Just wondering what the most temp sensitive powders are that you have used. I hear the term “temp sensitive” used quite often, but I’ve never really had a bad experience personally. I mainly just load hunting Ammo and test it during the spring/early summer months when it’s comfortable to shoot. I can see where working up a max load in cold January would show some pressure in hot August, but I’ve never experienced it myself. With powder hard to come by I was just wondering about it. I know there has to be plenty of people working up loads with powders other than what they normally use.

Doesn’t mean it’ll be too hot to fire. Can effect POI and accuracy especially at longer distances where minor velocity spreads matter more. -

A quick check of a calculator.... using my 6.5CM numbers
2 powders of exactly the same charge with a difference in temp sensitivity of 0.1 moved from 70f to 90f would differ from each other by about 4" of drop at 1000 yards.
