Yes

There are thousands of them, all bullets are different and BC varies with velocity.

Please be more specific as to which bullets you are interested in.

We need to know, Manufacturer, Calibre, Weight

The most detailed information I have is from the Sierra manual and relates to Sierra bullets, however I assume all other manufacturers are the same, I guess they just choose not to mention it, or average it out.

For example

.243 dia. (6mm) 107 gr. HPBT MatchKing
Stock# 1570

Ballistic Coefficients to Velocity Bounds.
1. 0.527 at 2500 fps. and above.
2. 0.522 from 1800 to 2500 fps.
3. 0.509 from 1600 to 1800 fps.
4. 0.495 at 1600 fps. and below.
