After watching the video the question in my mind is "what causes the drag variability in the sharp pointed bullets?" The presenters don't address the why, but rather suggest the reason is that the tips are pointed. My thought is that manufacturing tolerances become increasingly difficult to maintain as the taper increases. Individual bullets with perfect axial symmetry have less drag than those with slightly off center tips because a bullet tip that is not perfectly centered on the axis of rotation actually circles around the axis when in flight.
Hornady perhaps has found a properly sized meplat that trades a bit of drag reduction for consistency and optimized it relative to other bullet shape dimensions. If my supposition is true, future improvements in bullet mfg may negate the design improvement Hornady has developed. By developing the improvement and patenting it, Hornady may drive others to develop improved mfg techniques.
In any case, this is another example of Hornady's continuous efforts to provide better products for the consumer.
