I have never bothered reloading 9mm because I could buy practice rounds cheaper than I could load them. I now need to load some. 9mm max case length is .754" I am finding length variations on mixed once fired brass from .740" to .752". Unfired Remington brass was .747". Fired Remington is running .747" to .749". 19mm=.748" What is your minimum case length? Fiochi and GFL are running short while Winchester is all over the place. I have been segregating the brass to over and under .745"
