Could someone elaborate how "lube" causes a dent? It sounds bogus to me, but I am open to plausible explanation.

Oil does not compress, so if you have excess oil on a case shoulder when you size the case, it has nowhere to go, so the brass is what gives.
Not bogus at all. I've seen plenty.

To elaborate on the above post a majority of reloading dies manufactured as of late used to full length size fired brass have a series of small holes in the shoulder area that will allow the lube to get squeezed out and help to prevent oil dents. A lot of older dies did not have these holes and oil dents were common if the dies were not kept clean. I would think that you would not see oil dents on new brass but are common on reloads where dies are used to resize and this can happen. If the OP's round is new it is probably from being dropped or subject to some other form of mechanical trauma.
