Well, I've tried my hand at casting finally. The issue I'm having is wrinkles in my bullets. I have a lee #4 pot and a lee 200gr mould. I have the pot set at 8, and I have warmed my mould as stated in many posts here. I cast several sacrificial boolits to ensure the mould is up to temp, but the wrinkles never go away. They get less, but never go away.. Any suggestions? Please help.
