Who is Ron Spomer
For 44 years I’ve had the good fortune to photograph and write about my passion - the outdoor life. Wild creatures and wild places have always stirred me - from the first flushing pheasant that frightened me out of my socks in grandpa’s cornfield to the last whitetail that dismissed me with a wag of its tail. In my attempts to connect with this natural wonder, to become an integral part of our ecosystem and capture a bit of its mystery, I’ve photographed, hiked, hunted, birded, and fished across much of this planet. I've seen the beauty that everyone should see, survived adventures that everyone should experience. I may not have climbed the highest mountains, canoed the wildest rivers, caught the largest fish or shot the biggest bucks, but I’ve tried. Perhaps you have, too. And that’s the essential thing. Being out there, an active participant in our outdoor world.

"Flip-flopping" is not a bad thing if it is done because you are thinking, learning, studying and evaluating new information! That is a sign of a person who is wise.

[@CCXRS7]

It's obviously not that anyone just wants a slow .243, it's just how much performance can you shove into an AR magazine length. May be less than most 6mm but it's still more than 5.56 which is the main idea.

[@jmboberg6]

Baffles me that this isn't the main talking point in all these cartridge war videos... It's all about maximizing performance in a given platform depending on the intended application

243 fits in the Ar 10 though....

[@CCXRS7]

@@frankk1512 Yeah, if you have a larger gun with a longer action you can fit a more powerful cartridge. That's like saying the 300 BLK is a "slow 30 cal" because you can fit 308 in an AR-10. It is, duh, but that's rather missing the point of the cartridge.

[@DrewEdwardBacklas]

It pains me to say it because I went 6.5 grendel before the arc existed… but the 6 arc is probably the best all around cartridge for the ar15 platform. It’s a 400 yard deer cartridge you can put in a 6.5 lbs (loaded and scoped) semi auto that shoots sub moa… besides that it has great application as a fighting/defensive rifle cartridge. I think Hornady hit it out of the park with this one. (But Not enough of a difference for me to switch from 6.5 grendel at this point)

[@gbear34]

Same

[@PineyJustice]

6.5 is better, the arc has a very minimal bc benefit while losing 20 grains of bullet. 6.5 grendel and 22 grendel are the best of the bunch.

[@1o1carolina53]

@@PineyJustice perfectly stated

[@DrewEdwardBacklas]

PineyJustice the 123 eldm at .506 G1 out of the grendel can be pushed at around 2450 FPS out of an ar. The 108eldm at .536 can be pushed at close to 200fps faster out of the same barrel length ar. Faster starting velocity and higher bc= more velocity down range in a cartridge class where minimum expansion velocity (around 2000fps for most projectiles) is your determining factor for maximum effective range on game. Your looking at around a 100 yard advantage to the 6 arc.

[@PineyJustice]

@@DrewEdwardBacklas Except that hornady factory 6.5 grendel is more like 2600 fps, on top of that, handloading a little hotter is fairly normal, run a quality bolt. Current pressure limitations are largely due to the old bolts when the cartridge first came out which were little more than modified 5.56 bolts. If you want speed and BC, 22 grendel is better than 6 arc.

[@RazorBrain1]

The 6mm arc was designed for the ar15 platform. It also makes a good bolt gun for deer. SOF wanted a cartridge that could be easily carried like the m4 but had the capability to engage targets over 500m because the bad guys would sit just outside the 5.56 range and lob rounds in just hoping to hit someone. And thus the 6mm arc was made. In the right hands it is capable of accuracy at 1000m.

[@sasquatchrosefarts]

@@RonSpomerOutdoors Ron, you missed something. Although this is good. And 6.5 grendel.is good. Because they run different diameter bolt face, they have heavy upper receivers on ar15. For overall weight of a sporty hunting ar15, you want 300 hamr, or 25-45 sharps. The standard brass can be loaded with good powder and accomplish a lot on a heavier bullet. 6.5 Grendel rifles, and 6mm arc , makes the ar15 gain a pound or two. Which then makes them kinda not such good choices. They are good, but not optimal.

[@dustinfarnsworth174]

The 6mm ARC is one of the most common calibers my customers have built. I went with one of my customers and called some coyotes and he shot a coyote at 580 yards with it. Other than shooting paper, I had never shot the 6mm ARC. I ended up building one for myself and love it. It’s my go to rifle now for coyotes and varmints.

