Here's a scenario that might help understand the question. Let's assume that we have 2 bullets. One made of lead, one made of copper. They are formed in the same mold, loaded in the same rifle and shot at the same speed. What is the difference? Surely there is something, beyond what a calculator using BC and velocity tells us.
Your question is flawed. This is an impossibility. If two bullets are made of solid copper and solid lead, while being the exact same shape and size, the lead bullet will weigh more. That obviously means it won't be starting as fast with the same charge of powder behind it.
And if you want to switch it around so that the two bullets weigh the same, then their shape will be different. The copper bullet would be elongated and more aerodynamic, unless of course you wanted to make it a flat based round nose and have the lead bullet be a boat tailed spitzer...
