.308 twist rate

I want a 16inch barrel .308 but with a 1:5 twist. What are the advantages to this as opposed to the average 1:10 twist?

    reduced bullet selection, that's about it.

      Why?

        NTA but too fast of a twist and full power velocity can shred bullets. That’s why 1:3 for 8.6 blacked is a meme

              I have never once seen any .308 vaporize itself in the air from a high twist rate. I have for .223, but not .308, it weighs 3 times as much as .223. So that's like, it would need to go 3 times faster to vaporize itself, and that's around 8400fps just to vaporize itself.

                You've never seen a .308 with a fast twist rate.

                get into pi and angular velocity

                my Black person in Christ, have you bothered to ponder what happens to rotational forces as the object gets larger on the axis of rotation and if the relationship between rotational velocity and centripetal force is linear or exponential?

                556 doesn't vaporize despite reaching an rpm of over 339,000 out of a 1:7 3300fps 20 inch barrel.
                What makes you think a 150gr .308 at 2600fps and a rpm of 374,000 from a 1:5 twist 16 inch barrel will immediately vaporize itself?

    I've used an artifical intelligence answer me the question as to why a higher twist rate on an ar10 would be better, the short answer is that it would increase stabilization at longer ranges and increase the destructive force of the bullet due to an increase in rotational energy that is imparted at the point of impact?

    But I still don't understand why it's bad for .308 rifles. Wouldn't you want an increase in long range stability and energy imparted to make it better at killing?

      this is why you don't ask AI technical questions, it just regurgitated a bunch of bullshit to you and you believed it.
      > increase stabilization at longer ranges
      no, once you sufficiently stabilize a bullet it stays stabilized for the duration of the flight, any more stabilization just causes added spin drift (pushes your shots off target) and if you go too high the bullet will just disintegrate from centrifugal forces
      > increase in rotational energy that is imparted at the point of impact
      this is technically true but in reality the difference that the rotational energy makes is nothing. you may see certain companies try to say that it does matter, but that's just because they're trying to push their stupid meme round onto gullible idiots like you.

      But the AI...says it's not a bad thing?

      then go ahead and blindly believe the stupid fancy autocomplete that regurgitates bullshit fuddlore it pulled off the internet, no skin off my balls

      you used a language model, that just regurgitates stuff that is convincingly language. that's why it says moronic make-believe bullshit, like what you posted.

    What bullet weights do you plan on using

        Then you want a 1:14. Getting a 1:5 would be moronic

    Too fast of a twist can actually lead to jacket seperation. I've never personally seen anything faster than 1:8, and those are for dedicated subsonic builds. Just blindly increasing twist doesn't magically make a bullet somehow more stable over a longer range. Why the frick you're even worrying about long range stability with a 16" .308 is beyond me. Wind and drop are gonna effect your projo way more than how fast it's spinning.

        It's just a language model, it regurgitates whatever shit seems most relevant to your prompts. It's not intelligent in the least. You're better off lurking Sniper's Hide, Accurate Shooter, 6mmBR, etc. I'd even trust r/longrange over your imaginary computer friend.

        We really need to get away from that word. The only things these programs "know" is contextualizing language. All its doing is scouring the internet to spit back a string of words to fit your question.

          Not even that, it just does a shitload of statistics to put words where they would most likely be if [their training data set] were speaking

        LLMs are not capable of understanding ideas and concepts, then making inferences based on how those concepts interact with other concepts. They use statistics to more or less guess (and often, hallucinate something totally wrong) a "right-sounding" answer. They can't think or analyze, and apparently neither can you

    Twist rates are broadly proportional to the caliber of the round, that's why a .223 has a 1:7 twist while an 18" naval gun has a 1:507 twist. As others have said, a 1:5 for .308 is silly.

    If you all say so then I'll believe you, so I'll just go with the standard 1:7 twist that the US Army goes with or 1:8 if that's the fastest i can find a barrel in.

        How? Us army uses 1:8 twist for their .308 rifles, if they use it then I'll use the same twist as them.

          No they don't.
          1:12 was standard for M80 ball. 1:10 is for the longer M118 and Mk316 bullets.

    Frick it, ima still make a 1:5 twist 16 inch barrel! I need that full 3 rotations! And I need that bullet to spin to maximize fragmentation.