[@ronlowney4700]

🤠 I think many of us out West forget that most of the country is only hunting Whitetail deer and at ranges under 300 yards (usually half of that)! Thefore, what we see as an "irrelevant" cartridge (because we may be thinking about elk) is actually ideal for Whitetail deer at closer ranges! That is why it is important that we take those situations into strong consideration! Horneday seems to be the only manufacturer thinking about what the majority of the country wants and needs, rather than the rare international hunter seeking a stump thumper of a Magnum cartridge! I like what they have done! I think that this cartridge would also be good for the military in closed quarter, indoor combat situations! Anyway, thanks for the review Ron! 👍

[@alexzamora6700]

I think it was initially designed for the military. They wanted something with more punch than the 223/556.

[@TheWarriorsMind]

The 6mm ARC was developed for the AR15. It is a near perfect round for that. If you are a bolt action type person, you would say it is under powered. In opinion, it is near perfect for what it made for. When you compare calibers/rounds, you have to think about why they developed. It is a great round!

[@noelsteele]

There is a bolt action upper for the AR platform in 6mm ARC! It. Is. Awesome.

[@crashdsnowman1]

Hornady just copied the 6mmAR that had been out for 12 or 13 years, 243 and 6mm Predator had also been out several years before the ARC

[@idahoron]

The spot where I believe the 6 ARC will shine is the micro action Howa. The rifle is under 5 pounds. That would make a great high mountain. Off the beaten path kind of rifle.

[@bigald9560]

That's right. That and the Grendel are perfect for those ultralight mini actions. Do you by chance have a howa mini action build? If so would you mind sharing what you used and the weights? Thanks.

6mm arc is just a 6.5 grendel necked down to 6mm. I shoot and load the grendel and I prefer the thump with the 130gr. High bc bullets in the Grendel.

[@hmmm2183]

6mm is just the latest thing to sell more guns and ammo... I would like to see the KZbin industry marketers compare a 100 gr 6.5 Grendel with the 108 gr 6 ARC... All they seem to do is compare the 123 gr 6.5 Grendel with the 108 gr 6 ARC... Surprise, Surprise the lighter 6 ARC is faster.... So it must be better, right... What's the delta? Is it really all that and a bag of chips?

[@DrewEdwardBacklas]

Hmmm Though it’s true the grendel can push similar weighted bullets at similar velocity to the arc, a 100gn 6.5 bullet has nowhere near the BC that a 103-108 6mm bullet does. Both pushed at around 2700 with some pretty warm handloads will do the job out to 250 yards or so but the arc really starts to show advantage at longer range with the BC. I believe it to be sufficient for deer/pronghorn to 400+yards. Grendel shines with a ~120gn projectile on the same game animals out to about 300 but your going to have a tough time topping 2450fps. I own a grendel and don’t plan to switch to the arc any time soon because it suits my need for the ranges I use the rifle at. But when I compare them objectively I do think the 6arc is the superior cartridge in an ar15.

[@hmmm2183]

@@DrewEdwardBacklas True enough because I’ve made the same arguments against the 308 vs the Grendel… And to more effect the Creadmoor … But neither will best the 308 / 5.56 because of government contracts… So while the ARC may have wind / speed advantage because of BC… Is it enough to split the small action market again? Remember both the Grendel and the ARC have same AR bolt issues that the long distance snobs use, when they say “They won’t trust the Grendel’s bolt face, When they tip up the pounder can …”. Is there really enough delta to matter? As you said the Grendel does what you need for the type shots your taking…. My question is still, in a world with 100’s of millions of rifle cartridges no one remembers, why?

[@MrRdvs87]

I went with 6.5 grendel about 4-5 years ago and went that route exclusively to hunt. There’s a good deal of overlap between the arc and grendel that I won’t touch the arc unless it takes off and becomes easy to pick up like it’s a .308 or 5.56.

[@mattcomchoc2957]

agreed. even if you're just getting into guns/hunting and need something in this cartridge range, grendel is still the way to go. ammo is much cheaper and more available, and it's clear it won't be relegated to the dustbin anytime soon, which remains to be seen with the 6ARC.

