    what twist rate would someone want for the 6.5 Grendel? there are 1/8.5 and a 1/9 and some that are not marked. should i simply build the upper with a specific twist or order from Alexander arms? does someone else make an upper in the caliber?:confused: thanks in advance.

    I went to yahoo and searched for
    6.5 grendel twist rate
    and
    ta da
    http://www.alexanderarms.com/faq.htm#WHAT IS THE TWIST RATE ON THE 19.5 Grendel, THE 24 Grendel?

    I am not convinced you'd notice a difference between 1in8.5 and 1in9 with bullets lighter than 140 gr.

    EDIT: come to think of it, that doesn't really answer your question. After reading a little, AA is rather quirky about the twist rate. Kinda sounds like BS to me, but who knows. My guess would be they got a better deal on one particular barrel when building a particular configuration.

    Truthfully

    If you're interested in a particular bullet, call up the manufacturer and ask them. Sierra is really helpful from what I here (as are others)

    Or you could just go with a 1 in 8" barrel and not have to worry about it. In fact, Lapua recommends a 1 in 8" for the 123 gr Scenar.

    I really think AA is BSing on some of that twist rate stuff.

    Get a 1 in 8" and be done with it.

    EDIT: Okay, after reading that again they do mention bullet weights. That's what the twist rate optimized for.
