Unless you want the actual coefficient, then you would need to know your muzzle velocity. Zero you gun at 100 yards, shoot at various distances (200, 300 yards) measure bullet drop for each distance. Then using a ballistic calculator play with the BC until your bullet drops match what the calculator puts out.
