The Truth About Carbon Fiber Wrapped Barrels: According To Science

[@vettepilot427]

As a gunsmith, I no longer offer carbon barrels for long action magnum calibers. The only way that I offer a carbon fiber barrel is for short actions up to 300 WSM and only in the heavier M40 (Proof Sendero) contour. We simply have not seen the performance out of carbon barrels in magnum calibers and we’ve tried both Proof and Bartlein. The other issue we see is that carbon barrels will shift point of impact quicker than an all-steel barrel from heat. The issue is not cooling but how quickly they heat up. I think it’s telling that Proof no longer offers the Sendero Light in .30 cal and above. The ONLY advantage that we’ve seen out of carbon barrels is lighter weight. If there were advantages to carbon with concerns to accuracy, we’d see them on benchrest and F-class guns.

[@bradd8383]

[@gk5891]

Carbon added to a light barrel is a good thing. Metal taken away from a barrel and replaced by Carbon, not so much.

The thing about the comp scene is they're burning through barrels and weight is considered a good thing.

[@jeremiahthompson43]

I would like to know more about what you are saying. I'm not too sold on carbon fiber barrels

[@exothermal.sprocket]

"How quickly they heat up" I'm guessing that's due to the significantly reduced volume of steel surrounding that thin steel bore, and the difference in thermal-transfer ability of steel-to-carbon. So basically the steel barrel core gets a resulting higher heat concentration than it would have if it was just steel from the core to the exterior on a standard barrel.

[@alexmills1329]

When I was in school for aerospace engineering I had a professor bring over a solid bar of carbon fiber that was made for use in a helicopter blade, and a sledgehammer. He invited the class to take turns hammering the carbon fiber blank, it was roughly the size of a 2x4 by 4’ . When everyone had their turn and was amazed at the rigidity and strength of that virtually weightless material, he showed us the hammer face with all the marks on it from where the solid carbon deformed that tool steel. This was years ago before they were making barrels out of the stuff and it was amazing at the time to hold something that light and impervious to any reasonable amounts of force.

[@kemosabe53219]

My first and foremost concern is the first shot. I understand the necessity of a follow up shot on occasion but not many are going to shoot more than that. Are carbon barrels more accurate on the second shot, or third in a hunting scenario? Does the weight savings help or hinder the hold? And does that justify the cost? As always, yours and Josephs experience are the reason we watch.

This is very timely for me. Looking forward to this very much.

[@SpudOutdoors]

I have 3 carbon Barrel rifles. All shoot great. No impact shifts or cold bore shifts. When the barrel heats up it keeps the barrel the same heat consistently through because it’s an insulator. So you don’t get cold and hot spots. Just even temp throughout.

[@mikes9759]

Well this answered my question. I often wondered about shooting the bigger calibers with the heat on what metal is left in the barrel. Will be nice for hunting and not carrying a big heavy barrel.

[@hawssie1]

Mine just came in and because I am working with a older Rem 700 action and currently don't have a lathe, I went with the Remage style carbon fiber barrel, which like all remages uses a barrel nut system like savage and allows you to not only install and headspace the barrel yourself with just the always needed go, no go gauges, but you can also make adjustments to say tighten the headspace (within specs) anytime you want, which I guess may or may not be meaningful say if you reload, and find you want to reduce the amount your brass expands in your chamber, a bit more so in other words Its not a one shot deal like custom fit, also you don't have to buy ( or rent) a finishing reamer like a short chambered pre fit barrel.. It's a viable option for any typical Remington 700 action, that aren't built with the specs to pre fit barrels like some modern actions. Now if that Manners stock will come in. ..

[@jameshoff3264]

Where did you get your remage style barrel from? I currently have a remage criterion barrel but I've thought about trying the carbon for weight savings.

[@digginandbuildinwv7012]

I have that kimber in a 30.06, one of the best guns I've ever shot, it's extremely accurate, I shoot hornady 165 sst. Barrel does get hot quicker when practicing but if you throw one shell in at a time and your powder doesn't heat up it'll still shoot accurate for many shots. I've learned it's the powder heat that effects accuracy more than barrel heat.

