[QUOTE="chuckhammer, post: 1087468, member: 25816"] Sure thing. The BC formula also includes the equally important "Coefficient of Form," or "Form Factor" as it is commonly referred: BC = M / (D^2 * FF) where: M = bullet mass (grains/7000) D = bullet diameter (inches) FF = Form Factor (per the corresponding G-model) Stated differently, it's Sectional Density divided by Form Factor. That means caliber and mass matter just as much as "sleekness," generically speaking. [/QUOTE]
