I am simply arguing that fluting can make a rifle more accurate by keeping it cooler in some applications....
There is absolutely NO science to support this.
Physics and common sense are against your argument in every way. Fluting is fad that some think makes a rifle "look cool" but that does NOT make it in reality. No matter how you cut it, the detriments of fluting a barrel grossly outweigh any positive points. The "reputable" gun makers will do ANYTHING to try and sell a gun. The next thing we will see is triangular barrels being touted as the superior barrel to use. Oh wait 1 reputable gunmaker already does this.
Facts are.
Fluting is NEVER uniform, the depths vary from flute to flute and even in the same flute over the length of the barrel. Steel by nature tends to deflect and become mildly banana shaped when milled longitudinally.
Differing thickness of material in the same plane will cause distortion at a differing degree from heat/cold. Uneven surfaces heat and cool unevenly. Uniformity equals accuracy, the basic theory of harmonics.
Firecracking occurs more prevalently on the thinner areas than the thicker areas, this can readily be seen with a borescope, you can actually see the flutes from the inside of a fluted barrel as the firecracking is considerably worse where material has been cut.
Fluted barrels are seldom truly straight due to the warpage of the barrel during the machine work to make the flutes. Seldom is the stress relieveing sufficient to release all the stress's induced by the machining.
Seldom does a properly turned barrel blank need to be straightened, yet most fluted barrels REQUIRE starightening after fluting is done.
We took an old heavy barrel and fluted it whilst collecting all of the chips, the weight saving was a whopping 5 ounces. If that is so terribly significant a weight reduction, 1 needs to seriously contemplate some quality time on the stairmaster. There are better ways to save weight.
If 1 needs to worry about their barrel heating up so much because they need to take so many shots at something, maybe some shooting lessons and practice would be an idea. I have never figured out why 1 needs to take many shots a coyote, I have shot hundreds of them and seldom required more than 1 shot to make 1 play dead.
Please do not take offense as none is intended, just trying to help you see the facts.
