    I need ballistics data including BC for the Black Hills factory match 175 gr. HPBT to 1000 yards. I've found some trajectory info out to 500, but no further. I haven't found a BC either. Complicating the whole thing is that I will shoot with a 30" barrel. I'm not sure if there is a standard length test barrel for generating ballistics but I'll bet it's shorter than 30". Is there any calculation to compensate for the longer barrel? Lots of questions because I'm new at this. Thanks for any help.

    Bro, seeing as your from the Seattle area, shoot me a PM and I will put you in touch with a person that can make your long range shooting dreams come true 10 fold.....

    And it won't be on a 30" .308 caliber 175grain platform....

    175gr Sierra Matchking. Check out JBM ballistics online.

    You should know your specific muzzle velocity, but a close approximation will let you fine tune yourself.
