Does anyone know or have some reliable info or site that pertains to todays powders, to see which ones are effected by temp and which ones are more consistant ? I have been on multiple sites where one states that a certain powder does not deviate but then another person says it sure does. I have never loaded for BC mountain conditions and would like to weed out some of my powders that might/will create a performance drop. Any help as always would be greatly appreciated and would help everyone at the same time.
