My first cast boolits were from the 6 banger Lee TC452-230-TC using the Lee 4-20 bottom pour furnace. After warming up the mold, the bullets came out perfectly and emptied the 20 pound pot in short order. 500+ bullets per hour tumble lubed and loaded the next day (yes I know you should wait to let them age, but I couldn't wait and they shot great anyway).

Everything I learned was from online forums, fryxell's .pdf and yes, Richard Lee's sales flyer entitled "Modern Reloading".
