    Does anyone know what the twist of the barrel and what is the heaviest bullet the sako 75 will stabilize.
    Thanks

    Hi i think they have a 10 twist if they do it will stabalise any projectile up to 220gr it may stabalise the 240gr Sierra but that would be a gamble.

    I didn't know that Siera made a 220 or a 240gr 7mm bullet. /ubbthreads/images/graemlins/confused.gif

    In the 7mm calibers generaly they all come from the factory with a 1-9 or 1-9.5 twist or at least all the ones I've ever seen from about 5 differant makers.
    should be good up to the 168gr class match bullets.

    Sorry i stuffed up. I was thinking 30 cal. In 7mm they should stabalise the 175gr 7mm MatchKings fine in the larget 7mm's the 10 twist will work so if they have a faster twist than that they are good to go. I think they have a 9.5 twist.

    Cheers Bill
