Years ago I made 60 pounds of shot every morning M-F , it took a little over an hour. Two older partners were in charge of getting lead and making ingots out of a cast iron muffin pan (about 1 lb. ea) Littleton Shot maker was the unit. We started out using flame retardant hyd oil then switched to cheap liquid washing machine detergent. I also put a gear reduction on a concrete mixer to dry the shot the i added about 1/2 teaspoon of grafite to polish the shot.
All in all I made about 10 tons, was doing a lot of trap shooting at the time.
