56 really can handle a lot more distance than people often give it credit for. This was only a 14.5" too which is a good length but obviously not even the most common length(16") so the average AR might even be able to perform a little bit better. I'm kinda surprised you don't have a really good mk12 clone given the kind of shooting you do. That said obviously the 6ARC outperformed it. But for me at least I still think 5.56" is adequate for my small frame needs. I'm interested in seeing more 6arc content though. I'm also interested in seeing more block 2 content ;-)

[@trevorhawkins8757]

My 14.5" Criterion core 556 barrel loves the Frontier 68 grain BTHP ammo. Thankfully it's cheap, too! At 750 yards it's about 6.7 mils at around 2750FPS for me. My favorite gun to shoot by far.

[@PatriotPaulUSA]

Nice Shooting brother! The 6 ARC has Much more lethality at long distance over the 5.56 because of that 105 grain bullet weight.. Pretty much the entire reason it was invented by Hornady and the DOD. Now that the military has adopted the 6.8 as their next cartridge the 5.56 will continue to slowly increase in cost as the years go forward. Right now the 5.56 is Much less expensive. I just looked and 6 ARC is $1.20 a round in bulk for Hornady Black 105g. The SB Ammo 5.56, 77 grain was the cheapest at 90 cents. Personally I would yank my 5.56 barrel and bolt when 5.56 ammo supply is depleted, replacing with 6 ARC. It can shoot 78 grain varmint type ammo all the way up to 108 grain and still works great in close quarters. Once you get some brass built up its not much more cost if your reloading. 6 Arc in 100+ grain projectiles has much better wind bucking and like 400 Ft Lbs more energy downrange. For a barrel and bolt swap its dam impressive when you look at all the data. If you need to hunt its much more capable than the 77gr 5.56 as well on Hogs and larger deer. Just my 2 cents.

Very fun video I love the comparison definitely would choose the 6 ARC would like to see some 7PRC work and also 308 still a die hard for my 308.

[@davidmilisock5200]

You're seeing nearly exactly what I saw. I have a Colt A2 with a 20" barrel, 1 in 7 in a Delta configuration, with 69 Grain Hornadymatch. Making 600 yard hits (as long as the wind is low) is not a problem. However my 16" 6M ARC Aero Precision, 1 in 7.5 with Hornady Black is a bit easier to hit with out past 600 but the energy on target is a substantial increase.

Agreed, I only got into 6ARC when my 77gr 5.56 got tossed all over by a modest wind at 800yds. My friends with .308 and 6.5CM had no issues, now with 6ARC neither do I

Yes, please do a video on a 13.9" or 14.5" 6.5 Creedmoor.

I really love 6mm ARC. I really hope more ammo manufactures make more ammo types available.

[@scotopicvision]

Love to see a video seeing how far you can shoot standing. Especially using your subsonic 300 blackout rifle since it has rainbow trajectory

[@BigDogDaddyD]

Excellent video. I have multiple AR-15s in 5.56, and am looking for my next different caliber. Looking at 6 AAR, 6.5 Grendel, 300 Blackout, 243, etc...

[@fordvg]

I have seen the 6ark shoot out to 1,280 yards on video out there in Washington. Great video.

[@MountainsMulletsMerica]

Was that my first 6arc video by chance? I shot this exact upper out to about that distance my first time out.

Cool video 👍

[@veriest1]

.243 ARC looks so interesting. I've been eyeing it and .277 Wolverine a lot the last few weeks.

[@chadjones7722]

Battlehawk has one of the best prices on the 108 grain 6 ARC right now, free shipping occasionally on the 200 round case. Roughly $250 right now. Going to attempt to reload it in the near future.

[@DeltaBravoOpr8r]

Impressive shooting

Thank you! Sometimes a little luck goes a long ways haha
