As the rifle bbl in a drilling are generally built to a minimum contour I would for sure be leery of one of the intensity of a 7x57R having been "Relined". That alone would take this gun out of the "Like New" condition he listed. Even if he had honestly not noticed it, he should have refunded shipping Both Ways, after that was brought to his attention.
