Today I shot two rolls of TXP 220 that had expired Dec 1982. One roll was shot in my Pentax 6x7 and the other in an A24 back on my Hasselblad 500C. The film came out perfectly... for the task it was given.
I'm getting ready to shoot some Fuji Velvia 100 220 and I wanted to check out my cameras before wasting $20 on film plus $15 on processing and $28 on scanning - total of $63 per 220 roll. I have never ran 220 through the Pentax 6x7 and I haven't used the A24 back in at least 11 years. So I took the oldest 220 film that I had and ran it through to check for frame spacing and light leaks.
Sure enough the A24 back needs a needs a new light seal (I have 5 kits on hand). Frame spacing is fine. The Pentax 6x7 film is perfect - spacing is correct and the exposures are even (as expected as it was rebuilt by Eric Hendrickson
).
I have one more A24 back and two Horseman 220 (6x7 & 6x9) backs to check. I have 3 rolls left in the Dec 1982 TXP 220 Propack and I know what they will be used for

Very expired film can be very helpful!
