    I have an 8 twist that shoots everything up to 82s just fine.

    What velocity are you getting with the 82's?

    Let me know what you think after you shoot it

    I'm wondering if it would work on th 90's. It would be an alternative to a 224 Valkrie.

    Will do, I have brass ready to shoot in th 22BR and just need to finish load testing on a .222Rem that has been in the safe way too long.

    Pro; Can stabilize heavier bullets with higher BC's, less drop, less affected by the wind.

    Con; For any given bullet you cannot achieve as high a velocity as you can with a slower twist barrel, more drop and more wind effect.

    Yes, I have had a 7" twist 22BR and a BRX (and still have a 9" twist 22BR).
    The 7" twist with 90gn Sierras and Bergers was great to shoot and very accurate. My best shoot was 2 targets at 600Y which scored the equivalent of 200/19X on your F class targets. The ballistics with the 90s was slightly better than a 6BR, with lighter recoil. Down side was lower barrel life compared to 6BR, and when I utilized the extra velocity of the BRX, some Sierras started coming apart once the barrel started to get a rough throat.

    I’ve had good luck with 90’s and 1-7 twists on my 22br , just rebarreled it! I have to make sure that the throat is long enough for base to be in the case neck or it doesn’t work well.
