Bullets in plastic container with powder & Air Soft BB's.. Swirl around for about 3 min.
Bullets on tray ( non stick aluminum Foil ) some standing some laying . Really doesn't make a difference.
In oven at 400dg for 25 min.
When done take right out of oven & dump onto a cooling tray lined with non stick foil. Swirl around lightly for a few seconds so bullets don't stick together. You will feel when they don;t stick.
That's it. Let them cool & cure over night. Size & load. Easy.
