Specific gravity of tungsten is around 19, as opposed to 10 for lead.  Therefore if you replaced an equal volume of lead with tungsten it should weigh about 1.72x the amount you removed.  This is rarely achieved in true life, however, especially if you are using tungsten shavings in an epoxy slurry--even with a fairly dense slurry, the multiplier is usually more on the order of 1.5 or so...
 
I ordered mine several years ago from Hi-Temp Specialty Metals in Willingboro, NJ phone 609-877-8200 (Tungsten crushed, #8 mesh, 17lbs for around $100).
