I have "painted" sticky cases with a Sharpie, or similar felt pen, jammed them in as far as I felt comfortable and the extraced and read the rubs to tell where it was hitting. Often I'm surprised that it's not where I thought.

Have you slugged the bore and made certain that it is not too tight too?
