Excellent information on this site for any handloader - even if you only load Jacketed Bullets.

I always keep my media slightly damp.  Just use a cheap 99 cent spray bottle filled with water.  A few pulls of the trigger when you start a new batch, and you're good to go.

I would add a couple footnotes to his ALWAYS WASH YOUR HANDS BEFORE EATING warning as well--

1.  Keep your hand away from your face as well.  No rubbing your eyes, itching your nose, or fingers in the mouth for any reason until you've washed.
2.  Wash with COLD soapy water, using a gentle washing motion, not a hard scrub.  Cold water closes your skin's pores, and a gentle motion washes residue off, where scrubbing hard can rub residues in, and warm water opens the pores in your skin.

Rubber gloves are cheap and easy to use - take off the residue with the glove and toss it in the trash can.

I do this when sorting brass and sometimes when reloading.

Neoprene gloves.
Less sweaty that latex.

That was a really cool article. I personally do not reload, but I have always been curious about the proper procedures of casting bullets. I have only seen my Dad cast once or twice that I can remember, but I have always felt a little uneasy when watching the small lead bars be dropped into the melting pot (?) as he did it the garage (door open) with no more protection then a surgical mask. On the same token though, I have been shooting many times at the range and handled spent brass with no worries of lead contamination.
