    Form Factor vs BC vs Drag Coefficient

    I need some help understanding why the formula to calculate the BC of a projectile is what it is. In Bryan Litz’s AB for LR Shooting (3rd Ed), he writes: BC = (projectile weight) / (cal^2 * i) Where “i” is the form factor of the projectile’s drag coefficient as it compares to the standard G1...
