So, where are we getting the lead now for bullets?
Given your screen name, the snappy answer would be we’re digging it out of back stops and melting it to pour in casting molds over a campfire...:-)
Actually, a good question that I’ve not seen answer to but a SWAG would say foreign sources.
Virtually all the lead for bullets comes from recycled lead. This comes from car batteries, wheel weights, and other sources.
There is a large lead recycling smelter reasonably close to the virgin lead smelter that was shut down, I have read.
