Yep! Watch some videos on it too, Duelist1954 has some I think. I did my .36 and some of my .50s and have been pretty happy with the results. Take your time and be sure to swab the bore and clean the tool every time you switch the sandpaper. I had best luck backing the sandpaper with double sided carpet tape and then cutting it out using the supplies piece of sandpaper as a pattern.
