I did the reaming on my pre-model K22 Combat Masterpiece this summer, with the guidance and advice of some old hands here on this thread. Worked like a charm, and today my empties push right out with the extractor and are only the slightest bit "sticky" now.
Your experience might be similar to mine when you do this on your revolver: the reamer must have taken out microscopic chips, because there were no metal flakes at all from the cutting. Maybe I was just lucky that my chambers were close enough to size that the reamer just rounded things up and those few thousandths of undersize disappeared easily.
Now I have the reamer, handle, and cutting oil to do the job next time, if I run into this problem again.
