  • Site for questions on rifle twist

    Every now and then we have topics about what twist is best for particular bullets.
    I was looking at JBM Ballastics and they have a section on bullets and twists, which twist the bullet will be unstable, marginally unstable and stable.
    Might be helpful.

      I find Berger's very useful, the bullet library is helpful too. http://www.bergerbullets.com/twist-rate-calculator/
      Quote from the Rev. Martin Niemöller, a Holocaust survivor:

      First, they came for the Socialists, and I did not speak out -- because I was not a Socialist.

      Then they came for the Trade Unionists, and I did not speak out -- because I was not a Trade Unionist.

      Then they came for the Jews, and I did not speak out -- because I was not a Jew.

      Then they came for me -- and there was no one left to speak for me.

        Pretty good on the cbal. I use the Berger library quite a bit. One more tool.
        Apparently not too many handloaders are not aware of these tools that we can use.

          People just don't think to look DM.

          Over on SGW just 2 days ago a guy was wondering (among .410 plans involving his 8-yr-old) about recoil comparison between typical 1/2 ounce lead 1200fps load and a 3/8-oz 1400fps steel load someone mentioned.

          Heck, why wonder,,,, a dozen Recoil Calculator's are but a google or bing away here on Algore's Internet.
