Ted, I did not recommend oil to others, I only stated that I use it and mentioned my reasons. At the beginning of my post, I mentioned the reasons for using White Lubriplate or STOS, and implied that I would recommend these. I agree with you that for a gun used for clay targets in quantity, a grease rather than an oil may be preferred. However, I don't think a shotgun hinge pin is under the type of stress and friction that would require a zerk.
