Why did Berger change their twist rates?

When I had ordered my rifle, Berger's recommended twist for a 130gr 6.5mm VLD was 1 -9". Now it's 1 -8"? How often were the 130's not working in the 1 - 9" to need the increase in the recommended twist?

    I'm not sure why they should /would change the rate of twist for the 130gr bullet
    because the recommended twist for the 6.5 is 120gr=1 in 10, 140gr = 1 in 9 twist,and
    anything over 140gr should need a 1 in 8 twist.

    I don't think you will have any problems with the 1 in 9 twist at all . in fact I think you chose
    the right twist for your barrel. and the 120s,130s,and 140s should do well.

    Just My opinion

    I have an old box of 140 grain Berger 6.5's and they say 1 in 9 twist or faster with a .640 BC. I also have a new box of 140's that say 1 in 8 twist or faster with a .595 BC. So I guess they have changed their suggested barrel twist.

    Berger really missed me up on this.

    I ordered a 1/9 barrel to shoot 6.5 140's and bought 500 bullets to start me out with.

    I still think you will be OK with the 1 in 9 twist especially if your velocity is in the upper
    range of the 6.5.

    Sorry to hear that !!!!!!!!!

    You may have to cut your losses and switch to a conventional bullet .

    Try a 130 gr accubond and I think you will be pleased.

    Just in case there is another problem keep the Berger's until you are happy with another bullet
    and then sell the Berger's.
