Really? It all has to do with stiffness, in a particular direction, for a given amount of mass. It might be apples and oranges but fluting is a very efficient way to increase stiffness thus minimizing the amplitude of harmonic vibrations for a given length and weight of barrel. I-beams are very efficient at taking loads considering weight and span. Another approach would be using a lighter, stronger material, such as titanium. But this would likely be even more expensive than fluting.

The key there is equal weight and length. So take a heavy contour and flute it, reducing weight, versus a non-fluted, thinner contour, that weighs the same, the fluted barrel is stiffer. It has larger dementions in 360°.

You said it very well. I think the reason they are becoming more popular is that quality is up and costs are down relative to decades ago because of CNC machinery.

If fluting was detrimental to a barrel I seriously doubt top barrel makers like Bartlein, Krieger, etc would even offer the option. I wouldnt consider Shilen in the same class as these guys.

Agreed.

Agreed again.

A couple months ago I was talking with Lester Bruno (Bruno Shooter Supply, benchrest hall of fame) about accuracy. Asked about fluting he said..... If the barrel was properly stress relived and the barrel is not allowed to get hot while cutting flutes (or cutting octagon) it does not effect accuracy.
I shop at his store, he is a Great resource of info, not that the Internet isn't a good source.

Don't know all there is to know about the topic but I bought a Savage Model 12 BVSS (223 cal.) with a Laminate Wood Stock, AccuTrigger, and Satin Stainless Finish, Fluted just because it looked cool. Oh, and it will almost cover the holes at 100 Yards.

I have the same model in 22-250 1/9 will do that.

Ed shilen told me years ago that it's not that they think fluting is bad for a barrel IF DONE PROPERLY. The reason they do not warranty barrels is they have no control over whether the gunsmith does it right or not.
