The Real Benefits of Barrel Fluting

Introduction

I have been into precision / benchrest shooting for three years. I am the type of guy who believes in the saying “He alone is educated who has learned the lessons of open-mindedness.” I never hesitate to ask an expert in the field about the art and science of precision shooting. If an answer is not satisfactory, I always turn to technology: The Internet. Dozens of forum sites exist for the sole purpose of educating shooters on this specific subject. From reloading to custom barrel making, the Internet is an excellent source of information.

I have learned so many things about the sport. My knowledge (albeit limited compared to a pro) developed as a result of learning from the old timers at the local shooting range, doing my own research on the Internet, and just from good old trial and error. Most information I hear or read makes good scientific sense. Unfortunately, others are more or less tribal knowledge that have been passed on from one generation to the next. These bits of knowledge are nothing more than misconceptions. In my opinion, misconceptions are like communist propaganda in a sense that the more the masses are misled, the more the people will believe what they hear is real. For instance, the topic of fluting a barrel carries certain misconceptions. Conventional wisdom states that “fluting dissipates heat quicker and it also adds stiffness.”

I would like to point out that I am a Mechanical Engineer with seven years experience. I heard the “benefits” of fluting when I first got into precision shooting, and I have always wondered as to how fluting “increases stiffness.” Initially, this claim did not make any sense to me because common sense dictates that reducing material on anything will also reduce its strength. One does not have to be an engineer to realize this. However, because I was new to the sport at the time I wanted to respect the knowledge of those trying to help me out. I will probably receive lots of controversy on this subject, but I am ready because science and math have my back covered.

The purpose of this article is to shed some light without confusing the reader with a bunch of boring engineering mumbo-jumbo.
Facts

  1. Weight is directly proportional to cross-sectional area. For instance, the weight of the barrel is equal to the cross-sectional area multiplied by the length of the barrel, and finally multiplied by the material density of steel.
  2. Stiffness (rigidity in engineering lingo) is directly proportional to Moment of Inertia.
  3. Surface area is directly proportional to the outside perimeter. For instance, the surface area of the barrel is equal to the perimeter multiplied by the length.

These facts are supported by basic Physics 101 learned by all freshmen engineering students.

Test materials

Savage 10 FP chambered in 308:
Outside Diameter: 0.840 inch
Flutes: None
Cross-sectional area: 0.493 square inch
Area Moment of Inertia: 0.024

Savage 12 BVSSF chambered in 308:
Outside Diameter: 0.840 inch
Flutes: six 3/16″ side, 3/16″ deep, full radius
Cross-sectional area: 0.312 square inch
Area Moment of Inertia: 0.014

Custom Made Rifle / Light Varmint Barrel chambered in 308:
Outside Diameter: 0.70 inch
Flutes: none
Cross-sectional area: 0.312
Area Moment of Inertia: 0.011

Results

12 BVSS Fluted (OD 0.850″) versus 10 FP Plain (OD 0.850″)
Weight: 38% less
Stiffness (as a function of Moment of Inertia): 43% less

The fluted barrel is much lighter, much less rigid, but has much more surface area than a solid barrel with the same overall outside diameter.

12 BVSS Fluted (OD 0.850″) versus Light Varmint (OD 0.700″)
Weight: Same
Stiffness (as a function of Area of Moment Inertia): 25% more

The fluted barrel is much more rigid, and has much more surface area than a solid barrel of the same weight.

Additional Analysis

Deflection at the Muzzle

If you are still not convinced that fluting DOES NOT increase stiffness, I offer the following theoretical explanation.

Let us take all three barrels and place them horizontally in such a way that we permanently affix one end to a fixed position and the other end will basically be free-floating. In other words, let us say that we are welding the threaded end of the barrel to the side of an M1A1 Main Battle Tank. Let us say that the weld is so strong that it is impossible to break the connection. Now, let us say that we will exert a vertical force of 500 pounds at the muzzle of the barrel. So basically, the threaded end is fixed to a tank while a 500-pound man is standing at the muzzle of the barrel. Do you want to know how much the muzzle end will deflect?

