Blue Dot load?

Just a couple of observations about Blue Dot. It is a temperature sensitive powder in that loads developed in cold weather will operate at higher pressures in the heat of summer. This based on case/primer observations and just the feel of the load. Not very scientific I know but I have 30 years of reloading experience to go along with it....

I've stayed out of this discussion so far since I've never loaded anything with Blue Dot. The reason is that a ladies champion shooter's husband owned a gunshop in OKC back in the 1970's when I lived in the area. He stated that he loaded her .357 ammo with Blue Dot in the winter, but switched off as the weather warmed due to pressure problems. I figured I didn't want to take a chance. And it did get really hot in Oklahoma.
