Does 6mm ARC match 308 performance? Side by side compare

[@jefferyking116]

Shooter is really good here. 6 ARC and 308 are both great but this shooter makes it look easy. Shooting an AR for over 1000 yds in moderate wind is tough.

[@vincentdelaossa9740]

6 ARC was designed to make a better AR15 (M4) without the size and weight of an AR10 in 308. This video does a great job of showing just that. Smaller, lighter weapon, great ammo ballistics vs the bigger and heavier 308. Thank you for the video... hopefully one day the 6 ARC becomes more popular.

[@the.original.throwback]

For many of us old timers, the 6mm vs .30 caliber debate has been hashed out over the years with .243 Win and 6mm Rem vs. .308 Win and 30-06 as the competitors. Accuracy and drop over distance was always similar but for hunting, terminal performance always went to the .30 caliber because of the heavier projectile and energy delivered. Being able to put rounds on target is one thing but putting an animal down quickly made most of us stay with the .30 caliber cartridges for hunting.

[@mylesharvey6488]

270 Win disprove that myth in 1925! Please study ballistics!

Dead on. 6 arc being a smaller package is a pro for it.

[@carpingnyland8518]

Yeah, and when you use terms like DMR, you're talking fighting rifle, not paper puncher. At a 1000 yds, the 6 ARC barely moved the target when it hit, whereas the 308 moved it a lot more. I'd like to see one of Paul Harrell's meat targets out at each range to see what the effect it.

[@Courtesyflush52]

@@carpingnyland8518to its credit, at 1000 yards out of a 14.5 inch barrel, 6mm ARC still has the same energy as a 9mm handgun at the muzzle That’s pretty impressive for a gun that you could use as both a DMR and a room clearing weapon

[@rustyshacklefurd7373]

​@@Courtesyflush52while taking your word for it on energy, I would argue that the 9mm would still do a great deal more damage at point blank range than the 6 arc at 1000 yards. My understanding is that depending on bullet design and several other factors the 6 arc doesn't have enough energy past 500 yards or so to expand or create a large wound cavity. It simply punches small holes at that point.

[@KeterMalkuth]

@@carpingnyland8518 Several points. First off, we all know rifles and pistols act differently. If you shoot someone in the same place with a rifle versus a pistol at close range, the rifle will often drop someone whereas a pistol will not. The primary reason for that is velocity. Not energy on target. Energy on target only becomes a significant factor once you exceed about 2000 FPS, according to the FBI's research on wound characteristics. Below that point, only penetration and to a very insignificant degree expansion or tumbling matter. I make this point because both .308 and 6 ARC will cross the 2000 FPS threshold at about the same distance, that being only 300-400 yards. At 1000 yards, you're talking pistol caliber ballistics either way. No matter how much energy is being delivered, it won't exceed the elasticity of tissue. So it'll just be the wound track itself doing damage. Energy will be moot as long as it can achieve sufficient penetration and especially expand or tumble. As well, that's not even considering the fact that for a DMR, you really and truly don't need to drop someone in one shot. The purpose of a fighting rifle is to eliminate threats. Not necessarily kill. As long as the threat is out of the fight, you've succeeded. I don't know about you, but I don't think I could effectively return fire at 1000 after having been shot, regardless of what I've been shot by. Within 300 yards, sure, a combatant could get lucky and land a wild shot even after having been shot. Both are capable within 300. Past that, the chances of a wounded enemy both being willing to and capable of continuing fighting are minimal. IMO, 6 ARC does what it aims to.

[@gdw1316]

I recently put together a 6 ARC after watching one of your earlier videos. I ended up going with the Faxon 20" match barrel. This thing is an absolute shooter and so much more enjoyable to shoot, in my opinion, than .308. I have a Superlative Arms piston kit coming for the 6 ARC to try and get the gas right. She is a little gassy when suppressed at this point. I have always used restrictive AGB's in the past and wanted to experiment a little. Also, the differences between the AR-10 and AR-15 platforms that you typically have to deal with to go to .308 just make the 6 ARC a better option for me. Also, do a little digging on the interwebs and you can get that 6 arc Hornady Match 108's for about $23-$25 a box (with shipping)!