The 10FP (non-fluted) will deflect 4.4 inches. The 12BVSS (fluted) will deflect 7.5 inches and the Light Varmint will deflect 9.5 inches. Enough said.
The Ridged Roof Analogy

Others may refer to the ridged roof example. Basically, the argument is that if you take a plane sheet of metal and bend it as to make several ridges, the overall strength of the metal sheet will increase. Therefore, the argument goes on, if you close the ends of the sheet of metal forming a cylinder, the overall strength of the ridged cylinder will also be stronger than a plain sheet of metal that is also formed into a cylindrical configuration. And bingo, based on this analysis, it is assumed that fluting a barrel is similar to adding ridges to a roof.

It is true that adding ridges to a plain sheet of metal will definitely add strength. The reason being is that the Moment of Inertia of a ridged sheet has increased simply because for this type of configuration (flat and not cylindrical) the Moment of Inertia is a function of the overall width of the material. Simply put, a regular sheet of metal has, let’s say, 1/8th of an inch. With the ridges added, the overall width is now at least 1 inch, depending on how the ridges are folded. The higher the overall width of the sheet, the higher the strength. So once again, adding ridges to a flat sheet of metal will strengthen its property.

But if you take a ridged sheet of metal and a plain sheet of metal and reconfigure them into a cylindrical shape of the same overall diameter, the Moment of Inertia will now be a function of the radius and not as much as the thickness. The stiffness of a ridged versus plain sheet of metal formed into a cylinder is not much significant. Moreover, fluting a barrel means removing materials; ridging a plain sheet of metal is NOT removing material but just altering the configuration. Therefore, the ridged roof analogy does not hold water because it is not an apple-to-apple comparison.
Heat Transfer

Get ready to be blown away. There is another misconception about fluting in relation to cooling the barrel.

Some people believe that fluted barrel cool off faster than regular barrel because the surface area of a fluted barrel is greater than a plain one. I am sorry to say that this is absolute fallacy. Fluted barrels indeed cool off faster than a plain barrel of the same diameter, and not because of surface area, it is because of other factors.
Here’s why:

Let us say you fire 10 rounds in 10 seconds in a hunting rifle. And at the same time your friend also fires 10 rounds in 10 seconds in a bull barreled varmint rifle. We all know that heat is generated as a result of the bullet going through the bore at a high rate of speed, causing friction and releasing energy. Now, the temperature inside both barrels should theoretically be equal, but the temperature on the surface of the hunting rifle will be a lot hotter than the temperature on the surface of the varminter. It is because the wall of the hunting rifle is a lot thinner than the wall of a varminter. The closer you are to the heat source (the bore of the rifle) the hotter it is on the surface of the barrel. Makes sense? In essence, the thickness of the barrel acts as an insulation. In short, the thinner the wall, the faster the heat reaches the surface and the faster the heat will be dissipated into and equalized within the ambient (outside) temperature. This type of heat transfer is called conduction (the other two are convection and radiation).

Here is an excellent analogy. We love to barbecue in the summer. Place an aluminum foil on the grill to cook you burgers. After you burgers are cooked, remove the aluminum foil and notice that it cools off almost immediately. Now fold the aluminum foil to make it thicker and put it back on the grill. Remove it afterwards and you will notice that it does not cool off as fast. It is the same analogy with barrels. In short, hunting rifles dissipate heat quicker than varminters do.

So how does fluting aid in heat dissipation? Basically, as materials are removed the flutes become closer to the bore. So when the bore gets hot after firing several rounds, the heat generated reaches the surface of the flutes a lot faster than a plain barrel of the same diameter.
Conclusions

In conclusion, a regular plain barrel is a lot stiffer than a fluted barrel of the same outside diameter; however, a fluted barrel is a lot stiffer than a regular barrel of the same weight. Fluting will definitely dissipate heat quickly. And it is not because the surface area is increased; it is because the heat is allowed to reach the outside temperature at a faster rate by removing materials. If your bull barrel becomes unbearably hot on the surface, it is safe to assume that the bore temperature is at a point where it can literally dissolve soft materials. This will damage your bore in the long run.

So if you wish to flute your barrel, it should be because you want to reduce the overall weight of your rifle and you want your barrel to cool at a faster rate. Fluting your barrel with the belief that it will add stiffness just doesn’t make any scientific sense.

