I've found on my Mihec moulds that if I lube the pins using Kroil they slide easily, don't build up gunk, and the Kroil has no effect on bullet casting in that it will not cause wrinkles if it migrates into the mold cavity. I'll bet I have the same .45 mold as you, and it is a good one.
(I've actually started storing all my iron molds wiped down with Kroil inside and out...)
