    reduced heat capacity

      Wrong, the heat capacity is the exactly same for a given barrel weight and the cooling capability is slightly better.

      Nothing really. It's just cost. Same reason why barrels are often constant diameter.

          Are you? The goal of barrel fluting is to inherently improve the mechanical properties of the barrel.
          For a given weight the barrel will be more rigid.
          For a given rigidity the barrel will be lighter.
          It does not inherently reduce heat capacity.

              anon he is moronic, let him be.

              The problem is nobody seems to take these very seriously because military units don't use them. The only reason the government doesn't use them is because it's not economically feasible on mass scale. Just think about how the civilian market STILL just cannot stop buying the government profile barrel. Or how said AR crowd is only very recently "understanding" what ammo is actually accurate out of a 1:7 twist barrel(it'snot the bullet weight). You've got to realize that half of all people are below average and don't think for themselves as much as they think they do.

                That's not true at all. The government can afford what it chooses to when it comes to small arms. The military didn't adopt fluted barrels because it's just not that much of an improvement.

                Then what determines accuracy?

                It's a function of BC. The longer and thinner a bullet is, the faster it needs to spin. Weight doesn't tell the whole story. Solid copper projectiles the same weight as lead core need a faster minimum twist rate. That being said, I've seen .224 Valkyrie stabilize 77gr SCHP with a 1:7 which is way thinner than anything 5.56 will fit. Not sure what you could put in a 5.56 that 1:7 wouldn't stabilize.

                You know just enough to know nothing. Everything is part of accuracy, the dampening of barrel harmonics, the consistency of the ammunition and it having been tuned with the harmonics, avoiding crossing the trans sonic barrier, locktime, the quality and precision of the sights, the shooter and their consistency, the crown of the rifle, the finish on the rifling, the manner in which the rifle is loaded, the quality of the chamber and throat and bolt face, the quality of the trigger and much more.

                You don't seem to be paying much attention to the thread. You're talking about accuracy in general, meanwhile anon's comment was about barrel twist rates specifically.

                Ideal twist rate is a function of bullet length, BC and bullet weight are correlated to bullet length.

                But the military does use flutes on occasion, like with the SDMR barrels.

              Fluting refers to the shape of the barrel. Not its weight.

                He's right fluting is typically a weight reduction that gives the same stiffness as bull barrels the problem with both is that the vibration such as there is is harder to eliminate, which can be accomplished on lighter barrels.

            Meanwhile, in reality, manufacturers just flute the same barrel stock for a given model 95% of the time.

          Nobody takes a barrel and just flutes it, that's not how it works.
          Fluting is an element incorporated into the design at the design stage. The shape and size of the fluting is decided upon at the same time as the diameter/weight and diameter/weight distribution is decided upon.

          Your weight will probably be dictated by your heat capacity requirement in semi auto rifles and therefore fluting has absolutely no effect on weight.

      Increased surface area means it radiates heat more efficiently though, and thus cools faster.

      • 4 weeks ago
        Anonymous

        I don't think most fluted barrels are going to have significantly greater surface area (certainly not for radiation which isn't particularly relevant anyway compared to convection), the surface area of the convex normal barrel just gets inverted into the concave parts of the fluted barrel.
        They mostly cool down faster because when the manufacturer milled out all that material the total heat capacity of the barrel was reduced, while the convective and radiative properties remained similar.

    You can cause accuracy problems during the process of cutting the flutes if not done carefully.

    They both heat up and cool down faster. It’s a fantastic compromise and worth the money in my book for the weight savings.

    what vibrations do occur are harden to damped using for example a barrel tuner. I prefer a lighter barrel and then use the silencer as a barrel tuner. It takes some work but will give superior results. Also have a look at the barrel dampers

    has there been any research into what fluting pattern is the best, or any comparison between fluting patterns. By best I mean provides the lightest weight for a given rigidity. however, there may be other considerations like heat dissipation, so also interested in that.

    for example, im fairly certain spiral fluting is not as rigid as straight fluting, though heat dissipation may be better than straight fluting. I also think the most common "diamond" fluting I see, where there the diamond pattern is raised, is also not good for rigidity. But the inverse, where the diamond pattern is the low, milled out part, that would actually be fairly high in rigidity.

    and then things like hexagonal/octagonal barrels may also compare favorably to fluting.