Calculations

A) Moment of Inertia of Circle:
Figure 1. Barrel Cross Sectional Detail

I = [p (r ^ 4)] / 4

Where
I = Moment of Inertia
R = Radius
p = pi (3.14)

Note: Moment of inertia of the caliber (.308 in) was subtracted from overall moment of inertia.

B) Calculate Deflection of Barrel at Muzzle
Figure 2. Free Body Diagram of Barrel

Y max = [-P(L^3)] / (3EI)

Where

Y max = maximum deflection at free end
P = load exerted at end of barrel
L = Length of barrel
E = Modulus of Elasticity (28 x 10^6 psi for steel)
I = Moment of Inertia

C) Calculate Heat Transfer from Bore to Surface of Barrel
Figure 3. Rate of Heat Transfer Diagram on Fluted Barrel

qr = [2p Lk (Ts1- Ts2)] / [ln(r2/r1)]

where

qr = rate of heat transfer
L = length of barrel
K = thermal conductivity, which is constant for steel irregardless of overall diameter
Ts1 = temperature inside bore
Ts2 = outside temperature
r2 = thickness of barrel from bore to surface
r1 = radius of caliber, in this case it’s .154″ (.308 / 2)

The higher the value of the rate of heat transfer (qr) the sooner the barrel’s bore will cool off.

Notes

  1. AutoCad 2000 was used in determining the perimeter and cross sectional areas of the barrels.
  2. Also note that I have a 12BVSS and 10FP in my gun collection which were used in these analyses. The Light Varmint Rifle outlined, while can conceivably be developed, was used to serve as a theoretical example only. I am aware that Savage 12BVSS typically has a 26-inch barrel and 10FP has a 24-inch barrel. However, the 10FP I used in the calculations has a two-inch muzzle brake making the rifle 26 inches in length.
  3. Moreover, one may argue that the 12BVSS is stainless while the 10FP is regular steel. The two materials definitely have their own distinct metallurgical properties; however, the Modulus of Elasticity (which also determines the stiffness) between the two is very close.

Barrel Fluting

I’m planning to trade my 30/06 700 BDL in on a Remington 700 VS-SF in .308. I’ll stick a Leupold Mk4 M3 10X on it with those angled Baer mount & rings. Maybe later on sell the stock & switch over to a UARS stock. Paint it up all ugly and then shoot all summer getting ready for S.M.

Jim,
Dude, take some advice and stay away from the fluted barrel Remington. They are sexy, cool and all of that but I don’t understand why people are so into them.

1. THey make the gun lighter. Bad thing. A “sniper” rifle needs to be barrel heavy it makes your position steadier.

2. Increases heat disapation. Not a problem unless you plan to fighting off zulus and doing mucho rapido fire.

3. They look cool. Despite numerous rumors to the contrary, style points won’t get you over in training

Almost every gunsmith worth a shit will warn you off of fluted barrels for reasons that a gunsmith could elaborate on. These reasons are concerned with stresses on the barrel.

And on the stock, check out the H&S Precision stock line.

In 1994 I ordered a Hart .30 cal. 1:12″ barrel for my .300 Mag. Wimbledon rifle. Soon after I began to have cold feet as far as weight was concerned. We’re looking at about 16 to 18 lbs. total; and I’m only a little guy. Called up one of the Harts and he said that as long as my barrel hasn’t been reamed yet, there would be no problem with fluting. Believe me, the Harts will not flute a barrel if it will hurt accuracy. Their reputation is on the line with every barrel that leaves the factory.

BTW, the fluting they do is by grinding not by milling. When done in the proper order of things, fluting is not harmful at all. And this was before cryogenic treating also.

Just dug up the very first targets shot with this rifle at 100 yds (07/04/94). Light switching wind, overcast. To briefly describe the rifle it is a Hammond’s built, McMillan prone stock, Hall Express action, Jewell 1.5 oz. trigger., 24X Leupold, custom dies, etc, etc, you get the picture.