[@timx1733]

Interesting...yeah, when at the range, I don't chamber a round until I'm on target and just about ready to fire for the reason you're saying. I can get SDs in the single digit SDs in most of my loads. I have not run scientific tests, but it only stands to reason that brass that's allowed to heat up will affect even temp stable powders. I also try to maintain a somewhat stable barrel temp. Easy in cold weather, more time consuming in hot weather.

[@digginandbuildinwv7012]

@timx1733 my neighbor went out to a place in Utah where the guy builds you a custom Long range weatherby and trains you to shoot it, he proved this to my friend and like you said, some of us have proved it to ourselves, I'm going to do a test video running a whole box through at 400yds and see what happens sometime early spring

[@MrMacroJesseSky]

I used to own the same kimber Mountain Ascent you have on the table in 270 (Aka Jeff Coopers dream rifle) At under 5lb it was extremely light. I ended up with a Winchester extreme weather in 30-06. Definitely a heavier (still fluted) profile barrel, but I’d say a far better worry free just works kind of rifle. Especially with a lighter stock than the factory B&C

[@RayTieRom]

Others that have tested heat on carbon barrels suggest that the outside gets cool faster because the carbon does not conduct heat as well as solid metal therefore the inside of the barrel gets hotter faster and cools slightly slower than a totally metal barrel.

[@ManitouGhost]

I have had 3 Christensen Arms carbon fiber wrapped barrels in bold action. 6.5 PRC, 308 and 300 PRC. All of them are sub MOA. Just this last weekend I shot two groups breaking in the 300 and shot a .58 average at 100, 5 shot group. I've only sent about 15 rds through total. All of these have taken pronghorn and some elk and thats why I opted for the carbon fiber, it's light!

[@Paul-k5l1k]

BSF Barrels slide a CF tube over a barrel that is undercut in the area underneath the CF tube so the CF doesn’t touch the steel barrel. There is an air gap between the barrel and the CF tube. The CF tube has ventilation holes to allow air circulation to vent away the heat. You dont want the CF trapping the barrel heat because it is an insulating material. The CF tube butts against a shoulder on the barrel and is captured on the other end by a threaded barrel end piece. The threaded end piece is torqued to put the CF tube in pre-compression. This pre compression puts the steel barrel in pre-tension and makes the barrel very stiff in addition to the stiffness qualities of the CF. Because of the different expansion rates of the steel barrel and the CF tube, the barrel gets stiffer the more the barrel temperature increases. I think this is a well engineered design. Certainly better than wrapping CF in direct contact around a barrel. I shoot my BSF barrel chambered in 6.5 Grendel and have a very small POI change as I heat up the barrel. I usually get a 1” shift up and to the right between the first cold bore shot and the end of a 10 shot string pausing no more than 10 seconds between shots. Best 3 shot group size was .175” and I average 1 MOA in a 10 shot group. I chose a 20” barrel because of the weight savings from the CF and the way the barrel stays cooler during bench sessions and load development. Not bad for a gas system AR in my opinion.

[@eugeneterblanche2024]

Would be nice if you could compare the same barrel without the CF wrapping

[@Paul-k5l1k]

@@eugeneterblanche2024 - An all steel barrel is probably 2-3 lbs heavier. I think the CF sleeve makes the barrel assembly considerably stiffer than an all steel barrel. I would never shoot 10 rounds in less than 2 minutes because of the heat, but the composite barrel stays quite cool. I have some feather weight bolt guns that really open up when they get hot. A 1/2” group will open up to 2” or more so for what its worth I think BSF Barrels is onto a really good idea.

[@jfess1911]

280AI was mentioned several times in this video. Do some barrel manufacturers/ rifle companies that make 280AI barrels use improved "match style" chambers with a section of freebore or do they use the SAAMI chamber? My main concern with the SAAMI 280AI is that it uses the old style 280 Rem chamber which is just a straight taper without a section of tight freebore to assure bullet alignment with the bore.( Ackley left the front of the chamber the same as the parent so an existing rifle barrel could be easily modified to the "Improved" style.) FWIW, just a few years after the 280 Rem was released, Remington switched to the "match style" chambers for all its new cartridges, including the 7mm Rem Mag.

[@GianmarioScotti]

You are spot on about air gaps being very effective thermal insulator. Basically, air gap is the best thermal inulation after vacuum.

