Casting with a PID Controller

[Kurt]

Sam, Don.
My thoughts exactly. It's not just casting bullets but loading the round. As well as the lube used.
Casting the bullets is the least sensitive and easiest part putting these shells together. Turn your pot on or start the turkey cooker what ever you have on hand and start casting and when the wrinkles are gone turn the temp down if you see frosting starting. Frosting is an indication the pot is getting the alloy to hot.
When I cast and the bullets are filled out I turn the pot back till the light goes off and leave it there through the whole casting session. My Lee pot does not have a amber light like the Waage had so when the mould is throwing a good bullet I turn the heat back till I hear the click of the thermostat disconnecting. I never used a regulated pot. heck I used to use a plumbing LP fired furnace and a 30# cast iron pot and those bullets shot just fine. Didn't like the furnace because it was to loud and I had to do it outside in the heat of the summer and cold of the winter.
Work more on the casting procedures then how to regulate the alloy with in 5 degrees.
