    Which Twist Rate

    im in the market to replace my barrel. i have no idea what twist rate my barrel is. i shoot whatever i can get. 55 gr to 69 nato. i dont shoot matches with this gun and dont hunt. just defense and target practice. what would be the best twist reate for me. middle of the road 1in8? is there a certain bullet weight for a certain twist.
    55 to 69 for a 1 in 9 etc

    1/7 is the only twist anyone needs. everybody has their own theories/thinking on these things, but the fact remains. 1/7s will stabilize 45gr HPs, all the way up to 80gr SMK.

    I've got both and the 1/8's are a J&T bull barrel and one is a Lilja. They are literal tack drivers with lots of the "surplus" ammo I have fired through them. Haven't fired the Lilja barrel much as I just recieved it several days ago but the J&T barrel will shoot well under an inch.
    What ever one you get a good deal on should be sufficient for your stated use.

    1/8 and 1/7 are the two best options. I would stay away from 1/9 twist rate.

    FACT. I've owned 1/7, 1/8, and 1/9. The 1/9s were subpar for various reasons. 1/8 was fine, but I stopped using the rifle for a long time and got rid of it. 1/7 will shoot anything you feed it, usually more accurately than you.

    Anyone who tells you that 1/9 is fine, is just trying to justify to their self, that it was ok to purchase a subpar piece of kit.

    If there were any real merit to the 1/9 twist rate, more high end makers would be using it.

    We are talking about a 16" barrel, right?

    1:7'' would be ideal.

    However, a 20'' HBAR with a 1:9'' twist, is pretty damn accurate with 55 gr. rounds.



    BTW: Who makes 80 gr. SMK? Does the extra 3 gr. make a difference?

    i use 1/9 and 1/7 for 99% of what i do. if you are going to replace a barrel then i would go with 1/7 as it give you the option of useing a wider range of ammo say 55gr- 77gr. if you choose to.
