I am looking at getting some new pistol powder. I load .380, 9mm, 40s&w, 45 acp, 45 gap, mainly 9mm and both 45 I like mid range to factory load charges. I would like to use one powder for all these if possible. I was looking at Hodgdon Universal or maybe Longshot. Or do you think clays. I have used tightgroup before. I just want a bulky powder to help prevent a double charge. what to you guys think?
