Web2 de fev. de 2011 · A heavier bullet will have a better (higher) sectional density than a lighter bullet of the same caliber. For this reason, bullets that are lighter tend to have a lower ballistic coefficient than heavier bullets (assuming of course that the bullets have the same aerodynamic shape). WebTHE BALLISTIC COEFFICIENT . William T. McDonald . Ted C. Almgren . December, 2008 . The term “ballistic coefficient” is familiar to most shooters today. They know that the ballistic coefficient of a bullet is a measure of how well it retains velocity as it travels downrange and how well it “bucks” the wind. However, few shooters really know
