As far as I know,,,,,,,, all the lead mines in this country, were closed down by the EPA 10-15 yrs ago. I don't know if lead can be imported or not, under the present EPA rules.
The lead in retail circulation at present is all recycled, and wont last forever. The current national/Government fad about converting cars, and other modes of transpotation to electric power, wont help the prices, or the supply either.
Until or when the government bans/ eliminates black powder sales, and individual posession of it, someone will make it to sell retail. So I buy it while I can.