Mind you, this is day one at the range. With 72.5 gr. of IMR 4831 (128.5 on the Culver) and Berger 190 VLD’s the first two groups were .200″ and .400″; with more vertical than horizontal. Switching to 190 gr. Sierras the next group was .450″. I sure wish that I had only shot 10-shot groups and more of them. But three consecutive 5-shot groups is pretty indicative of repeatable accuracy. I shoot at quarter inch black dot for range work.

The fluting ($90.00) knocked off about a pound, but it is still too heavy for me to comfortably support in a long match. But I’m glad I did it. It would be unusable to me without the fluting.

That’s all for now.

About Barrel Flutting. I have to agree with Gooch. You dont need it on a sniper rifle. Put it this way what is easier to make perfect a round barrel or one with a bunch of slot ground into it? The answer is obvious. Flutting is popular in HighPower Matches because it cools better…. Now that is done by custom smiths and not on an assembly line. How precise do you think remington can do that. Also a HighPower rifle will generally shoot into 1/2 to 1 minute and that is all that is needed to clean. Don’t buy a factory flutted barrel.

Hi guys,
Just my 2 cents worth on barrel fluting. Well not exactly my two, I got it from Boots. Some of the info that he sends out on his price sheet says that he seems to think fluting makes his barrel shoot a little better. I might add however, that no human being could see the difference when shooting it out of the shoulder. He is talking about bench groups. He flutes them before he rifles them, and he can do it on an already light contour unlike some of the others. I agree that the mass market ones, as well as any buttoned barrels that are fluted, should be avoided. I happen to like rifles that aren’t heavy, and they don’t seem to affect my shooting any.

To Flute or not. In the past few years I have owned the following rifles 700 remingtons. I don’t customize other than my own trigger work and accuracy bedding etc.NO professional customizing allowed.
standard hvy bbl .223PSS,308PSS, 220 swift .243v wood stock & another .223police model (one of the first they did.)
and stainless flutted barrels in .223,308,300win mag. (also tested a 25-06 flutted stainless and another .300 win mag that belonged to someone else in flutted barrel. I fired all these for effect and loaded all to best performance I could get. I’ll spare you the details for now but the only thing I
have left is the flutted stainless 700s. Not only do they weigh less
which is an assett as far as my use goes!
All the flutteds shot better than the others and the worst flutted stainless shot better than the best round barrel. I am not suggesting that the flutted barrel is the reason but this is the results I’ve had. Maybe the others can be customized to shoot as good but from the factory this is the way I tested them for what it’s worth and late mod. remingtons are the only thing I’m talking about. It could be the stainless (but that will be challenged) could the twist in some cases but I tried tailored loads. Or it could be that the harmonics are a bit dampened by the nature of the flutted barrel? Roll your own conclusions.

Gooch and Mike: About the flutd barrel. I had a good amount of time to mull over what was said about the fluted and I was going to dance on this keyboard and start to explain all the fluted attributes. But in retrospect, the both of you are absolutely correct that in SNIPER use it only requires one, maybe two shots and not sustained fire where the barrel really heats up. Cold barrel shots are the thing here. Now you really made feel bad and because 1/2 of the barrels I have are fluted. Oh well, live and learn from the logical master of his trade. Mister Gooch, that is why you are the master and I am , well, I guess, the (and I really hate to say this) … the grasshopper.

On Fluting Barrels,
Been there done that!! I’ve talked to more barrel maker’s and gunsmith’s than I care to remember on fluting, and your all right!! (In your own way). Fluting will “NOT” inhance accuracy only decrease weight. If the fluting is done correctly it will “NOT” effect the accuracy adversely. If the fluting is done after machining then the barrel must be cryoed to releive the stress put in it by the fluting.
Most gunsmiths like the fluting because it’s $100 to $150 in their pocket. Unless weight is a “Critical” factor take “MISTA GOOCHS” advice and save your money. Thats why we call him “MISTA GOOCH”!!

Yo,

Is there some disagreement that a sniper rifle should have some weight to it? When I made my post refering to the non-advantage of fluting I stated that a sniper rifle (not a hunting rifle or an across the course rifle) should have some mass to the barrel. Remington recently put out info on the M24TC and seemed to think that it was a good thing that the weight was under 10 lbs. I don’t see it.

