I want to go to the range tomorrow and work up my 168 gr SMK's with the temp being around mid 20's. I will be using Varget as my powder. Do I have to worry about the temp affecting my test. Will I have to work up the load later again in spring when its warm? Thanks everyone in advance for your response. I really don't think it should be a prob but always like that extra confirmation from the folks that have been doing this for years.
