I have a dilemma, i have never used Green dot or Hercules Unique powders for anything other than shotgun loads. i have recently bought dies and a mold for my SW40VE. my question is what type of powder would be best all around for number of loads and quality. Now the only problem is, my Hercules powder is the old stuff in the paper can with a metal top. 35-40 years old. being that the .40 hasn't been around that long, i cant find any load data for that older powder.
