You are absolutely right. But considering that 90+% of the bullets used in the world are basically lead (DU is real hard to come by for some reason!
), with some small amount of copper on jacketing them, they are basically considered lead.
Changing density but not changing shape is what kgwedi did by adding weigh inside his car but not effecting it's aerodynamics. And I applaud his diligence in his testing, no small effort that. And predictably, on a highway run, the weight mattered little. In town I am sure he would have seen a much greater effect, and the weight would show a big disadvantage in most situations. The only place I see weight coming in as an advantage is if you encounter intermittent resistance such as small hills, or snow and slush, that the weight helps you plow through without having to power through, but rather you use the kinetic energy you have already input into you car to get you where you need to be.
