    Call Remington first thing Monday morning and they can tell you what it is for sure. They don't mind, that's why they have a customer service dept. Gotta make those guys and gals feel useful you know.

    Folks younger than my generation are so used to being able to find the answers to just about any question on google they just don't think the same way we do about such things LOL

    Old school may be slower but it works! gun)gun)gun)

    Why don't you measure it yourself?

    edd............ amen

    step 1
    mark cleaning rod for length and make an indexing mark at least 14" outside fo barrel.

    step 2
    push rod in until the index mark is back at the same place
    mark rod

    step 3 measure the distance between marks

    I would measure it myself but the rifle is still riding in the big brown truck on its way to me. Im trying to round up components before hand

    If you don't have it to measure, I'll guess. My guess is 9.25".

    Most all new 700's in 7mm calibers are 9.25" twist.

    You will be fine with the Berger 168's.

    He is wanting to shoot Barnes 168gr bullets. They are longer than Berger 168gr bullets.

    If you use the Berger twist calculator, the Barnes bullets have marginal stability below 5000 ft with a 9" twist.

    I'm below 5000 feet and both of my Remingtons with 9.25" twists shoot 168 Bergers just fine, and one of them shoots Berger 180's fine.

    The 168gr BARNES is longer than the 180 gr Berger.
