I get mine for my labor picking it up off the face of the berm at my gun club. After a good rain the berm is covered with exposed bullets. If there is a shooting area near where you live, check out the backstop. If I spend 10 or 15 minutes picking up range scrap after a shooting session I easily have about 10 times the lead I deposited.
I don't use this guys technique, I just pick them up, but you get the idea.
