I did my first cast a couple of weeks ago and after a couple of hours they came out looking great. My question is though at first i had the lead around 650-700 and the molds were not all that hot. After a while I turned the lead up to 750ish and dipped the corner of the lee mold into the lead for a bit and nice castings came out. Is the 750 range too hot? I was using lead ingots from a vendor here and all of the lead in the pot was liquid at around the 650 temp. thanks
