Lead is much denser (more weight for the same volume).  Zinc is just about the same denseness as cast iron (will float on lead).

per pound... they both weight the same... a pound of lead is the same weight as a pound of zinc (which, oddly enough, weighs the same as a pint of beer... approximately... but I degress)... "." A pint's a pound, the world around" ... approximatley ... but enough about beer...

Anyway, lead has a specific gravity of 11.3, while zinc has a specific gravity of 7.3, so Lead weighs 11.3 divided by 7.3 (about 1.6 times) more than zinc for a given sized object.

Unless you are particular about your lead source, it will contain tin and antimony and bismoth and probably a few other things in lesser amounts, so "range lead" will weigh a bit less than pure lead.

You can determine the weight of a given diameter projectile made of a number of different materials at http://lassengunsmithing.com/html/ShotWeight.htm.

I figured it was a joke... otherwise I would have mentioned that a pound of feathers was lighter than either  ::)
