I loaded some 9mm with cast 158 gr. SWC

They were seated a little long but shot and fed great, fit the mags. They ran 1000 fps using Longshot powder. I may have used some AA#7 too. You could probably work up a “hot” 147 gr. cast to maybe 1100 fps, but that would be about it. Cast is more slick and you can go faster at the same pressure. But you won’t generally find that on the shelves. At its very best the 9mm about equals the .38 spec. +P. But it’s best left to 124 gr. loads for the highest balance of speed and weight.
