I'm not sure what it is, but if it will get hot enough to melt solder which is often 50% lead, it's pretty likely it will get hot enough to melt the lead alloy for casting bullets. It might take a while though, depending on how big it is. My Lee production pot holds about 10 pounds and it's 500Watts at 120Volts. It's about as slow as I'd care to deal with.
