    I'm trying to put together some drop charts for some new ammo I'm trying. I bought some Federal Power-Shok .308 180gr soft points. They don't list the ballistic coefficient on their website. Where can I look to find this info?

    JBM - Calculations

    JBM has calculators to figure BC. Using Federals velocity numbers I get a BC of .389. This looks close compared to there wind drift figures also.
