You definitely should have noticed a difference in POI with a 14 degree Celsius temp change, about 7 or 8 inches according to my calculations. If you noticed none, then something else was at play here.
Aerodynamic jump is the spin related vertical component of a crosswind and we've seen it on many occasions and always allow for it beyond 1000 yards or in strong winds. Bryan covers it well in the chapter on wind deflection in his second book, but his AB program doesn't allow for it unfortunately, so you have to do a simple fudge factor.
The simple allowance we worked out from Bryan's info is .3 MOA for every 10mph of full cross wind, taking it off for a 3 oclock and putting it on for a 9 oclock. It seems to be approx the same for all calibers and bullets. Maybe Bryan can come on and verify if we've got this about right? It certainly seems to work for us.