[@daftpanda6533]

I think the solution may be that there is a primary source of heat- the chamber. It could possibly create a flow loop like a convection oven- or perhaps an old fashioned pumpless boiler in old houses. Circulation would help to transfer the heat over a greater area, instead of the heat having to transfer it linearly down the barrel, or radiate it away. It's just an educated guess tho.

[@kareldebures7006]

I am willing to seek the truth about this!

[@marklacombe2671]

As a handloader. I can attest to the accuracy node's being wider with the Proof barrel. It was actually odd to me that accuracy and point of impact stayed consistent across charge weights and shot strings. Minded I only shoot 5 shots with a 5 minute cool down and write down my load details and velocities. I am not out slinging 15 or 20 shots at a time. I can say it was shocking how many loads were good in the proof barrel. Testing new bullets and powders it really seems you land on something special pretty easy. Had to rethink what "ok, average, great" for me. Used to be ecstatic to get a .9 inch group. Figured it was as good as I could shoot. Now my ok loads are 1.1inch, average in the .750 and great down in the .4's. It's made nerding out shooting and reloading more fun knowing I can get there more often with this barrel.

[@jfess1911]

That is the point about thicker, stiffer barrels. The vibrations are smaller than with thin barrels and this tends to make them less picky for accurate loads. I have always had a fondness for thicker than average barrels for that very reason. Then again, I don't need to carry them very far, so the extra weight is not as important to me as it is to someone who needs to hike long distances.

[@marklacombe2671]

@jfess1911 yeah I hiked a few miles today with it. That said my old rifle was a heavy barrel. I just couldn't get consistent accuracy out of, or accuracy i could actually get excited about. Was frustrating to reload for. Won't say the brand because I assume maybe it was just a bad day at the factory.

[@jfess1911]

@@marklacombe2671 It's always possible to get a bad barrel, unfortunately. The thicker ones, on average, are more forgiving, but occasionally you run into a "hummer" thin barrel that seems to shoot everything well. Those drive the barrel makers nuts because they still don't know why they those particular barrels are so good!

The nodes can not be wider just because you turn down a barrel and then wrap insulation and plastic less dense, less stiff, that traps heat in the steel.

18:06 on the matter of sleeved barrels, look at a company called BSF barrels. They put a ported CF sleeve over a fluted steel barrel. The ports are ran along the length of the barrel in the same location as the fluting. They claim, i believe, 5% barrel contact and the fluting and ports allow for maximum heat disipation. I have 2 different brand CF barrels, unfortunately not in the same caliber. One is by christensen arms, and the other is a BSF barrel. The BSF holds its accuracy much longer and doesn’t get hot to the touch. The christensen is hot to the touch after about 6 shots

[@jamesmcclendon1203]

Just out of curiosity, what is the life expectancy on carbon fiber barrels? I deal with high pressure cylinders and in the industry there are cylinders that are fiber wrapped. These cylinders have to be tested every 5 years and after the third test discarded (per DOT regulations). And for some reason, we called them bombs.

[@jfess1911]

As far as I know, the DOT regs for fiber wrapped pressure vessels has not changed in over 25, maybe 35 years. They are not very good at keeping up with improving tech. They were in a "this is new, so we will be conservative mode" when the fiber wrapped container regulations were added in the 1980's. It appears that they have not been provided the funding for research and allowed to update their standards for a very long time. The last significant changes in the regs that I recall were well over 20 years ago when they revised some of their shipping codes (yes, I am an Old Fart).

[@TheMrMused]

CF-wrapped pressure vessels are a different beast than a CF-wrapped barrel. The CF matrix isn't under any significant amount of tension on a barrel, which is the cause of CF fatigue on the pressure vessel. The determining factor on a CF-wrapped barrel is the thinner barrel itself being "shot out". The determining factor on the lifespan is going to be the round being shot, the amount the barrel has been thinned, and the number of rounds fired.

[@raivkka4313]

@@TheMrMused quick question, what about that rifle that been stuffed away in the closet for 20 years. Do the CF epoxies break down over time.

