    Dear all,

    could you perhaps help me with this:

    is it possible to identify the probable barrel twist rate from its serial number?
    I own a 7 mm Wby, which just does not stabilize the bullets.

    The serial number is H 240 8xx. It has been made in Japan. I was told the older barrels have 1:12, whereas the newer have 1:10.

    Thanks a million
