I was bulk rolling film t-max 400 expired in 1996. I’ve been shooting this for awhile now. I had three rolls and this is the last. Sad it’s coming to and end. I seem to get about twenty 36 rolls from each tin. It’s a fun thing to do as you can have as many frames as you want. I tend to do 36-40 frames on a roll but you could do less if you are testing a camera or something. I developed five rolls of this stuff this week and now need to scan it. I developed them with Kodak D-76 for about 9 minutes 1:1 ratio. It was 76 degrees. The film seems to be pretty good even though it’s decades old now.