[@wesfox4455]

Like 6.5 Grendel is easy to find right?

[@MrRdvs87]

It was easier when I first got into it. I was able walk into academy and a few local shops and find decent deer loads for it with relative ease. Since I only use it to hunt, the 6-8 boxes I have on hand will last me a long time. So, unless arc pops up on shelves and is just too easy to score, I’ll keep running what I have.

[@bryanbiltoft8141]

The problem with 6.5G is that you lose enough velocity beyond 300 yards that expanding bullets don't work like they're supposed too.

[@MrRdvs87]

@@bryanbiltoft8141 that very well could be, but hunting in the south east, you’re not likely (there will be outliers) to see distances in excess of even 200. If you’re wanting to sit on a power line and and need to shoot over 300 yards, you might want to select another cartridge.

@@Gieszkanne war always finds a way to happen. I don't think it'll happen anytime soon but decades from now there will be ground conflict between all the super powers. Japan and China will have yet another war, India and Pakistan probably, Turkey and maybe Iran or the Arabs, Russia and someone, and America will probably fight China over Australia and New Zealand or maybe even Hawaii if China is feeling stupid enough.

Think about it. Its got the same, about the same powder capacity as ppc. Ppc is 33 h20, arc is 34 of h20. Powder capacity is one thing that makes poc so dam consistent. It fills the case all the way up. Uses smal rifle primers. Small flash hole. Its going to accurate. Sliw twist or fast twist. Run the powder how ever. If you could get good brass for it. It would really take off

[@PolluxA]

Rumor has it that an 6mm ARC with the steel base of the 6.8X51 Sig can push a 108 grain bullet out of the barrel at 3,100 fps, making it almost on pair with 6.5 Creedmoor. The downside is the high chamber pressure, but that's not a problem if the gun is built to handle it.

At longer ranges maybe, but then your power factor drops enough you need to use a bigger cartridge anyway. I don't get it.

I've spent the last year building what I thought was the perfect AR chambered in 6.5 grendel. Now I don't think so anymore. Dang I guess I found this year's project lol.

[@rjva1743]

Easily one of the top hunting/shooting channels on KZbin. You are very knowledgeable on a wide breadth of many aspects of internal, external and terminal ballistics, even the more arcane details. It doesn't go unnoticed. Well done sir, keep up the outstanding content.

[@Luckiduc13]

Been a fan from the beginning. I hope it continues to grow when the ammo armageddon ends. Love to see more factory bolt guns offering this cartridge as well.

[@sylviahofer1246]

Thanks Ron! My respect for you increased tremendously because of this video. I love the fact that your getting older, and yet you still have an open, teachable mind. Great content. 👍 Moe on my wife's account.

[@Justin-nx5ou]

well done Ron. Thanks for your great insight, as always!

[@johnfife3062]

Great stuff! Thank you. Just for giggles, while we're talking 6mm history, let's look back fondly at the M1895 Lee Navy that fired a 112-gr. round nose 2,560 fps; smokeless, rimless bottleneck cartridge; fast, straight-pull bolt; 5-rd en-bloc clip. The 6mm ARC's better, but not that much better...even after the passage of 127 years. Just imagine what it'd do loaded up with a spirepoint. Some cartridge for its day! Ron, looking forward to hearing your rundown on the 6.8x51 (.277 Fury).

[@georgewhitworth9742]

Well not "straight pull" per say, it was more like a "tilt action" style of bolt, and not a true straight pull.

[@steveelder5306]

the cartridge they made the .220 Swift from

[@miketully9905]

RESPECT It takes a real man to admit when they’re wrong. Kudos.

[@paststeve1]

Great video Ron! One simple mea culpa has added to my already high regard for, and trust in your commentary about new cartridges available today. Thanks for what you do and kudos for your personal integrity and willingness to learn and admit a mistake. Grace & Peace.

[@RonSpomerOutdoors]

Many thanks Rev. Steve. Peace.

[@twissted1277]

I have this 6 arc in bolt action and semi auto. Looking forward to the .22 arc. Thanks for your hard work over the years.

