[QUOTE="BryanLitz, post: 493376, member: 7848"] It's not really important. The importance of a 'standard projectile' is it's profile (shape). It doesn't matter what caliber, or weight it is. The standard projectile has a 'standard drag curve' that we reference with other bullets. The sectional density of the bullet is used to account for the caliber and mass of the bullet. You could say the standard caliber and mass of the standard projectile is 1 inch and 1 pound, giving it a sectional density of 1.000, but the real answer is that it doesn't matter in the context of how the ballistic equations of motion are solved. -Bryan [/QUOTE]
