[QUOTE="Michael Courtney, post: 864484, member: 28191"] The data might be analyzed to determine typical tip off angles and damping rates for a given bullet in a given rifle, but the damping rate would only apply to a given bullet, and the tip off rate would only apply to a given rifle. A hobby level enthusiast would then need a 6 degree of freedom numerical model (like the one described by Robert McCoy and used by Bryan Litz) to apply the information. The bigger practical effect for most hobbyists is how much BC variation there is between different rifles. Knowing the BC for a given bullet in a given rifle is probably the best improvement a hobbyist can make and much more important for predicting long range trajectories than such minutae as tip off angles and damping rates.