[@ArkansasBadBoy]

I'm so delighted to have run across this video. Back in the late 1980's and early 90's, I had acquired a .220 Swift, .22-250 and a. 243 and loved them all but I felt like I had an idea for an incredible cartridge that I discussed with my father and a gunsmith that mentored me. I literally told them a short cartridge with a shoulder angle that was unlike any others and a little bit longer bullet that could be as little as 50 grain and as high as 120 grain would be my dream cartridge and I was convinced it would be a superb cartridge that also had very little recoil, which would appeal to almost any hunter or target shooter. Believe me when I say I wrote a letter to Hornady with this idea. It was in 1991 before my 22nd birthday. I never heard back from anyone but I honestly assumed that thousands, like myself, sent them similar and same ideas. This video really does put a smile on my face. Good stuff 😊

[@Brian-xplor278]

Thanks for all your efforts over the years Ron. The best thing with the 6ARC has always been the potential... (if)... If brass and factory would open up then hopefully more gas guys would convert and drive demand. Since they go through more rounds, seems quantities would drive more manufactures to chamber bolt guns in 6arc as standard offerings (like 223). Bolts seem to be good enough for targets at the 600-1200 range to practice calling wind & fundamentals, especially for those that are limited to value (and just like shooting distance). I guess we will see :)

[@PineyJustice]

6 ARC 6.5 grendel and the one that hasn't gotten much attention, 224 grendel. All fantastic options.

[@gpdykstra]

It’s nice to see that you did not do just a one and done but you actually followed up on this cartridge. I have had a 6mm ARC for about a year now and I am extremely pleased with it’s performance in taking deer with most of my shots being under 200 yards. Before the 6mm ARC my main go to was the .308.

[@redplemons8084]

I have been doing the AR platform since 1985. This by far has been the most versatile round I have used. I shoot PRS gas gun with it. I hunt with it pig and dear.

[@andyherzfeld9492]

I have one of these little guys as well as a 243, a 240 Weatherby and a 6.5 CM. The 6MM ARC is very easy to shoot well. I haven't taken game with it yet but the 243 and the 240 I have and it was a DRT shot everytime. The 6.5 I got mainly for long range competiton and it is fun to shoot as well.

[@92Ordo]

I like watching this channel because I feel like it's like sitting down with my Grandpa for a history lesson on guns. Thanks, Ron.

[@seanlincicome7328]

Ron can you do a short video comparing the 6mm ARC vs 6.5 Gendel vs 6.8 spc vs .224 valkyrie for deer at 300 yards and under.

[@allihatw]

I love to nerd out in regards to ballistics. You explain this well. Thank you.

[@thomthompson9217]

The 6mm ARC is the round of the future. When selecting a caliber for the next build I go strictly by the numbers; and the numbers for this relatively new caliber outshine everything else in the .243 neighborhood. Big caliber performance, a high B/C, and a respectable velocity make this round a keeper. Additionally, the caliber when married with the compactness of the ar15 platform make this round a huge winner.

[@userJohnSmith]

Big love in this guy. It's faster than it looks and rocks in the AR.

[@travispelletier3352]

Liking this channel more and more. Good stuff!

[@mikemelina7395]

Bill Alexander pretty much hit it over the fence with the 6.5 Grendel, but dropped the ball with SAMI and proprietary patents etc. Ever since, people have been trying to catch lightning in a bottle with cartridges like the .224 Valk 6mmARC and everything else. I may be wrong, but the 6.5Gren beats them all out to 1,000yds and the 6ARC eventually catches up around 1,100yds. I don't know anyone who's ever taken that long a shot, but on retained energy and BC, the 6.5 Grendel beats all the other boutique AR mag-length cartridges. It baffles me why manufacturers don't work up more offerings for it. Using Ron's list, Bill Alexander checked all these boxes 20 years ago, with a cartridge that can stabilize everything from 80 grains up to 129-130 grains and do it out of a 2.26" cartridge and do it with more power.

[@crashdsnowman1]

Bill A just copied Arne and his 6.5 CSS.

[@mikemelina7395]

Weren't they working together?@@crashdsnowman1 I distinctly remember Arne's name thrown out there in the development, and wasn't the base cartridge the 6PPC?

