Some time ago I read a piece on fluting of barrels. The gist of it was that a for any given size an unfluted barrel is more repeatable in a string of shots (read barrel heating) then a fluted barrel. (An unfluted barrel is stiffer than a fluted barrel of the same weight) So a 20mm barrel unfluted is better then a 20mm fluted barrel. A same weight unfluted barrel is worse in stiffness than a same weight fluted barrel. Edited by 8shots - March/17/2016 at 03:02 |

Of the same diameter yes, but not of the same weight. (at least the weight before you flute it) One of the main purposes of fluting is because you can use a larger diameter barrel and because of the flutes it weighs the same as a smaller diameter barrel. So to start with it will be heavier and larger, then after you flute it it will be the same weight as the lighter barrel. So the fluted barrel will be stiffer because it is a larger diameter. Your fluted could be a 25mm barrel and weigh the same as a 20mm barrel and it will be stiffer because it is 25mm. Then you get the added benefits of more surface area for cooling. Length plays a huge role in stiffness as well. The shorter the barrel is, the stiffer it is. But obviously at the cost of velocity. Lilja did a good write up of barrel stiffness on their website. http://riflebarrels.com/a-look-at-the-rigidity-of-benchrest-barrels I had a Lilja .308 barrel. It was the heaviest barrel they make and it was fluted and 25" long. That thing was insane accurate. I could literally make 5 shot one hole groups over and over and over again with it. Multiple times at 700 yards I shot a sub 2" five shot groups with it. It was amazing. But it was way to heavy. So I traded for a much shorter lighter barrel.

build is better because you get to build something you kike and to you spec, whether you are right or left handed, but its more expensive
