The Falcon T50B I have been testing was originally set up during the winter in the -1 degree temps, when the temps increased I saw no change untill about 12 degC ambient when it started to over range (50 actual reading 52 etc), and re marked the wheel to suit, since then I have seen no shift but its only been out on one hot shoot since so I'm checking it every time the temp goes above 20 degC down our range!
I cant see how a manufacturer can prevent material expansion so I would be very suprised if there was a scope that wasn't affected at all?
