I went the rounds last month.
The big recycling places would not sell me scrap lead. None of them, for any price! They say they are under contract for materials and do not resell to private individuals.
Every "chain" tire shop (Sears, Tire Kingdom, Firestone, WalMart, etc) has a contract with Exide that Exide takes their WWs with the scrap batteries.
As a matter of fact I used to buy scrap alloy wheels for $5 each from all of those places (I used to be a mechanic and tire tech in some of them) but now the respective Corporate offices are demanding all scrap wheels are returned to the warehouse and the company sells them. Used to be when I worked there, if our (mechanics) cars needed tires, we were allowed to dig in the pile of old tires in the casing room. Now, they are under contract with a tire company to haul them sort them and resell any decent used ones to a used tire seller- so no more freebie casings. That used to be a great deal!
My only source of lead is a friend who is the general manager of a large (5000 cars per year) auto junkyard. They pull WW and valves from scrap alloy wheels to sell to the smelter- plus I get battery terminals and odd lead scrap from them, but I have to get there before about 3 other core buyers do to buy it- when the buckets are full it's first come first served.
The state public range has to my knowledge nver mined the berm or trap fields and I know when I shoot there the berm is literally just a pile of bullets with some dirt on them, but they don't allow berm mining.