@@raivkka4313 Impossible to answer the question without knowing how many extreme thermal cycles the barrel has experienced. (i.e. how many rounds and sessions the barrel has experienced) Unused or with minimal usage and just squirreled away in a closet, that CF wrapping is going to have a lifespan exceeding multiple humans. There's bare minimum hygrothermal (yes, hygro), no chemical, bare minimum thermal (room temperature excursions), no mechanical, and no UV damage being done. Obviously the more the barrel has been exposed to those conditions prior to storage, the shorter the lifespan will be, though exactly how long is extremely difficult to ascertain.

[@kirkboswell2575]

Dead air space is definitely insulation - fiberglass batting, double and triple paned windows, down parkas, etc, and Thermos bottles. A sleeved barrel is going to insulate unless given the Lewis gun treatment. Lewis guns have sleeved barrels BUT they have air ports at either end. The effect is a venturi effect where air is drawn through from one end to the other. Moving air provides more cooling than a perforated cover allowing full exposure to the atmosphere. This effect of Lewis guns provides enough air flow to blow out a candle flame just from air movement. Unless that sleeved barrel provides similar air flow, it DEFINITELY insulates and hides the heat.

[@leeka40]

The one company that I know of that does the sleeve is BSF. They machine slots to let the hot air exchange out.

In my understanding the best (i.e. most accurate) CF barrels are those that cannot TENSION on the steel inner barrel. A Canadian CF barrel maker is one of Thebes at this style of construction. -> Proof Research uses a "Maypole" form of wrap if diagonal, overlapping CF strands. This creates great uniformity of stress on the barrel. . My "fanciest" rifle is a 6.5 PRC Browning X-Bolt Pro. CF stock, stainless steel barrel and action, fluted barrel, bolt and bolt handle, bronze Cerakoted and threaded muzzle with cap and a radially ported brake. IT is sub MOA accurate ONLY FOR THE FIDST 3 SHOTS. Then the barrel begins to heat up and groups open up a bit to 1.25 MOA.

[@AKFF320]

Lost me when you said the carbon fiber pulls the heat put of the barrel 😂😂😂😂

[@dewboy910]

I'm in it for the light weight in a HUNTING rifle. I have no intentions of unloading a magazine in rapid fire with my HUNTING rifle! So any cons due to heat build up is a NON-ISSUE for me. Most often just one shot, but if necessary, 2 or 3 at the MOST. And by the same token, I am concerned only with the accuracy of the first few shots, where number 2 and 3 shots are right with the 1st! It is NOT going to be a BATTLE rifle!

[@buckaroobonsi555]

Guess what? If you took the carbon fiber wrapping off that barrel would be even lighter. If you want a light weight barrel use a lighter profile or shorter barrel.

[@timx1733]

Agreed, but what about a day at the range? I shoot my hunting rifles at the range for load development and practice, and go through 20 - 40 rounds in a day. (allowing the barrel to cool between pairs of shots) If a carbon barrel takes longer than a standard steel tube, that would be a disadvantage to me at the range. Weight is the only advantage I see (well, and cool looks).

[@dustytankersley889]

My little brother has worked at proof research for 7 years. So I had a little suspense for who you were going to say what’s the best lol

[@edwardabrams4972]

I have been saying it for years since the carbon craze that there is no advantage except just a little on the super hot magnums which can made the barrel last a few hundred more rounds before being shot out! I have seen this on the 28 Noslers and the Weatherbys to be true first hand but other then that just give me a great quality barrel on a great action and you have a great shooting rifle most of the time at least for hunting! My short 60+ years of hunting collecting and reloading and owning hundreds of rifles and having several hundred rifles built it’s a waste of money to go carbon most of the time!

[@TeensierPython]

Nah, much better than a sporter barrel. I get far less shift when I twist on a suppressor. And it looks goofy when you put a suppressor on a light-weight barrel. Finally, you have to use thread adapters to even get a suppressor on a light-weight barrel.

[@dontbetreadin4777]

@@TeensierPython Those are all small prices to pay, I love how people who have spent the extra money on a carbon barrel try and justify it with excuses like you've mentioned, no hate, however if they were really that amazing every company would be PUSHING them hard, they dont.

