During my early days reloading I cast a lot of bullets, always looking for wheelweights and linotype. During my gunsmithing school days we would go out to the range on the days the Law Enforcement students practiced. We "mined" the berm for the recently shot lead bullets, took our booty home and set the LEE production pot up outside and cleaned up the lead and cast it into ingots. It was recycling in the truest sense, our bullet cost amounted to the cost of the lube. Almost like getting bullets for free.
