If two bullets are of the same caliber and weight the one with the higher BC will have less drop, wind drift, and more retained energy. this becomes more recognizable the farther the bullet travels from the muzzle. It is a funky calculation of bullet length, mass, cross sectional area, density, and drag coefficient. = ballistic coefficient
All of this does not make a hill of beans difference for big game hunting bullets when shots are out to 300 yards or less.
Makes a huge difference for the Long Range guys that shoot out to 1000 yards.
