    Hello,
    This barrel looks realy good. Yes, with a bore of 77mm the Maney barrel does tend to distort, if Nikasil- coated. The Molnar barrel with the all casted in through bolts looks a lot stiffer and so the tendency for distorton seems less. If i had the right financial background I'd like to try one.

    Told you!

    Worth mentioning that some bore sizes have iron liners; the 650 versions, for instance.

    I guess the bigger bores, like 81mm, have steel liners too do they? I’d have thought they’d need the addd strength.
