Do you have a scientifically graduated cylinder?

Drop them in water and measure the displacement. You know the mass of the bullet, and the volume of displacement in water will give you a cubic centimeter measurement.

Density = Mass/Volume

If you don't have one fine enough, just use more bullets to get a bigger difference and then divide your final number by that number.

Machine guns are awesome until you have to carry one.
