I need some practical advice on how to adjust for temperature changes between when loads are developed (summer and early fall) and when in the field hunting (mid-late fall). Up to now I've only used Hodgdon Extreme powders and have not worried about temp changes from a load perspective. I'd like to start working with other powders (specifically Reloader 19) and I'm wondering what you all do when working up loads and developing drops during the warmer months when you plan to use them in the colder season. Are there any rules of thumb that I can use to adjust or not worry about the change? Thanks.
