    I was wondering if anyone knows what a average minimum velocity berger vld bullets need to expand reliably. I know most bullet manufactures say they recommend 1800 to 2200 fps to expand. I know bergers are supposed to work a little differently than most hunting bullets.

    I can help you out.

    I got an e-mail from Walt Berger, where he wrote that for full and complete expansion you should have minimum 1800 fps, so that is what have used allways.

    I asked about 30 cal, but I guess for any cal berger bullet I would not go lower.

    I also got an email from Walt, specifically for the 168, 175 and 185 30 cal bullets.

    Hi Mark,
    Adequate expansion is achieved above 1825 fps.

    Hello Walt,

    I was wondering if you could provide me with the minimum performance velocities of the 30 cal 168, 175 and 185 VLD bullets for expansion on game.

    Thanks,

    Mark

    I got the same info as pretex, from the same source.

    I let a 115 VLD in 6mm impact an antelope at 1880fps and it worked great.

    I think Walt knows what he is talking about and he makes great bullets.
