    Depending on how much you want to pack around, you will gain about 35-40 feet per inch of barrel length. I would personally set a MINIMUM of 26". A longer barrel usually requires a little heavier contour. I would go with a 12 twist( if you are sure that you aren't going to shoot more than 87 grain bullets)!!........Rich

    My 25-06 has a 28 inch tube on it and I like the 87gr. bullets.
