Hello, I worked up a load for my rifle this last summer that I am very happy with. Now I am a little concerned, I just read an article that said that IMR 4350 is tempeture sensitive is this true. will my accuracy change as the tempeture gets colder. my loads I worked up were tested in 70 degree weather. Is that going to change when the the tempeture gets down around 20 degrees ?
Thanks, Steve
