I have a wonderful little Hiwall, built by the great John Oberlies.  It is chambered for the .219 Donaldson Wasp, probably the short version.  I purchased a box of .219 DW from a commercial reloader.  They were apparently the long version, because they won't fit.  I finally got one into the chamber and fired it, but it was a struggle.  I don't want to go through hoops to find out what I have or to load for it.  Is there a gunsmith who could rechamber it for the long DW, rebore it to 30-30, or rebarrel it to some caliber where I wouldn't have to change the extractor?  I want a store bought caliber if possible, hence the 30-30 idea.  A gunsmith in Maryland or southeastern Pennsylvania would be preferred.  I would rather hear directly from that gunsmith rather than contact information. Thanks.