[@crashdsnowman1]

@@mikemelina7395Yes, Arne used the 6PPC case, blew out some taper and necked it up years before Bill A started working on the Grendel. Woody at Lothar Walther introduced them when Bill A started asking questions. Arne gave Bill all the info and they started working together but then Bill Trademarked the name and shut Arne off. Same as every other cartridge, someone designs the cartridge and does all the work then someone else steals the design and gets all the credit.

[@thegoodguy729]

When there are more ammo makers in the game and the round is sub $1 per round, I’ll consider building a 6mmARC, but until then, I’ll stick to the Grendel and the .308

[@JohnLee-lr2op]

I'm relatively new to the 6mm/6.5mm world, just now delving into a 6.5 CM last season, but I wish I had paid more attention to the 6mm Creedmoor. For trajectory and energy vs. recoil I am quite impressed with it. The 6 ARC still holds my interest, but I'm thinking only in the way of an AR platform. Thank you for the video and all of the great info!

[@leewithey2014]

Fantastic!!! 🐕

[@themountainraven]

thanks for the info Ron, always good to see the channel.

[@Kycirion]

Besides the heavier bullet weights, this cartridge was specifically designed for the AR15 platform. All the other 6mm/.243 are long action and require bolt action or AR10 sized rifles.

[@johncox2865]

Terrific video, Ron. A real eye opener.

[@BigT27295]

It's a no brainer for deer hunting.

[@armeddiver]

Thank you for the video. I really appreciate you doing the numbers like you do. I am a big 6.5 CM fan boy. I have no idea why, but I tripped across the 6 ARC and started researching and found that it appears to have a lot longer barrel life than 6 CM or 6.5 CM, with [as you point out] very similar ballistic performance. I just built a 6 ARC bolt gun that matches a 6.5 CM bolt gun that I have and I am enjoying the 6 ARC every bit as much as the 6.5 CM. Again, thank you for the video. It helps confirm my personal belief in the 6mm Advanced Rifle Cartridge.

[@matthewmillar3804]

I really like what you said about new cartridges focusing on efficiency rather than top performance. I never thought of it that way. This makes me happy since I've found I'm recoil sensitive. Too bad we can't use the AR platform for hunting up here in Canada.

[@lylewalters909]

I just built a 6ARC. With 24in heavy barrel. I govwith 600 to 700 foot lbs for northern Michigan whitetail. Heck my old 244 with a 95gr SST does a heck of a job on them as well. Great v Ron . Thanks

[@MrSavage170]

Just got done assembling a upper can't wait to try it out

[@timbaskett6299]

The winds of ballistics change in the light of retail sales......the 6.5 and 6mms have made a come-back in recent years, but I expect the .257in (6.35mm) to do the same. That being said, I still would love to take a 16.5in AR 6mm ARC Pronghorn hunting.

[@danielllewellyn5720]

Love your podcast. Just found your You Tube channel with this video. Thanks for all the great info and insights.

[@markfigueroa1681]

Thank you for the thorough information

[@ryanpatton5937]

I love the 6mm arc it does so many things well.

[@hobbyoftheday4017]

This cartridge sounds like a great cartridge to hunt coyotes and deer. I've always wondered why so many people hunt deer with a 300 wm or 7mm mag here in the woods of va, I've never shot a deer past 75 yards. Few people talk about meat loss, I've seen more than a few front shoulders blow to bits by magnum calibers. It's great to see the trend toward efficient calibers and shot placement

[@davidmartin7479]

Great point. Many folks today use much larger than needed calibers to go deer hunting. Being told they need them when in fact shot placement is what is really critical. Not caliber.

[@johnmccarthy6999]

The bolt action 243 Win 1:10 does just fine out to 300 yards with a 108 grain Berger fueled by Retumbo at between 2950 - 3050 fps. The Arc's niche is the AR platform, a few grains less charge, and about 1.5 lbs recoil.

[@WHOTEEWHO]

thanks for the video

[@miketyson8933]

6.8 Western for me!!! It's an updated .270 WSM and the numbers even at long range are VERY IMPRESSIVE! The 6.8 is a short action BEAST that can do about anything and hunt anything!!

[@firemanfostercfd]

The main reason why you would go with the 6.5 grendel is to get 243-like performance out of an AR-15. Get you a grendel bolt action to go with your AR and you got yourself a pretty cool combo that fires the same cartridge.