[@MountainsMulletsMerica]

Really cool to hear you’re enjoying the content and happy with your jump into 6arc! Prior to actually shooting 6arc I was thinking it was all hype….

Like you say, with a little research you can find 6arc ammo for very reasonable prices. Thanks for watching!

I think part of the over gassing issues are because Faxon uses 5.56 logic for their gas tube lengths. As an example, 16” ARC barrels need a rifle length tube whereas Faxon makes theirs with a midlength

Not a fast round (2570 fps avg) but it's consistent. Friend of mine runs a .308 bolt gun and we can share wind calls. Elevation is pretty close as well.

You may be the only channel running a shorter barreled (under 16 inches) 6 ARC, and I love it. The performance out of this round is incredible, definitely the proper cartridge for building the lightest, smallest "DMR" that can perform out to 1,000m.

[@MountainsMulletsMerica]

Man I love short barrels for a couple of reasons..... they are super handy (especially suppressed) and most of the internet seems to think they aren't capable of effectively shooting to any kind of distance. Go to a caliber like 6arc and a shorter barrel rig really is the ideal shooter for 1000yds and in. Stay tuned though....

Being a beginner long-range shooter, for me the lesser recoil allowing me to see the target hits better will help more. The bigger splash of the .308 would also be helpful for spotting misses since i will miss a LOT more than you, but on the east side of the US I'm not really getting that kind of backdrop anyway. Really amazed at what that sort barrel will do. Thanks for highlighting this. (But my other comment still stands, too) I need to seek .308 ammo deals more. I've been seeing almost identical cost but the cheaper rifle components would probably make up the difference over the first 1000 rounds.

I see why you chose the 14.5 vs 20" 308, sure drops are similar. If we are talking just getting hits on target, and a hit is a kill, then the lighter easier to move ARC is a clear winner. Also the ARC carries energy much more efficiently at range, so I would have liked to see the power comparison between the 14.5 arc and a 14.5" 308, or 20" for both. Either way, great videos, keep it up.

[@Courtesyflush52]

They have a similar transonic velocity (1100 yards) so you can compare their energy pretty easily At the 1000 yards he was shooting, the 6ARC will have 400ft-lbs of energy while the .308 will have more like 650ft-lbs. Both are certainly enough to take someone out of the fight

I’ve taken Whitetail and Nilgai (Texas) at 350 yards or so with one shot. I don’t know why more people don’t like it. My “hunting rifle” is a SCAR heavy. I’ve had guides laugh at my set up of ammo and rifle and offer me the use of their “real” hunting rifle…ha. I also have built a 6ARC out of a Wilson barrel. I haven’t shot it yet - we’ll see how it does. I have some of each of the Hornady factory loads - not sure which will work best. Finally, it’s almost like you need to find the windage holdover and THEN start counting hits for results.

