I have used Lee case size lube on paper patch bullets for years. You can feel the smooth wax coating with a tight patch. The patch glides through the bore. Cleaning the bore is easy.
I have experienced no down side to a wax coating in the bore.
I wrote to Lee about this and they said they would look at it.
Ed Harris has been lubing cast bullets with thined Lee case lube for years.
It is a die makers wax and very useful
