    For each caliber load data listed I see under each bullet..

    BC and a length in thousands and SD and a length in thousands.

    What measurement are they giving me and how do I use it in my reloading. I know what OAL stands for but not BC & SD.

    Pulling my hair out.....LOL

    BC & SD are ballistics numbers, completely unrelated to reloading safety. Read the book, it tells you what the numbes mean.
