WebIn brief, the ballistic coefficient is a mathematical representation of how streamlined a bullet is, i.e., projectile's ability to resist air drag. As a numeric designation, the ballistic coefficient (BC) is usually described as a number between one and zero. Common FAQ Is a higher ballistic coefficient better than lower? 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).

WebEffectively, the bullet behaves as if it has a higher ballistic coefficient. Forum members Milanuk explain that the key factor is not altitude, but rather air pressure. Milanuk writes: “In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. WebComparing Advertised Ballistic Coefficients with Independent Measurements 5b ... tail bullet designs, especially at long range.
