Projectiles of like mass/diameter ALWAYS have IDENTICAL SD(Sectional Density),though BC's vary wildly. Hint.
Thus the fhuqking HILARITY of SD "values",which measures only the schit,that do NOT matter. Hint.
I enjoy the ladies musing 4-500yd "greatness" ala 270,less a mention of the projectile incorporated. 'Course,no mention of the optic either. Hint.
Berger throws mass at the equation,but misses BC by miles. Pardon the 153.5 grainer having a better BC than the 156...though the Hornie 153 A-Tip bests both. Hint.
You CLUELESS Fhuqktards be sure to keep Googling a first fhuqking clue. Hint.
