Ok. So I have read Speer and Hornady's book on reloading and still have one question that I can't figure out. I am wanting to reload plinking rounds for the 9mm. (before i get jumped on for it, i inherited the equipment and some components for it and thought it would be a good round to start off with.) Back to my question. I am thinking about ordering some "plinking" bullets for it from Missouri Bullet Company. They are 115 gr RN, BHN of 18, with (here is the part thats throwing me) a diameter of .356. Typically 9mm is .355 if Im not mistaken. Will the .001 make a difference? Will this be load as usual or do I need to do something else?