[@EarlScyoc-km2qs]

Thanks Ron for the information on the. 6mm arc looking for a all purpose rifle for woodchuck to deer and I believe u helped me decide. Thanks again

[@DaveRoberts308]

The sweet spot for sectional density is in that 6mm to 7mm range. SD matters a lot for performance down range (ability to carry energy), which is why you see so many of the new cartridges coming out in those calibers. If you then step back and say that you want a cartridge that fits into an MSR, that leads you to something like the 6.5 Grendel or the 6mm ARC. I chose the Grendel before the ARC made its debut, but the ARC looks quite interesting given that it was developed later and is essentially a refined and necked down version of the Grendel, or some might say a reimagined version of the Grendel. Either way if you want to stay in the MSR platform, these cartridges are really in the sweet spot.

[@mobilegamersunite]

Love the insight 👌 thanks for the knowledge 👍

[@luvtahandload7692]

Good information on the flavor of the month. You should get "Ron Spomer Outdoors" routered into the front face of your, ahem, cartridge board. 😁 Thanks, Ron!

I can't believe he didn't make the shorter action argument 🤣🤣race to the bottom was probably the correct analogy

Great review.

[@mrshort2379]

personally I love the Data and all of the reviews I have heard on the 6ARC. I can't wait to build my first AR-15 in 6ARC. thank you for the content and education on the 6ARC. Now if they could just figure out how to get a 5.56/223 to perform like a 6ARC we would have it made

[@jonathanhoup9988]

Wow. I don’t even hunt or anything. But 10/10 would hang with you Ron. You seem to have really good entertaining food for thought!

[@tyler6147]

Normally I let gun drama go, but I really got bothered by that original article you posted. LOL I guess more than anything THANK YOU for being open minded and willing to learn. This kind of attitude needs to be promoted more in pretty much anything, but especially in the shooting sports.

[@miketyson8933]

Most of us felt the same way when the 6.8 Western came out nobody looked and we all laughed, now realizing its an updated .270 WSM and its a hammer long range! The 6.8 Western is the best round in a short action that hits numbers close to these magnums but not. AMAZING ROUND and the 6.8 Western will most definitely be my next rifle I am building

[@kevinbouldin3107]

​@Mike Tyson shot my 6.8 at a mule deer this year and dropped it in his tracks at 323yds...my buddy was laughing thinking I missed cause he was a hater of the cartridge til we walked up and saw the damage that western did...he bought one later on lol

[@Woodwerks]

Great video!

[@r.markrosquist4842]

I'm definitely investing in this round. Ammo, rifle, dies and components. Very exciting. HOWEVER I can definitely see this cartridge join the race to obsolescence, IF we don't see more ammo and brass options.

[@jeff0nyschuk670]

I have a 6mm Rem,,,It's getting very hard to get shells for,,I've had it since 1976,,It's aMod,,,M55 Tikka,,I've got about 12 boxes of Hornady Super Performance 95gr, red tips,,and shoot very good 👍,

[@tbjtbj4786]

I found 2 boxes of corlock the other day bought both. My rifle really like the 80gr federal loads but I think they discounted them. I have to feed my rifle my wife's rife and the grandson rife. All 6mm remington.

[@jeff0nyschuk670]

Yah,,I used my 6mm rem, on ground hogs back the old days,,No ground hogs around anymore,,So now I use it for coyotes,,With those 95gr Super Performance Hornadys,,They are boasts up from Hornady,,Because, they perform like a 308,,But,,I've got 15 boxes of them 🙄

[@jeff0nyschuk670]

I don't know who decides on what caliber to drop and which to keep,,they don't think before do,,,I have a Remington 722,,it used to be a 222rem,mag,But rechambered it to a 223rem,still shoots very well, The US Army chose the 223 over the 222 years ago,,& the 222rem mag, had 75 yds,more hitting power,,same as the 6mm Rem, got more than the 243,but the Americans decided 243🤪🤣😁🤪

[@nicolascardillo7615]

Can u a video like this for the 22 ARC, now a days u don’t need a super hard recoil n energy (just look how the 5.7x28 has been growing in popularity accurate n easy to shoot that does the job is more then enough. If we need power we can always go for the 7mm PRC, or a 300 W.M.)
