New Army "Caliber Configuration Study"

[stanc]

Huh? Steel core bullets in the same form factor as lead core bullets will have a LOWER BC than the heavier lead core bullet.

That's true. But, I specified the bullets being the same weight.

If you have two bullets of the same weight, same ogive, same boattail, but one is longer due to lower density core material, will it not have a higher BC?
