Be advised that the fumes from melting lead are not simply harmful, they are, over a period of time, lethal.
As there is no degree of lethality, I think I have said enough on that point.
Melting lead should be done in the great outdoors, if possible, making certain sure that you do not inhale the fumes, which have an accumulative effect, or in thoroughly ventilated indoor space with a whacking great extractor fan sucking it all out.
Read this - not everything from the Californian legislature is as wacky as is made out - as a long term lead melter of HUGE bullets, I have excerpted the relavant bits from this document, which was aimed initially at the home caster...

(16 Dec., 1996 -- Oakland) Hobbyists who make their own lead sinkers, toy soldiers, or bullets at home will be warned about a previously unrecognized risk to themselves and their children, following lawsuits by the Environmental Defense Fund (EDF) under California's innovative Proposition 65. EDF also identified a substitute metal for melting that avoids the risk.
"It's not just the man at the melting pot who's in danger," said David Roe, EDF senior attorney. "It's also his children or grandchildren who aren't even in the house while molten lead is being handled."
EDF studies found that melting lead in hobby equipment not only puts lead into the air immediately, but also deposits invisible lead dust around the house, where children and adults can be exposed long after. "The problem doesn't stop when you put your lead-casting kit away," said Roe. "Unless you know how to do specialized cleaning, you've created a hazard like lead paint that stays in the house indefinitely." Ordinary vacuuming and dusting just stirs up the lead dust and creates more exposure.
"The best answer is either not to cast at home, or to use a safe substitute for lead," said Roe.......Companies that make and sell the equipment for home lead-casting (molds, melters, etc.) have agreed both to warn their customers about the risk and -- for those who decide not to stop the practice -- tell them how best to reduce exposure. The warning emphasizes the risk to children and pregnant women. It advises strong ventilation during use, and explains how lead dust can successfully be cleaned off of surfaces and floors where it settles.
The required warning is the first under Proposition 65 to include a graphic depiction reinforcing the product makers' "how to" message to their customers.
All major makers and catalogue sellers of the casting equipment have legally committed themselves to give the new warnings. Companies signing settlements with EDF include Blount, Inc.; Gander Mountain, Inc.; Lee Precision, Inc.; C. Palmer Manufacturing Co.; Cabela's; Lyman Products Corp; Midsouth Shooters Supply Co.; Midway; Do-It Corp; and Hilts Molds. The San Francisco law firm of Chapman, Popik & White represented EDF in its lawsuits against the companies.

Read and take the necessary precautions and all will be well, but ignore the safeguards at your peril.
Whether it is being shot at you, or ingested by you, or even dropped on your foot in sizeable amounts, lead IS harmful.
