How to use ballistic coefficient (SI units)?

  1. Jun 11, 2013 #1
    Reading in Russian sources I see they use ballistic coefficients such as these:

    BC = 3.0 kg/m^2

    or alternatively

    BC = 3.0 m^2/kg

    That's quite different than the usual G1, G7, etc.

    Given a certain muzzle velocity, how do I use that to calculate velocity at some point downrange?
