I have loaded plated 115 gr. bullets for 9mm and my advice is to be very careful with how much crimp you apply. These are very short bullets without much bearing surface and with any amount of excessive crimp they will be squeezed down to the point that they will not touch the bore. At this point they will be good for making noise and not much else. Apply just enough crimp to remove the flair of the case mouth.
