I have switched to using AA#5 in my 125gn 357 self defense loads, which typically stay stored in my car during the summer. I know AA#5 is close to Bluedot on the burn rate chart and Bluedot has the temperature senstitity problem when it comes to heat. Is that a common problem with powders in that burn rate zone, or is it just specific to the blue dot powder formulation?
