I recently found two 25 sheet boxes of J&C Classic 400 8x10 film in my freezer (out of date by two years but unopened and bought fresh from J&C). Can anyone suggest a starting film speed and development time for this film. I haven't done any developing in the last 2 years (college) and I don't want to use up any more of it in testing than I have to since it is not available anymore. I used to develop it in Pyrocat-HD but have lost all my development time records. I also have HC-110 and D76 available.
