It is basically how easily a bullet goes through the air. or said a different way, how well it keeps its velocity. A higher BC means teh bullet won't lose as much velocity over its travels as one with a lower BC. It is a ratio - so it is from .000 (think pushing a cup into the wind) to 1.000 (super slick missile).

If you don't know what it is, knowing it for that round is probably is not going to do you any good.

The Federal website shows basics ballistics for both American eagle .308 rounds:

150gr fmj

168gr otm:

You could probably email them and ask, or ball park calculate from their info there.

If it is that vital, you would probably be better off buying different ammo, and/or working up exactly what teh drop is in your rifle.
