Is so, then what type would be the less harmful: linear flutes, dimples, or spiral fluting?
And how come I never see radial fluting (rings of material removed)? |

No. they are designed to remove weight and aid in cooling. some even strengthen the barrel a bit i've been told. Did whoever told you that also explain how they strengthen a barrel by removing material from it? nope...they were trying to explain how putting grooves in a round piece of steel will actually make it stiffer. it made sense sort of, but who the hell knows. he was comparing it to a round aluminum tube and if you put beads down it's length it increases it's rigidity which is true, so i can assume the same would be true for steel. |

Quoted: A fluted barrel of the same length and weight will be stiffer than an unfluted barrel of the same weight and length. Fluting a barrel will not make it stiffer though. For example if you have 2 identical barrels and you flute one it will be less stiff than the unfluted one.

Here's a Link to one of the best articles I've ever seen on making barrels and accuracy. If you read the section on profiling contours, the author makes a case that any profiling of BUTTON rifled barrels after rifling CAN affect acccuracy. Probably not enough for ME to notice, but possible. AN intresting read, at any rate.

Same concept as to why I-beams are the shape they are, or the reason connecting rods are profiled the way they are. Cuts weight and maintains strength. |

Two identical barrels, flute one, it wont be as stiff as the unfluted one. It will however weigh less. If you take a HBAR and flute it to weigh the same as a midweight, it will be stiffer than the midweight. Get it? |

The real question is a barrel stronger or weaker before or after it has been fluted? |

I shot a long range stage last year with one of my bolt action guns. There was a stage that was essentially 30 rounds as fast as you could work the bolt shooting at 1" dots at 100 yards. As hot as my barrel got (and trust me, it was searing hot) it had no trouble putting rounds into the 1" dots. A quality barrel should have very little POI shift due to heat. |

Good article just on fluting.
