You know, that thing "won't fit"... sometimes it is the shoulder, from one chamber to the next the actual shoulder length can differ. I had that issue in going from one rifle brand to another, bolt would not close on the round. solved it by re-sizing the brass down a couple more thou's.
Course you'd have to break down those loads all the way but you might check that.
