[QUOTE="Brown Dog, post: 120852, member: 1622"] …..I'm still keen to learn how the faster bullet is ignoring Newton’s First Law of Motion by somehow ‘remembering’ the force that caused its initial deceleration for the rest of its flight? [img]/ubbthreads/images/graemlins/confused.gif[/img] …. I believe, as others have pointed out, the only explanation for the higher mv bullet being ‘beaten’ at long range must be (since both bullets will have identical zero yaw drag when at the same velocities) that the faster bullet (in the case of the '50yds less' example) must have had greater yaw drag for its entire flight (ie it hasn’t been properly stabilised). ...presumably the doppler data quoted only treated the projectile as a point mass ....and gave no direct yaw data?