When you are shooting from a sling, weight can mentally/physically distress a shooter who can’t handle the weight due to a poor position, lack of resolve or bad mental managment. But when a sniper is shooting from a supported postion such as a ruck sack, bipod etc. the weight of the rifle will help to steady the position and reduce felt recoil and muzzle flip as well as making it steadier during the range estimation process. I have shot lighter rifles such as G3’s, M14’s, M16’s, SSG’s etc that didn’t have the ass that a M40A1 or a M24 has and found the relative lightness to be a distractor. At least that is what I have found.

As far as heat disapation goes, of course a sniper is concerned about heating up the barrel. But it will be very rare indeed, except during some training, when a sniper is going to be firing more than a couple of rounds at a time. We engage key selected targets only. Even in an assault we are taught to keep the rate of fire down as it is not our job to engage MANY targets, we still look for the key targets which will most effect the enemies abiltity to fight. If I shoot 3 riflemen and let the radioman go, I have failed in my mission. If I blast a squad and let their Squad leader go, I also fail. So in situations such as counter ambush, reppeling an assault on a defensive position, etc. the sniper is not going to be to concerned with the problem 95% of the time. Isn’t one of the reasons for the bull barrel better heat management anyway?

Besides, I and many others have dealt just fine with extreme heat (100 plus) and rates of fire of over 1 round a minute for 30 minutes or more with plain bull barrels. Just keep the ammo out of the sun and you will be okay.

When I make comments on here it is to the LE/Military sniper community working in a field environment. You all will notice that I stay away from most of the reloading, bench rest and gunsmithing conversations because many times snipers have to compromise between what is more accurate and that which is more durable/reliable in the field. What may work fine at Perry might cost a grunt his life or at least a failure of a mission. We military and LE snipers should pay attention to what is learned by the National Match, long range and bench rest shooters but we always need to remember that there is not an automatic corrolation between the two.

Keep taking notes.

Fluting – Wouldn’t own it, wouldn’t do it, have no use for it. Gunsmiths love it because it brings in more money! Our M24s fire more rounds rapidly during training than any sniper in his right mind would consider except to prevent a DIP. No change in impact, no change in zero, no problems. We do use sniper rifles and not some fragile rifle that a bench rest shooter, or cross the course shooter would make up. Remember guys, pick one, can’t do both. Either do the sniper rifle or do the accuracy rifle, they are incomaptable. The more accurate the rifle the more fragile it is and the more problems you will have with it in a field environment. I want the weight for aid in steadying the weapon dring firing. I have never seen an equally constructed weapon with fluting beat the accuracy of a non fluted. We tested both and found the fluting to be pretty but not necessary. Fluting done badly is a disaster, ask the guy in Saudi who’s sniper rifle blew at the point where the bottom of the fluting met the bottom of the groove in the rifling. Yes folks it was a custom barrel not factory! The fluting was set too deep by accident. The amount of steel between the two points was not enough to contain the pressure. As Gooch stated, he and I talk about sniping and not bench rest, cross course, reloading, or gunsmithing, just what works after doing this job since 1968.

That flutting has to be done right to be worthwhile of course. I’ve seen it so deep it’s dangerous and so shallow it’s worthless. I was a hard sell myself but I have come over.
Honestly guys there is a real worthwhile reduction in heat there if you don’t consider the few ounces of weight an advantage. You’d have to talk to some real techies on that. I confess! All my rifles are hvy bbls except for a few choice high mountain hunting rifles. I just thought ole Gooch was getting a little off course there and needed to splain hisself to the boy scouts out there. Rick I was 99 percent sure you knew the 300 win was different than the .308 but you come accross with so much info if I prod you a little it’s worth the ass
kickin I get. One more little thing about the weight though. I think there is sure a point of diminishing returns on rifle weight. Some where the piece becomes more unwieldy and harder to repoint (slower) to bear on target. What point is that? Is the strength and training of the shooter the determination of it? Or is there a length factor in the overall weapon. (Leverage affect). Is the application the variance target (which would seem to favor heavier) to “Let’s get the hell out of here Sniper work” or Mountain sheep hunting? Scratch that last one as a factor on this page.

