bulk tungsten

 looking for best place get 50 or so tungsten bullet weights... and ds weights too

Literally: www.bulktungsten.com  That's where I go for bullet weights.  I have been using their "Champion" bullet weights for a year now and I have been pleased.  The cost is relatively low for tungsten, they're insert-free, and the black finish has held up.  They sell the weights as black or unpainted only so you'll have to look elsewhere if you want colors.  Shipping is pretty quick and free over $75. 

I don't know about bulk DS weights though.  Hope this helps.
