I would have to look at my notes but have tried it in at least a dozen, though not always in one of my extreme temperature tests. But I do note temperature as part of any range session, and have noticed velocity variations at temps from 35-40 to 80-90 in some cartridge/bullet combos.
Am planning extensive shooting at both summer and winter temps over the rest of 2016 with a bunch of newer powders advertised as temp-resistant for a magazine article. Will know more as those tests take place.
