For years I shot expired Verichrome Pan 620 in my Pentax 6x7. The reasons? I knew it had been stored at normal temps, because it came from the warehouse which supplied local retail camera shops. Because no one wanted it (this was the 1980s) they only charged me a nickel a roll. I used it for copy work which could be rehot easily. And, despite being 620, it could be used with a 120 spool in the Pentax.
Back in ye oldene dayz, Freestyle sold much expired film which they guaranteed. I used it for personal work in 35 mm with no problems that I was ever able to detect.
