I have six rolls of 135 format Maco IR820C, which I believe is the same film. Mine expired in 2008, and is listed as an ISO100 film. I figure it's probably either fine at 100, or needs to be shot at 50ISO, plus compensation for the Zomei 720nm filter, which I have seen recommended at 4 to 5 stops when used with Aviphot 200 based films (and I have used at 5 stops, and it seemed to vary between OK and overexposed, but I was still metering at 200).
I'll be getting it out again this spring and summer, so this thread is very timely for me!
