temperature stable powders

[big mike 2121]

Hey guys,

what are the most temperature stable powders out there for both 308 and 7 rem mag? I know there will probably be a separate powder for each caliber. Just want to find a powder that I can use weather its 100 deg. or 20 deg outside.

To some extent, all powders very characteristics with temperature. Some more than others.

The temperature range you give is fairly extreme. Therefore, I would consider learning the temperature/performance characteristics of the powder each rifle likes best and develop drop charts for the highest and lowest anticipated temperatures. Or do as some, a summer and winter load for each rifle.

There ain't no free lunches.
