Anyways, the barrel does not cool that much faster that it would be worth doing for that reason. Accuracy has never been an issue for me, as I order my barrels flutted from the barrel manufacturer.
They have the proper equipment to ensure a stress free barrel after they flute it. Hope this helps a little. I know there will be different opinions on this subject. I personally like flutting for the looks alone, so I would do it. Colonel Full Member. Jan 9, 7, 13 Southern Indiana www. Removing metal does not make a barrel more rigid. Removing metal will allow a barrel to cool faster Most fluting is for cosmetic purposes.
Sometimes it's to get under a weight limit in competition. The basic rule is if you don't need it, don't get it. You just spend more to get less. Dec 10, 4, 13 41 Michigan. There is no actual evidence o suggest that fluted barrels: 1. Are any more or less accurate than non fluted 2. Cool significantly faster 3. Do anything for you other than save a little weight and provide an aesthetic difference.
I like fluted barrels, so I get them. When possible, get your fluted barrel from the barrel maker that way. Like many things in the world of shooting I think there are some advantages behind the engineering aspects of fluted barrels and they have some merit.
At the end of the day, it's whatever works for you and makes you happy Diablo Road Warrior Supporter. Full Member. Aug 29, Agree with what LoneWolf said. As for those of you that think fluting adversely affects accuracy, how UN-accurate do you think the barrels are with "decorative" twist-fluting and intermittent fluting?
And yes, cutting flutes does result in more surface area in contact with air, thus it likely will cool faster even if you haven't figured out a way to measure the difference. Who really cares? Get whatever you like. The important thing is to get out and shoot it. Feb 6, 1, Wolftown. I like it but that is just me. That would be hard not to like, looks good! I'm a firm believer fluting makes the barrel more rigid, but don't want to get into any arguments over it. From my standpoint, if I'm going to hammer a gun, and shoot the barrel out in a one year period, fluting is just a waste of money.
I had my last barrel fluted, with vulcanized rubber imbedded in it, shot it out in 7mos. If it is a hunting gun, or one I will not abuse, I would flute it.

Also another thought, does the spiral flute reduce more, less, or the same weight as strait flutes? Gregch44 Private Full Member. Nov 23, 49 0 62 Upstate NY. I don't think that it makes a real world difference.
Weight reduction would be the most real followed by astetics. I personally don't care for the fluted look. That is just me, to each their own.
Barrel fluting is very popular for sure. Sep 15, 0 44 Southern California LA. I've always liked the look of those spiral fluted barrels. Not sure if it helps with cooling, accuracy, etc, but it sure looks cool. ChielScape Private Minuteman. The new equipment available to shops today is capable of fluting much faster than what is good from the barrel.
So there you have it. Two data points - one totally theoretical and one very much practical, that indicate that a fluted barrel can be beneficial to accuracy - when done properly and under the right conditions.
Shooters looking for a lighter weight rifle often resort to fluting the barrel. I've heard some tell me emphatically that fluting a barrel makes it stiffer, and therefore helps accuracy.
Others say that a fluted barrel is not, in fact, stiffer and that accuracy may even be hurt. Lets start out by stating that there are two kinds of stiffness. Static stiffness and dynamic stiffness. Static stiffness is defined by the deformation the barrel would undergo if you locked the action rigidly in a vise and hung a weight on the muzzle. The barrel will bend downwards slightly.
A stiffer barrel will bend less than a more compliant barrel. The static stiffness depends on the geometry and material of the barrel.
Simple enough. What I'll call "dynamic stiffness" is a little more complex. Just as static stiffness determines how far a barrel will bend if you push on it, dynamic stiffness determines how a barrel will move while under a dynamic load such as firing a round.
Dynamic stiffness is impacted by many things - the static stiffness of the barrel more generally, the barrel's geometry , the mass of the barrel, the way it is attached to the rifle, the type of round fired, and many other factors.
A note to the engineers out there - I'm being intentionally vague here in the name of clarity. So what is the effect of stiffness on accuracy? I don't know. It's not a simple question to answer. I cannot think of a rational argument for why static stiffness matters at all, except that it has an impact on dynamic stiffness.
Dynamic stiffness most certainly does matter. When a rifle is fired, the barrel vibrates in a whipping motion almost always an up-to-down dominated motion as the bullet travels down the bore. Where, exactly, the muzzle happens to be when it the bullet leaves the barrel will impact accuracy.
That's why handloaders "tune" their load to their rifles. They are looking for a load that consistently leaves the barrel at the same point in its vibration cycle. Now we come to the one advantage claimed for fluting that is generally taken for granted, and that is that fluting makes a barrel stiffer.
I always assumed that contention was true, but is it really? It is therefore difficult to imagine it flexing to any extent, but it definitely does as a bullet accelerates down the bore.
Imagine a garden hose stretched in a straight line along the ground. If you pick up one end of it and shake it violently up and down, a wave action is created that travels down the length of the hose.
A gun barrel does much the same when a bullet is sent through it. It seems logical then that the stiffer the barrel, the more accurate it can be. One need only look at benchrest records comparing Light Varmint pound and Heavy Varmint Most of the miniscule difference in accuracy is due to the fact you can hold a heavier gun steadier.
Another common sense notion about stiffness comes from everyday experience. An ordinary sheet of paper goes limp when you pick it up at one end.
Another good example is a steel tape measure. If it were flat, it would not extend far. So chalk up another seemingly intuitive thing that tells us a fluted barrel must be stiffer than a smooth barrel.
Fact of the matter is, fluting does not stiffen a barrel as logic would seem to dictate, not according to the several structural engineers and metallurgists who wrote me after I had said so in print.
The gist of what they all said was that whenever you remove material from an object, you weaken it. This can be demonstrated quite graphically by a procedure my friend and colleague John Dustin came up with to satisfy his own curiosity.
John is a well-known accuracy gunsmith and competitive benchrest shooter as well as a writer, and he devised a simple demonstration using a lathe chuck, a weight and a dial indicator. He took a chambered, unfluted 6. He also noted the amount of torque applied when locking the jaws of the chuck so there would be no disparity there. At the unsupported muzzle end of the barrel, a dial indicator was placed and set at an arbitrary value. The results?