[@LRRPFco52]

​@@TeensierPythonOne of my friends in Finland let me borrow his customized SAKO 75 .308 Featherweight Hunter for several Sniper training and instructor courses there. He had dropped it into a McMillan A4 stock, which had a SAKO TRG bipod receptacle installed in the front of the stock. He had a reflex suppressor that sleeved over that thin tapered barrel, direct-threaded. It was topped with a large IOR Mil scope. Overall weight of the system was very light because of that barrel. At 300m, I was shooting 3cm groups with it. At 700m, I was shooting sub-MOA groups even with an elevation click change. I shot it through several multi-day courses shooting all-day with maximum hand loads of 155gr Scenars in Lapua brass and it just kept holding tight groups and POI at extended ranges. It was by far one of my favorite bolt rifle experiences.

[@nateskate11]

The benefit is that you are getting weight reduction and the stiffness/performance of a heavy steel barrel. I would put my proof barrel in a Sendero contour up against some lightweight pencil barrel any day of the week. Many people stay stuck in their ways.

[@kriswarren6202]

The truth is that not all carbon is equal and the industry is improving every day on Carbon performance. The more they fine tune barrels the more beneficial it is for all of us in price and availability and performance. Hopefully we continue to work on carbon and other light materials for the benefit of all shooters.

[@stephencriswell22]

The only carbon barrel I have is a Is vacortson barrel on my S&W 22 victory and it's a tack driver. But I've never tried to overheat it. Cause it's an expensive barrel.

[@dukedenarie5858]

The only carbon fiber barrel I want is on a dream mountain rifle with a Bat vampire or a kelbly nanook, or something else. (Not sure yet and don’t have the cash lol) chambered in 7 short action ultra mag, probably.

[@clarencehopkins7832]

Excellent stuff bro

[@tythomps]

How's the durability of the carbon fiber outer surface through the brush and such? Just in terms of holding up appearance.

[@mothman-jz8ug]

It cost more so it MUST be better, right? It is so strong that one could even build deep sea diving vessels with it...

[@dalecook4928]

Which is the better carbon fiber gun barrel: Springfield Armory Waypoint or the Christiansen arms ?

[@forrestebert5276]

What is your honest opinion of the Savage 110 proof carbon wrapped barrel rifle in 6.5 or 7mm PRC?

[@edwardabrams4972]

Great barrel not so great of action! They are very accurate but the action is very rough in the Savages on the hundred or so Savages I have owned! If you don’t mind that the Savage is very accurate.

[@heythere4970]

Same opinion as Edward. I have a 110 ultralight in 6.5 PRC and it's the most accurate rifle I've owned and shoots everything I feed it well. But the action is just terrible... It feels like working a metal file against a cheese grater covered in gravel.

[@jfess1911]

@@heythere4970 I have always been impressed by the accuracy of Savage rifles.... but my only bolt actions were Lee Enfields that were ridiculously smooth. I got spoiled. I will probably look at Tikka if I ever buy another bolt gun, unless some one has a better suggestion.

I may have missed it I heard proof which nobody can dispute. I didn't hear Christensen or Carbon 6 which make great barrels as well seamed a little like a advertisement. Im sure there's some other fine barrel makers that I missed. Thanks for the information

[@joshuareed3999]

I recently did quite a bit of research on carbon barrels and talked to many well-known gunsmiths about my project. Every one of them recommended Propf and Bartlein carbon barrels for my purpose- which is a lightweight hunting application. I had suggested Christensen pre-fit for my Remingron 700 action (which is really just a short chambered barrel) but they advised against those. When I actually get my build going it will be with a Proof barrel. Hands down.

[@TeensierPython]

ABS barrels was the first to get a good carbon wrapped barrel. They were bought out by Proof I believe.

[@mistaajones]

brother, please narrate an audiobook or documentary

[@The340king]

The Army did exhaustive research into hand gloves. What they found is that regardless of the thickness of the insulation, the heat loss remained approximately the same. The reason for this is the increase in surface area increases the amount of heat lost even though the transfer rate per square inch was lower. This was around the fingers. Carbon fiber could be doing the same thing.

[@dansaver8247]

I have a shot 'string' of 1, with my old 303 Enfield. No worry about heat mirage after 1 shot.

[@drews.3794]

How was Carbon Six not mentioned? They are the cream of the crop!

[@jamesreese7369]

I worry about the effects of extreme heat on the epoxy glue holding the carbon layers together. That glue has to deteriorate after being heated to extreme temperatures over and over.

