More Inaccurate Specifications of Ballistic Coefficients

Abstract

A ballistic coefficient (BC) can be determined by using two chronographs a measured distance away from each other and shooting a bullet so the velocity is measured by the two devices. Ballistic modeling software requires accurate measurement of ballistic coefficients to accurately predict downrange trajectories, wind drift, and retained energy. This article presents new measurements for 21 different bullets and shows that BCs can differ significantly from the claims of the manufacturer. These differences can cause significant differences in the predictions of ballistic modeling software. Evidence suggests that these variations are probably not due to excessive bullet yaw.
