Sgt Preston here. I use Win 231 for my 9mm rounds & they all seem to print the target right where I expect to see them appear. For the record, I use 4.2 grains of Win 231 to propel 124 grain Berry's copper plated flat nosed bullets. I set the overall length to 1.090 + or -.005 & I taper crimp the brass to .378 / .379 diameter. These days I fire my 9's out of a Stainless Steel Springfield Armory 1911 x 5".The gun cycles perfectly everytime. Hope this helps. Sgt Preston USMC LLA
