Whatever lets you sleep at night, but your numbers are way off. The fact of the matter is you can get better BC and SD with a 140 grain 7mm than you can with a 100 grain 6mm. You end up with almost identical velocities and trajectories with over 600 foot lbs energy difference. Truth hurts don't it?
guess you didnt read the first page. And the differnce in energy is about 200lbs not 600. At the cost of being slower and dropping faster.
