I believe the BC is in the area of around .390 for M80 ball, and if I remember correctly, my 18" FAL got it going to around 2750fps.
As for determining BC, the JBM website has great tools for that. You can pull a few and measure them. Put the data through the calculator on the website, and out comes a nice BC table.