Fluted barrels, it would seem that removing metal from the barrel would allow it to heat up faster. I would think that for a fast two or three shots you would actually get a higher barrel temp from a fluted tube than an uncut tube. Anybody have two identical rifles, one fluted and one not that we could set the pyro on and find out?

Enough on flutting. If it is done by a production line it is hit or miss if it will effect groups. Why take the chance on a Sniper Rifle.

The flutted barrel has more surface area than the round one and also is thinner. Actually the heat is disappated a bit better. Like the coolings fins on your stereo amplifier. Large blocks of metal tend to hold the heat. However certain materials such as silver or copper do conduct heat at a high rate. Aluminum is good but the steel is not really good at it. The nature is from hot to cold. Were there no barrel at all. The heat would immeadiately disappear. Actually as I see it the barrel is a barrier to the heat escaping. The Heavy barrel is stiffer and seems to use the laws of inertia (body at rest tends to stay at rest)when it’s stablized by the shooter. However I should mention that when it’s in motion the same forces (body in motion tends to stay in motion)making it a little slower to bear on target but a little sooner to stabilize at was pointed out. There could be a case for either as a sniper rifle. The shorter heavier barrels seems
to be better for quick work due to the fact that the leverage against the shooter is less than longer barrels so that it tends to stabilize quicker after the shooter attempts to bring it to rest. If one were to measure the outside temperature of a barrel the flutted would probably show a higher temperature sooner. But it would probably cool quicker and it could be argued that that is useless in Sniper applications and I tend to agree. Expansion rate would be a
better check. But who is to say that a rifle might not shoot better if the bore expands a bit as far as the all important group size is concerned (depending on the application). It is just less predictable if it changes. If weight were the criteria for good shooting I would tie a brick on the end of my barrel. But no thanks.

By the way you don’t need to flute to get the same effects and cheaper. Take your barrell to the local body shop. After plugging both end have them sand blast it with heavy grit. The roughing increases the surface area such that infra red emissions are dramatically increased.

As an example fluting increases surface are by maybe 15%, this makes it lighter but for single shot it is only a detriment, for multiple shot a heavy barrell transmits the heat poorly but will absorb sveral shots before deteriorating the performance. But if you are talking a long day at the shooting gallery. Stay in the shade and increase your barrell surface aree by as much as 50% by bead blasting.

I can hear in the background: do both, don’t get sand in the barrell, don’t get sand in the action, how do I know enough is enough, Sarge can be found by the sand trail. All of this whispering in the New
Mexico winds.

Bill – Man I thank you for not reaming me a new one after that post. It came out very blunt and harsh. That was not the intent. I think I took out a bad day on you and that was uncalled for. I think it would be fun and worth while to have a few cold ones and compare notes. You have knowledge in areas that I’m sorely lacking and I’d lke to pick you brain housing. On the weight of a sniper rifle, we prefer heavy due to the positions we have to shoot out of and the heavier weapon helps. The weight is based on the point of diminishing returns. Anything over 14 – 15 pounds gets my nod for dancing on the border. Yes that is the M24! I have walked with it in my arms during Just Cause in Panama, it is not a comfortable weapon and swinging the weapon onto target from the carry position is just plain slow. However, once in a position, and supported, the swing is easy and rapid. Added to this is the fact that with the weight, the weapon “settles” onto target very nicely without the normal “jiggle” that many weapons have after a rapid swing. One of the points for aiding in the swing is where you position your weapon on the support you are using. If a swing to target is expected then position the support more to the trigger guard ( about 1/2 way), if steady is needed, then position the support more to the end of the forestock. This means it takes more movement of the butt to effect the muzzle. While when the support is positioned towards the trigger guard the butt only has to swing alittle to effect a change in the direction of the muzzle. One of the problems in the military is that all weapons must be all things. Thus the M24 is the length required to permit it to be jumped in while fully assembled. I do not know what would be the best length, because, believe it or not, it was never considered in the equation due to the jumping requirement. On strength and training, I feel that the training has more to bear than the strength aspect. The human body is great at becoming strong enough to do what is necessary for the task and the training will make the body strong enough, and teach the body to economize movement.

Again Bill I apoligize for the shortness in that post and thank you for not flaming my butt. Going to bed and dream of a free several weeks without students. They graduated today and I’m off for a whole three days!
