Loran C absolute accuracy is between 0.1 and 0.25 miles ( http://msi.nga.mil/MSISiteContent/StaticFiles/NAV_PUBS/APN/Chapt-12.pdf) but the repeatability is way better (from 60 to 300 feet, same ref).
When it was safe and fun to fly to Baja, Mexico I would record both ends of the runway with my Northstar Loran C. The absolute accuracy was miles off (geometry was horrible, way out of the coverage area), but once marked, I could return to the same spot every time. I kept a complete table of the Baja and west coast of the mainland permanently in my flight bag.
