Where I work, there's an environmental department.
Got to talking with a fella from the enviro department and mentioned I was always scrounging soft lead for my cpa and ball revolvers and muzzleloading rifle.
He said he'd see what he could do.
Went out to my vehicle one day and found 40-pounds of soft --- dead soft --- sheet lead used in roofing in the back of my vehicle.
He later called me and pledged me to secrecy. He said that if the enviro office takes it in, it must be "properly disposed of."
This means paying a contractor $$ per pound to haul it away to see that the nasty, evil, toxic, malicious lead doesn't sneak into the house at night and slay the poor, innocent children as they sleep in their beds.
Or words to that effect.
Anyway, if you work in a big corporation you may want to get friendly with the folks in the enviro office. They're not ALL raving tree-huggers.
Incidentally, I melted all the sheet lead down and cast ingots. Gave the enviro guy a bright, shiny, un-wrinkled ingot. On the back of it I stamped 0.999 GOLD.
He said he was going to spray-paint it gold and use it for a practical joke.
I don't know if he ever got anyone with it but sounds like a fine idea!
I also fill a box that printer paper comes in with alternating layers of newspaper and plywood cut to fit inside. This stops any .22 or cap and ball projectile. I keep the box bound with duct tape and made a handle on top to carry it. Pin my targets to it, it doesn't blow around in the wind, and take it back home when done.
The last one I dissected, after it got so burst at the seams it could no longer be repaired, netted about 10 pounds in .36 and .44 balls and conicals, with a few .22s too. It all goes back into the melting pot.
Printer paper boxes, newsprint and scrap plywood or 2X4 lengths are easily found for nothing. The box won't stand up to a .38 Special or any round more powerful, but it will stop a .44 ball propelled by 40 grains of FFFG. Good enough for me!
