Narrative:

While navigating between 2 vors (on a victor airway) with LORAN as a backup, my attention was diverted explaining a related subject. I soon realized we had diverted slightly west of course with R2503 nearby. Although ATC didn't mention anything, I'm not sure how close we flew to it, not knowing the exact accuracy of the vors. I thought it was best I file this just in case we accidentally penetrated the restr area.
