Sierra Bullets: shutdown of the Doe Run lead smelter shouldn’t affect ammo supply

The recent shutdown of the Doe Run primary lead smelter has some people wondering what effect this might have on lead supply for bulletmakers. Sierra Bullets issued the following statement, which I’ve quoted in part:

First, Sierra buys lead from several different vendors to maintain constant supply.? Second, this facility only smelts primary lead or lead ore.? This is lead ore that has just been brought out of the earth.? Sierra uses no primary lead at all and never has, so we use nothing directly from this facility.? The lead we buy from Doe Run comes from their recycling facility in Boss, MO that is about 90 miles away from the smelter that is closing.
The facility we buy from is still going strong and delivering to us as scheduled.? The lead from this facility is from recycled lead, mostly coming from car batteries.
Our supply should not be in jeopardy and we do not anticipate any changes in our supply chain at this time.? Could the lack of primary lead create a little more demand for recycled lead?? Sure, but how much is unknown.? Could this increase in demand also create an increase in price?? Sure, but again, by how much is unknown at this time.
