Hello, Regarding 9mm cases: to trim or not to trim? It seems the general consensus online is dont bother trimming. The Lyman book states a 9mm luger trim to length is .751 but ive yet to find a case that even comes close to being that long. It only makes sense that all the cases are the same length so that your taper crimp affects each one identically yet a majority of posts ive read say dont bother trimming. So Im wondering, do you trim 9mm cases? why or why not? If you do trim the cases, what length do you trim to, do you find your shortest cases and trim everything to that size? If you dont, why not? arent you worried that the taper will affect each length differently?
