Is this powder ok to use for 9mm pistols if not what is Asked by Keith 1 year ago Add your answer Product Owner - geraldsdNo this is a slow burning rifle powder. You want a powder that burns at the proper rate. Buy a reloading manual and consult it. For a beginner buy Lyman's. Look at the process and for a powder there that works for 9mm and that is available in this current market. Good luck and have fun. 41
