Not really, think, 22 subs are 0.12 Besides isn't BC relative to MV anyway? (Lower the mv the lower the BC)
BC has nothing at all to do with MV.... it is a function of the 'slipperyness' or inverse of aero drag, relative to a 'standard projectile'...
Then how do you explain this:

(just as a example) scroll down to where it stipulates the BCs based on MV ranges. Not that I'm mathematical enough to really argue, I don't think it's quite as simple as you make it out to be. I might be wrong...
Yes... for a given bullet the BC will vary to a degree.... I was referring to your comment;

lower mv = lower BC is absolutely not the case...as a generalisation...
If referring to specific projectiles and the slight variation over velocity - even your example has an increasing BC with reducing velocity....
