Bryan,
Thanks for taking the time to answer my simple minded queation. It's an honor to have a guy of your intelligence take the time. And I'm definitley buying your book. I was assuming the heavier the projectile, as long as the shape and density were identical, the less deceleration, and if you built a bullet the same shape AND weight as a "standard", it would have a B.C. of 1. And that you could easily build a bullet with a B.C. greater than 1 by making it heavier OR more aerodynamic. If, for instance, the standard G1 projectile was assigned a weight of 180 grains then most 180 gr. boat tails with long ogives would have a G1 B.C. of almost 2.
