I'm using a Lee Pro 420 (220v, heats up really quick, glad I went that way) and Lee molds at this time, and a Lyman thermometer. @800 on the therm, just wasn't getting good pours, lots of wrinkles, bad fillout, even with preheating molds and being very careful.
No signs of frosting, so I just started cranking the temp up. Therm is reading over 1000 deg and the lead starts really flowing well. It is now a fine stream instead of like pouring syrup. Mold fillout gets really good, real square consistent driving bands and still no frosting.
Obviously my thermometer is off by a couple hundred degrees at least. And I bought the Lyman because it was more expensive than Lee so it should be better, right?
But it was like a whole new level when those molds started filling out like that. Like a light came on.
Who makes a good, accurate thermometer?
