OK; I set the Littleton up today and it works, but my shot is flattening out in the coolant. I have the level about 4 inches from the roll plate, and I'm using straight antifreeze from Walmart. Is there a preferred brand? It is clear yellow, and I can see the shot fall to the bottom. I have a 10 quart pail with 2 gallons in it. Everything seems like it should make shot, but I got pancakes. I sprayed the roll plate with Drop Out mold release and the shot is rolling right off instead of sticking like it did with no coating. How do I get round shot?