[@samesaw]

Yup, carbon fibre strands are an amazingly light stiff material, but we forget that it is all buried together in an epoxy resin matrix.

[@redteam9881]

Love my Christensen Hunter Carbon with the Rem 700 action in 338 Win Mag. I added a Timney Trigger and HS Precision Detachable Magazine kit to it. Had the action glass bedded. Love the way it doesn’t shift impact as barrel warms up. I harvested my 5th Bull moose this year in Alaska.

[@buckaroobonsi555]

So glad you have a detable magazine for your hunting rifle. See a lot of Bull Moose do ya in body armor or hiding behind walls? You see the Moose and say " I better rapidly detach my 20 round mag of 250gr. ELDX and load up 20 rounds of Raufoss explosice/incendiary/armorpiercing/antimaterial ammo!". Carbon fiber wrapped barrels shift more as they heat up it's called science.

[@jacktrout5807]

[@TXLorenzo]

Tanks have been wrapping their barrels with thermal blankets for stability and accuracy for years now.

[@BZE_Fishin]

Do you have any feedback on Fierce Firearms carbon fiber barrels?

[@preyingmathis2517]

Carbon fiber barrels are great for guys that shoot one three shot group a year right before they go hunting and then end up shooting two or three rounds. If you plan to have a range day with a carbon fiber Barrel be prepared to get extremely pissed off to the point that you will think your scope is broken .

[@capt.america6296]

I’ve seen this a few times. L O L.

[@TeensierPython]

I like mine. Nice and light. Stiff enough not to shift when I throw a suppressor on it. I only use them on my hunting rifles.

[@muskyhunter47]

I own a Cooper firearms 28 nosler wirh a proof research barrel. I've been using it for 5 years haven't failed me yet. Would i buy one again ? Probably not just because I really don't need any more rifles . But if a new cartridge came out that i just had to have i would want a proof research barrel.

[@beestoe993]

It seems to me that a carbon fiber wrapped skinny steel tube would act as an insulator and hold the heat in rather than increase cooling. And the fact that the testing mentioned shows the heat extending length wise down the steel tube seems to be affirmation. I could accomplish much the same "stiffness" benefit by simply bedding a skinny barrel the full length of the stock. Bench rest shooters used to do that all the time. Free floating is cheaper and easier, but full length bedding costs a hell of a lot less than a carbon fiber barrel.

[@cfwb3222]

Would love to see you do a comparison of the 7prc vs 28 nosler.

[@702MULEHUNTER]

Do they use carbon fiber berrels in competition shooting .

[@countercivilization]

Very informative thank you! The advantage of bi component technology is rather old knowledge! European in the middle age were surprised to see worriors coming from the steppes with very little bows far out performing theirs huge bows made of wood only ! Imho unless you want the best of the best realistically when hunting the advantages described is the video are rather marginal. But if the price point of those barrels are to go down substantially they might be future !

[@exothermal.sprocket]

So much stuff in the firearms industry is miles into the "diminishing returns" zone. Not speaking for every rifleman, but how many riflemen could say, "I missed my shot because __________" and fill in the blank about the next 100, 1000, or 5000 dollar piece of tech that will bring that bullet another inch closer to the reticle crosshairs? This is the crux of marketing, always promising customers that their money can achieve something that only raw talent can give them. We are already sitting at cheap $500 dollar rifles achieving EASY sub-MOA @ 100yd with cheap everyday ammo.

[@jfess1911]

There will always be a premium market for people who have plenty of money for a slight improvement, real or imagined. Sometimes the improvement is mainly cosmetic. It is what has kept high-end gun makers employed ever since the firearm was invented. Heck, look at how much extra it costs to get just a wood stock with premium grain. Neverthless, even though I am a cheapskate, even I will spend a little more money if I think the improvement is worth it.

[@brian770]

does a carbon wrapped barrel degrade over time? as in my grand dad left me his 50yr old 30-06 and i want to use it . with firearms it is a ligit question, as i do have a lot of rifles from the late 60's that i do use for deer hunting, will my grandkids be able in 60 year to still us the carbon rifle i buy new today? dont really want a rifle with a shelf life.....

[@huntermemmott3039]

I believe Christensen was the first to make a carbon barrel. They came from the aerospace world and were the first to take carbon fiber into the firearm world.
