Besides casting boolits, I also cast fishing sinkers and jigheads. Since I get my lead for free, I give these away. One unintended consequence is that it I have probably received more lead due to these freebies than I have given away. Just last night, a friend who I gave maybe a pound of sinkers showed up with three ingots that probably weight five pounds apiece. I gave another guy a dozen insulator pins with the heads intact and he gave me a 20 pound ingot to make up for my "loss". Another fisherman gave me a cannonball trolling weight and the contact for more lead insulator pins that half filled a pickup truck.
Scripture says, "Give, and it will be given to you. A good measure, pressed down, shaken together and running over, will be poured into your lap. For with the measure you use, it will be measured to you.”