First thing I want to say before I get into a comment is, thank you for taking the time to make these videos. I learn a lot from all of your videos, and I really love the comparisons. Now let me repeat a recommendation I made in your video, “Short barrel showdown! 13" XM7 in .277 Fury vs 14.5" 6.5 CM”. I highly recommend you use a shooting mat, elbow pads, and knee pads. If you take the time to get use to them, they will make your shooting much more enjoyable when you are on the ground. If you don’t want to do it for yourself, do it for all us old people that are distracted by thinking about how uncomfortable you must be lying on the ground without those items, LOL. Now that I have made my recommendation, let’s talk about the 6mm Advanced Rifle Cartridge (ARC). My number two favorite cartridge is 6 ARC. My number one favorite cartridge is 6.5 Creedmoor and my number three is 300 BLK. You pointed out many of the reasons why 6 ARC is such a great round and why I believe it will eventually replace 5.56 as the military’s primary rifle cartridge. You mentioned price and I would like to point out a couple of things. If you use Ammoseek.com you can find quality .308 ammunition like Winchester for $0.91 a round. Hornady Black 6 ARC 105gr BTHP can be found for $1.04 a round. I will gladly pay $0.13 more per round for Hornady. I believe that 6 ARC will become the cartridge for the U.S. military’s future service rifle, not 6.8x51 and here is why. The first reason is cost. Right now, Sig has an exclusive contract for a proprietary weapon system, the [X]M7 (MCX Spear). The contract includes all ammunition and all the parts. Something that is not mentioned is Sig’s exclusive armorers training for the new weapon system. Something to note - Sig was awarded a 10 year contract for the new gun in April 2022, but DoD has not dropped the [X] in the weapon designation, which means the weapon system has not yet been adopted, which is interesting concerning all the testing has been completed. The second reason I believe 6 ARC will be the new service rifle cartridge is, Special Operations Command (SOCOM) came to Hornady and specifically asked them to develop and manufacture the 6ARC, which is why I believe that 6 ARC ammunition isn’t any more expensive than it is. The third reason why I believe the 6 ARC will be adopted as the new service weapon is, there is nothing proprietary. Many manufacturers offer complete guns or the parts you need to convert a standard AR15 into a 6 ARC. All that is required is a barrel, bolt and magazine change. Adopting the 6 ARC allows the military to use parts and receivers it already has on hand. Furthermore, the Government can but out an open bid for guns and parts as needed and not be locked into one manufacturer. I have built both a gas gun and a bolt gun. The 6 ARC is superior to 5.56x45, but on the same platform. The 6 ARC mags are lower capacity that 5.56, but nowhere near the weight of 6.8x51 or 7.62x51. Bottom line, an exclusive contract for a proprietary weapons system that really doesn’t offer any true advantage over what the military already has in inventory, just doesn’t make sense. While a superior cartridge that can be used by simply converting the military’s current inventory of service rifles makes all kinds of sense. Just my $0.02. Again, thank you for making the video and allowing me an opportunity to vent my opinion about what I believe [should] be the U.S. Military’s new service rifle.

Where are you shooting? I’m in the northeast, home range goes out to 300. If I drive about 2.5 hours I can get 500, 750 and 1000. Your area looks so nice and open.

[@MountainsMulletsMerica]

Currently located in eastern Washington state. As a guy that grew up on the east coast I realized I landed in a long range shooting paradise when work moved me out here a couple years ago. Appreciate you taking the time to watch!

[@EricSBleicher]

Love your channel, keep up the good work. 👍

Thank you! Really appreciate you taking the time to watch and support the channel!

Great video. Thank you.

[@MountainsMulletsMerica]

Really cool to hear you enjoyed watching this one! Thanks for watching!

[@dkmgm2011]

Great stuff man. Sure appreciate the content.

[@jeffmcmillan6554]

This was an eye opener

[@MountainsMulletsMerica]

In what way? For me I thought the 6arc was way overhyped until I actually started shooting it. After running side by side vs 556 and 308 I’m finding the caliber is living up to the hype!

[@fattigla]

Great video format, but I like both.

[@paulsimmons5470]

20" barrel for 6arc definitely has better ballistics at long range than the 308. It's my new go too. Love it.

[@wildmanjeff42]

very cool video, nice shooting !

[@shootloadrepeat]

Great channel and you're great in front of a camera. The land you're shooting on is amazing and enviable. Is it farmland and how do you shoot when crops are growing? Do you only shoot and make videos after the harvest? Not trying to be in your business, just genuinely curious. Here in Texas there is no public land and anything over an acre is prohibitively expensive, so have to pay thousands a year for a membership to get marginal long range facilities. Plus our weather is terrible. What state are you in?

[@jonathanhoup9988]

More great content from a great channel

[@seanwhite304]

I'd still take 14.5 6ARC over the 308 just because of weight alone . Kitted out 6ARC maybe 10 pounds compared to 13 or 14 pounds of the 308 . For 6ARC is better as DMR 600Y and in . Also its AR15 platform

[@markgraham6127]

Just to comment on you longer barrel on the 6mm ARC bit, my 18" 6mm ARC (in NC) has a 1033y DOPE of 11.8 Mils. Crazy I saw this video today, I just finished a 16" AR10 in .308 (M110A1 CSASS concept clone) build yesterday that I am going to do a similar run against my 6mm ARC tomorrow out to 1200m. Love your stuff. Wish I had your optic budget so I didn't have to scavenge of other rifles! Haha.

