If you mess them up, they sell them everyday...
Not for this nchawkeye. It is a 12 gauge ramrod for a Pedersoli. According to my drill bit gauge the diameter is 23/64" (I do not have the metric equivalent in front of me). I have not been able to find a 12 gauge shotgun tip that would fit a rod in between 3/8 and 5/16. I could use a shotgun jag but that would look hideous. A 3/8" rod will not fit down the ramrod pipes and no one makes a shotgun tip for 5/16." I suppose I could start with a 3/8 and sand it down but it might be easier to try and recover the tips I have now.
