if you recall high school physics it is best to think of B.C. as the coefficient of friction (drag in the case of aerodynamics)...
probably the closest visual cue to B.C that I have found is the length/girth ratio.
so the larger the girth of the round the more "draggy" light projectiles will get when the projectile gets shorter...
