Looks good. How many BTUs is your burner? I'm thinking about picking up a 58,000 BTU propane cast iron fryer from Bass Pro. I think they're on sale right now.
don't remember the BTU's. it the king kooker brand. i just barely had the gas flowing and it melted lead just fine. in fact, i had it so low that it blew out once
dlbleak, I'm still trying to educate myself about bullet casting. I thought this bit of info from Glenn Fryxell's book on lasc.net was interesting. The range scrap you cleaned up might be within the useful hardness depending on what you are casting.
I typically wash my range scrap, so I have to be real careful of the water issue. I usually leave a layer in the pot to start with the next time. I'll let that melt down, then add range scrap slowly via spoon. I'll touch the bottom of the spoon to the melted lead, let all the water evaporate off the scrap lead, then slowly lower the spoon into the molten lead.
Put it all in the pot cold and let the pot evaporate any water from washing as it gets up to melting temp. I have scars on my arms from a sudden rainstorm when I was casting outdoors.. Not fun. Blitzfike
