Dacur, It is a myth propagated by H.. to sell powders. The military didn't buy it. I use my loads over 40 degree swings (70 - 110 degrees F) all the time: no diff in shotshell and rifle.
Also, even H... Extreme Price powders have some temp sensitivity, all powders do. The impact of these variations are over rated.

70-110 isnt really a good test. I have never heard anyone complain about issues shooting between 70F and 110F, as you demonstrate, in fact i believe I said something exactly to that effect
"A load developed at 90 degrees which is then used at 40 degrees is going to show a lot more variance than one developed at 80 then shot at 120......." .... As I said the problems come when a load is developed in warm temps, then shot in cold temps.... I never said hogdons extream powed has NO temp sensativity, but its a proven fact they have LESS
Before you respond, are you honestly trying to say its a myth that cold weather produces lower velocities?
