literally dirt cheap If you want lead real cheap, then go the the local gas station and pick up an old battery. drain the acid, wash out the case, cut the case, take out the lead, melt it down, take out the bits you don't want and pour the molten lead into what ever shape you want.
As a kid we used to make fishing weights. Caution, lead is poison. Breathing the fumes can cause brain damage. Rather then mess with old lead spend the money and buy the lead shot. handle with gloves. Orma L. Robbins Southfield MI 19 Years flying KR-2 N110LR http://www.aviation-mechanics.com