[@ConspiracyXClan]

Where are you shooting out to 1200m in NC? Been dying to find somewhere to stretch my builds legs

Would be interesting to hear your thoughts on the 16" SR25

Enjoyed the video

[@paunchouspilot6757]

For those of you who comment regarding down range energy or facing a bear, there is more to life than just hunting. 6 arc is a great PRS round.

[@MountainsMulletsMerica]

Man I should pin this comment to the top! Is 6arc the right caliber for a charging bear…. No but it is a great target caliber which is exactly what I was demonstrating in this video!

[@georgekirby3361]

Outstanding. I need to learn more about this speed drop. Please

[@asullivan50i]

Mullet, your videos are so bright compared to all other youtube content. Any way to dial it down a little? I dont think its your exposure, it just seems like the brightness is turned up. Others please like this message if you agree. Not trying to complain, only trying to help. Thanks for the good content.

[@MountainsMulletsMerica]

Interesting…. What platform are you watching on? I wonder if it’s the HDR filming of the iPhone video doing it. When I check on my iPhone and tv things seem fine but curious what others are seeing or what I can do to improve the image.

[@asullivan50i]

@@MountainsMulletsMerica Im using the KZbin app on my iPad. The quality seems really good, its just very bright compared to anything else I watch on KZbin. I have this issue with all your videos. I usually watch gun videos to lull me to sleep, so it may be more apparent in a dark setting. Anyhow, if the issue is isolated to only me then dont change a thing. I thought others may be having a similar issue and wanted to bring it to your attention. Again, thanks for the content man!

Another Great Video 💯 Thank You 💥💥💥💥💥💥💥💥💥💥💥💥💥💥

[@laevatein8851]

Great content as always. Came from the 36 yard zero video. Your uploads are very much appreciated. Would you ever do a video on barrel twist rate at ELR? Anyways, cant wait for the 5.56 vs 6 ARC video!

[@MountainsMulletsMerica]

Really appreciate you taking the time to watch my videos and support the channel! What do you mean by a barrel twist rate at ELR video? 556 vs 6arc has launched, check it out here: 6mm ARC vs 5.56mm- Side by Side Comparison kzbin.info/www/bejne/ZoTMlmetnLJqrsU

[@laevatein8851]

@@MountainsMulletsMerica Ah watched that one as soon as I finished this one haha. Just an idea but what if you did some comparisons on how twist rates affected accuracy at ELR for a variety of your calibers. Regardless, great content! Learning a lot from your videos.

[@MealTeam6_]

Your videos are amazing! IMO, 6mm out of a 14.5" barrel is perfect.

[@MountainsMulletsMerica]

Thank you! Really cool to hear you're enjoying the content. Tell you what.... this 14.5" 6arc is now my favorite rifle to shoot 1000yds and in. Very little recoil and super easy to shoot make it a ton of fun. I have a feeling you'll be seeing it many more times in future content haha

[@ccrosby1776]

Thank you.

[@tsafa]

I'm most impressed that you're able to make hits at distance in that weird shooting position on one knee. I would fall over😂

[@Solidbuilthomes]

I'd love to see you build a 20" 6ARC and hang 2 ham hocks out at 800 yards then let the .308 and 6ARC have at them.... I think thats when you ll see the true advantage of the. 308.... At those ranges, I definitely prefer power to handiness...

[@Juwan-g8k]

Just great stuff as per usual.

[@bwmalibu1]

Hi I shoot both 6mm ARC 108 Gr match factory Hornady ammo AR-15 and 308 Win 178 Gr federal terminal factory ammo AR-10 both have 24” barrels I noticed very similar drops maybe ARC is 1/10th or 2/10th mils less at 608 yards but this is the limit at my regular range I visit 608 yards
