If you are trying to get a heavier metal than lead, its going to be a tough endevor. After bismuth on the periodic table all your hair is going to fall out with radioactivity, or the metal will have a half life of micro seconds and be unstable.
I think that you are looking at bad data!

I stand by my original post:
Make a normal bullet out of aluminum and the BC goes down, make it out of tungsten and it goes up.

Aluminum has a density of 0.098 pounds per cubic inch;
Tungsten 0.630

edge.

Aluminum has a density of 169 g/cm^3;
Tungsten 1,088.

Edge is correcty in the fact that the Tungsten bullet will have greater momentum and resist slowing better than a lighter bullet with the same form factor...
