I started reloading for a 9mm Luger pistol a few years ago after purchasing a LEE 125 grain mold for this caliber. Not knowing any better at the time, as I had been shooting Winchester factory loads all of these years, I bought 1000 range brass from a supplier, and discovered that they didn't load the same as the Winchesters. After inspecting a bunch of them, and looking at fired cases, it was evident that the dozens of makes of 9mm Luger brass are all of different volumes and would require different load workups for most of them. Does anybody have a chart of equivalent volumes of all of these cases so some of them could be loaded the same?
