I have a different kind of question about powder. I have three dillon presses one for loading 40 one for loading 9mm and one for loading 45. I have finally used up-all my 45s so I need to load a bunch more. However I have not used the 45 press in probably 3 years and there has been powder sitting in the powder measure for all that tome. The lid has been on it and it has been covered but do you think the powder has gone bad. Should i just be safe and throw the powder out and start fresh.
