Was PCing some today and didn't seem to get very good coverage with the shake and bake method. After 2 batches and one of them being coated twice it hit me, I didn't pre heat the boolits before putting them in the tub to shake and swirl. 3rd batch heated to where it was difficult to hold. Wow what a difference it made. No myth there. It made a big difference in how well it coated. At least it made a big difference for me.
