LOL....
Let’s go pure simpleton on this:
two bullets of the same weight/caliber will have the exact same SD, regardless of shape, simply because of the simpleton math behind SD. The one with the most aerodynamic shape at the same weight/caliber will have a much higher BC AND the same SD.....therefore, worshipping SD is going full retard, when a mere change in bullet shape can kick its ass by it’s own math.
Not to mention bullet construction, which affects penetration.
