Just for the record, from the world's foremost authority on improper film loading, you will get exposure on reversed film, it will be much fainter and of very low contrast. I know you have since discovered the problem but I am compelled to share my hard won knowledge on this subject, particularly since it's about the only thing I am absolutely sure of as far as large format is concerned.
Thanks for the reminder about keeping developer fresh, perhaps that's one lesson I won't have to learn the hard way
