[QUOTE="lancetkenyon, post: 1530925, member: 68875"] They do not necessarily correlate. Take a look at various higher BC bullets in the .600 range, and you will see. 90gr .223 SMK, 140gr 6.5 HVLD, 190gr .308 NABLR, etc. All .600 BC, but greatly varying SD. Bullet diameter and weight have to do with SD, not BC. Better yet... 7mm 150gr NABLR SD .266 BC .546 Part SD .266 BC .456 7mm 175gr NABLR SD .310 BC .648 Part SD .310 BC .519 [/QUOTE]
